Cisco wlc force ap failover. I have two WLC 2504 with 7.
Cisco wlc force ap failover 140 and 2802i Access points This is a new setup and after configuring the WLC and adding the APs, a handful APs did not join due to So let me see if I understand this correctly: You have three sites with WLC. When the primary RADIUS server goes down, the WLC will failover to the next active-backup -1) Navigate to the "Devices" tab in Cisco DNA Center. There are a total of 30 APs. AP group names in 5508 must match policy, RF tags in 9800CL (RF profiles at both also must match) by doing the above you Consolidated Platform Configuration Guide, Cisco IOS XE Release 3. We are testing the WLC 8. So I would check that and also make sure that I have the picture before I repeated the same tests with the High Availability in the AP configured with both WLC (HA SKU and PRIMARY WLC). Once an ap first joins a WLC it keeps the ip of the controller and the info set in Hi. If H-REAP is working during the reboot stage, you should not loose your association and/or authentication. AP fallback of course should be Hi, I'm newbie to 9800 WLC, I have setup VM on SSO mode and all working, AP can synch, user can connect,manual switch failover is working. Layer 2 vlan / Layer 3 vlan and DHCP Scope are configured on 4507. Once it's offline, the APs should move. Both sites are using their own WLC 2504. 100. No secondary or Depends on the AP modes. 188. Mark as New; Make sure master WLC is disabled and mobility is up between all WLC's. In other words, fallback is disabled. The redundancy mode on this is a HA Hi guys! I have next question. 161. You can see the controller name in GUI mode on the Monitor screen of the WLC. I want to join them to the same group and make a failover solution. WLAN1 -> WPA2 (TKIP) + PSK. Check the mobility group, make sure the WLC host name on the high Scripting has been mentioned, but even if I run a script I don't know how to copy to the EWC-AP controller partition. 0 Config ap secondary-base “invented-WLC2” ap-name 2. - Controller WebUI is no longer - Some suggestions : 1) is the ap in local mode 2) Is NTP configured and working on the controller 3) Check the controller-logs too when this happens 4) e nsure there is a Stephen, I will be deploying 3 4400 WLAN controllers, 50 licenses each. • In the Primed Join Timeout field, enter a value between 120 and 43200 AP failover priority determines To perform a forced failover using CLI, use the following command: config ap next-preferred-master cisco-ap-name forced-failover. 6. IP to maintain AP CAPWAP during failover once HA/SSO is formed Two units are using a dedicated Redundancy Port (now called HA-Interface) to sync Role election happens at You need to maybe just shut the power off to the primary to force the secondary HA to take the primary role. Chapter Title. Once the AP has received a Discovery Response from any WLC using any of the WLC discovery methods, it selects one controller to join with Hi board, one question regarding the configuration of deterministic AP join on a WLC. 61. This document also explains how to set up Primary AP Failover and Electing a new Primary. If the AP is in local mode once the controller goes down all APs are down and clients are disconnected. So, you may set the primary/secondary/tertiary WLC per AP: # IOS-XE config stlye ap Basic understanding of WLC failover and mobility groups. radius-server dead-criteria is used to define the number of time a – If the new WLC has a higher AP count than the previous, the 90-day counter is reset. What would be the normal behavior of having this To force a switchover between boxes, either manually reboot the active 9800 WLC or run this command: # redundancy force-switchover Break HA Clear HA Configuration in both 9800 You can monitor the master Cisco WLC using the Cisco Prime Infrastructure Web User Interface and watch as access points associate with the master Cisco WLC. I configured APs with static IP, The Active WLC (could be the primary) on HA AP SSO the APs under the show AP summary will show as Active. 2. When I go to Management>Licenses, it shows that I have a 500 AP Issue the redundancy force-switchover command on the Active WLC. On WLC the interface got IP Then When you have that completed and the 5508's configured, you would add the wlc's to the same mobility group and make sure that the mobility groups is up. in normal mode, the primary WLC is active and the secondary WLC is standby and the "show redundancy sum" The new High Availability (HA) feature (that is, AP SSO) set within the Cisco Unified Wireless Network software release version 7. We have setup the same mobility groups on both WLC. If you configure global or AP-level HA (not to be confused with SSO), then yes. Therefore, the access i have two controlers in HA N+1 i want to failover all the access points from primry to secondy what is the best method to avoid downtime (i am havinj around 400 access points on the 5500 HA SSO, we need to update the active wlc, perform a redundancy force-switchover, then update the sec wlc certificate. Here is my Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide, Cisco IOS XE Amsterdam 17. Since the AP have connected to US WLC, I need to change the primary controller IP on Please click Helpful if this post helped you and Select as Solution (drop down menu at top right of this reply) if this answered your query. Then I would Cisco recommends that you have knowledge of these topics: Catalyst 9800 Wireless LAN Controller (WLC) High Availability Stateful Switchover (HA SSO) Components Reboot BOTH together. 0. However, when simulating failover, turning off the Primary WLC, I saw that the Solved: Hi All, i have a EXISTING WLC 5508 with APs that are in static 192. Both the controllers are running code Step 1: Choose Wireless > Access Points > All APs to open the All APs page. However, this process is long and arduous when your AP's I am not sure tbh, as I consider this to be mandatory for my deployments just because of what it does. We can not tell exact time but normally It We have 2 WLC 5508 in HA mode with code level 8. A direct physical The test AP finds the production WLC using DNS. For APs in the second pair, trigger the AP pre-download. 3SE (Cisco WLC 5700 Series) Configuring Backup Controllers and Failover Priority for Access Points Finding Feature Master AP Failover and Electing a new Master Cisco Mobility Express is supported on Cisco 1560, 1815I, 1815M, 1815W, 1830, 1850, 2800 and 3800 series Access Points. In case that one WLC is down, the remaining WLC cannot cater for all 30 APs. I would not create one and use the default management interface. the mobility group is also configured however in the mobility summary the control path shows down and mping Prerequisites for High Availability External Interfaces and IPs. I understand how this operates when the controllers reside on the same network Hi all I have 2x 5508 in SSO mode I performed a failover test (by executing command "redundancy force-switchover" and after the standby controller rebooted, HA seems config advanced timers ap-fast-heartbeat all enable 1what is the effect? The ap-heartBeat-timeout has to be 3 times the value of the ap-fast-heartbeat timer, but why? Does WLC High Availability (AP SSO) Guidelines This document is to provide education on issues we have seen with this feature for the various WLC code versions. Once you has configured the AP pointing to incorrect or We use WCS to migrate AP's to "backup" controllers prior to making changes to our primary wireless controllers. THE WLC have the same software version installed. 3 and 7. Yes the WLC's should have Cisco Wireless LAN Controller Command Reference, Release 7. Fallback of the AP's works, when I I update the AP from TFTP and try to join again and saw that AP joined to WLC , then download software, then updated , and after update doens't join to WLC . If the AP's don't move, then there is something else wrong. 5 apparently has a BUG so the Evaluation License in the HA SKU WLC keeps counting down even though the AP is no more connected to that Backup Cisco Wireless LAN Controller Software. We will have about 75 total lightweight APs being managed. However, when simulating failover, turning off the Primary WLC, I saw that the Secondary WLC did not No it doesn't sync configuration. 0 During an HA SSO failover event, all of the AP Nah. Overall 1. 5 Cisco IOS. The controllers talk to each other using the Redundancy Port (RP). 251) = Backup When the Primary goes offline, my AP moves to the BACKUP wlc as In off mode, the WLC supports failover only. The overall goal for the addition of AP and client SSO support to the Catalyst 9800 Wireless controller is to reduce major downtime in wireless networks due to run"show ap summary" to get the list of access point associated to the first WLC and then use the commands config ap primary-base <controller_name> <ap> Hello Cisco-WLAN-Community, I would like to report a WLAN-AP-Join-Problem that arised here during SW-Upgrade on 9800-80-WLC to version 17. (4402-a) >config network ap-priority enable (4402-a) >config ap priority 3 3502-d. This will prevent AP's from joining controllers randomly. I'd like install new vWCL version 8 and move all Hi Experts, I have a brand new Catalyst AP CW9166I-ROW with catalyst Image. The "force" means that the controllers will both Hello Guys I have to move few APs from site A to site B. I have an RF-Group, AP Fallback is enabled and Failover works perfect. 2. 1 is the primary controller and 1. – If the new WLC has a lower AP count than the previous, the 90-day counter is not No. x 0 AID mismatch with dot11 rec during force purge : 0 AP In a Cisco Catalyst Controller 9800 SSO deployment, will failover occur if the interface or port-channel of the active WLC is physically shut down? Wireless LAN You are correct, but you need to configure the WLC's in the mobility group in order for AP Failover. Make sure that AP's are primed properly to have the primary and secondary wlc's configured. I am not sure how to join the APs to site B WLC. ♦ ♦ The Cisco_AP field represents the name of the Cisco AP. I have two WLC 2504 with 7. It is added to the AP default group. I plan to add a NEW WLC 5508 as a Primary controller with I have a 5508 controller where the GUI says that there are 400 AP licenses loaded on the Monitor page. The perfect state of a Cisco WLC cluster Hi, My client is having two Cisco WLC 5508. One is at location A & another at location B They want to configure failover between these two WLC’s i. Step 2: Click the name of the access point for which you want to configure link latency. you need to configure each wlc and make sure that both are in the same mobility group in order for the ap's to know of both wlc's. I need to replace virtual WLC. WLAN2 -> WAP2(TKIP) + 8540 Wireless LAN Controller supports Right to Use (RTU) licensing model similar to the Cisco Flex 7500 and Cisco 8500 series controllers. I configured Mobility group and split the APs between 2 WLCs by configuring Primary Controller on each AP. Failover happening from Primary to secondary active. Each site has two WLC, the primary/main and the secondary/backup. If they don't, simply enable the LAN ports If the AP does not migrate, you could try changing the "priority" of the AP, which would force a lower priority AP off the controller (and presumably onto the other controller) config ap priority 4 AP_name. What is the recommended limit one WLC can handle ? We can divide the load on the controllers but in To force a failover to the standby unit, use the following command: Router, (B) Bridge, (T) Telephone, (C) DOCSIS Cable Device (W) WLAN Access Point, (P) Repeater, (S) RF group name need to match in both WLC's. For this to work, the config ap priority {1|2|3|4} <Cisco_AP_name> Here is an example of this CLI usage. Both are up, but it looks like there was a failover to the secondary at some point. When you force the failover of the primary to A larger issue though is that when I use the command "redundancy force-switchover" on the primary I see the following behavior. 16. These have been converted to When failover occurs the WLC will kick off other Low APs to allow the Crittical APs to register? Lastly can I use AP Groups or WCS to push a template with AP Failover Priority? There´s no preempt for Cisco WLC HA process. Cisco Says: " There is no preempt functionality. IP to maintain AP CAPWAP during failover once HA/SSO is formed; Two units are using a dedicated Redundancy Port (now called HA-Interface) to sync I've 2 Physical WLC 9800 in SSO, and I'd like to know if it's possible to monitor the Management AP Interface to force a Failover if it's not reachable. You propose to set up a fourth AP is registered to primary WLC. the Hello all, Setup : 3504 WLC HA-pair, 8. This command will trigger a manual switchover where the Active WLC will reboot and the Standby WLC will take over the The ap's you do not want to failover, you should not configure the secondary WLC, but configure a false entry. 115. In our example, it is AP1. Once the first pair of WLC come 2nd Step, shutdown the LAN Switch ports on which the Primary WLC is connected so I force the AP going to HA SKU WLC. As I'm using the RP for Redundancy, the SP for OOB Currently we have N+1 redundancy connection between WLC in two different locations. If using N+1 make Hi AP cannot register on WLC 5508. For this to work properly, the . This is one method. Wireless Controller. I described exactly the same situation. Will clients stay connected to WLAN when the AP failover to secondary WLC. When the previous Active WLC comes back, it will not take the role of the Active The secondary HA-WLC will restart, download the configuration and the license storage from the Main-WLC and will restart again. Configuration Guides. The After a High-Availability Stateful Switchover (HA SSO) failover or reboot, a partial or complete configuration loss may be seen on Cisco C9800 Series Wireless Controllers AP failover occurred but the fall back option like primary WLC comes up it does not register with primary all the ap still in secondary. They buy a Cisco WLC 5508 with built-in license for 25 access points (AIR-CT5508-25-K9) and a WLC for high I don't know if that will work for you, but if it does then great. You would Please click Helpful if this post helped you and Select as Solution (drop down menu at top right of this reply) if this answered your query. " Then with "AP Fallback" enabled, I'd I configured SSO and works fine with the command: "redundancy force-switchover". Hello Friends, We recently installed 2 4402 WLCs. If the APs are in HREAP mode then they Even if i gracefully tested the failover by shutting the RP/Data ports to WLC, failover worked perfectly fine because i didnt touch the crosslink between the distro switches, and and zero SSID outage. Same result when I disconnected the PRIMARY WLC I do this all the time when upgrading. Cisco Mobility Express is supported on Cisco 1560, 1815I, 1815M, 1815W, 1830, 1850, 2800 and 3800 series Access The test AP finds the production WLC using DNS. Why should I care about High Availability? How long can my network be down? 1. Despite the fact, that this Access Point Link Redundancy • Power over Ethernet Redundancy AP failover takes ~45-60 seconds BRKEWN-2846 14 N+1 best practices BRKEWN-2846 15 WLANs Profiles and WLC1. If you want to force a switchover between boxes you can either manually reboot the active 9800 WLC or run this Config ap primary-base “invented-WLC” ap-name 0. Webex spaces will be moderated by the speaker until June 17, 2022. 0/24 with 7. After a Failover the APs on the secondary will show as "not Hi All, Over the last couple of days, we have this issue that has come up and causing grief - all APs disassociate and reassociate every minute or so. 0, a new feature called Backup Controller Support is introduced for access points to failover to controllers even outside the mobility group. 250) = Primary BACKUP (172. When the primary WLC fails the AP will move to a secondary WLC. DC-WiFi-SVC1-LAB(config)#inter DC-WiFi-SVC1 For me it is very important to make sure that all the AP’s and clients are synced to the standby WLC before a failover. If I do a 'redundancy force Best Practices for AireOS WLC's, Best Practices for 9800 WLC's and Cisco Wireless compatibility matrix When you force the failover of the master to an AP of your Hello, I'm using physical appliances, the RP for redundancy and a Chanel Group of 2 TenGig Interface for AP Management and SSIDs. But I still find wierd that if AP can't join the WLC, it doesn't try to failover. I can't seem to find anywhere this setting appears in any inventory report. You can will that 6 access point will switchover to failover wlc 2106 above then 20 sec. This process involves Both WLCs are using the same mgmt. 10 - High Availability [Cisco Wireless LAN Controller Software] - Cisco. But I notice when initiate The AP joined a WLC based on the failover priority order. Use the command "reset system force" because this instructs both the primary controller and the secondary controller to reboot at the same time. AP Hello I have noticed that if i configure the 5520 gui with 'High Availability' entries, i see them successfuly pushed to the AP itself. If you have two WLC and the 2nd WLC has no APs, then The HA deployment document provides information on the theory of operation and configuration for the Cisco Unified Wireless LAN Controller (WLC) as it pertains to supporting はじめに. WLC connects to 4507 as trunk port. 0, one of them defined as HA. Once the test AP has joined the production WLC, I want to direct it to the test WLC by using the AP's HA options by defining I understand you're explanation about SSO. Actually the AP fall back is enabled. Suppose that all is Does anyone know of a way or place that the AP Failover setting on the AP is reported in WCS. 1. The Cisco_AP field Solved: I have a very simple setup: WLC1 (172. After the AP reboots If you dont have any management system then: run"show ap summary" to get the list of access point associated to the first WLC and then use the commands config ap primary Hi, I need to configure AP fail over between controllers that reside on different ip subnets. . My Cisco recommends that you have knowledge of these topics: Catalyst 9800 Wireless LAN Controller (WLC) Stateful Switch Over (SSO) High Availability (HA) Redundancy I am not able to join a Cisco 1242AG access point to register to failover from a 5508 (50 lic) controller to a 5508 HA-SKU controller. 3) Click the "Edit" button at This document discusses how access point (AP) load balancing and AP fallback work in the Cisco Unified Wireless solution. American controllers completely go down, all the AP's that report back to them will(or should) failover to the European controller because of the HA setup From the AP Failover Priority drop-down list, choose one of the following options to specify the priority of the access point: Low—Assigns the access point to the level 1 priority, The WLC version 7. I can log onto the AP cli and "show running A flexconnect AP is connected to the primary controller. e. like I mentioned earlier, the easiest is setting the secondary controller on the 5 ap's that you don't want to join the wlc However when configuring the AP with the correct name, which results in it using the SITE-TAG it is supposed to have (filter application of tags as per regex). I use a dedicated VLAN to transport the redundancy sync and info, 'cause the two WLCs are in We use four WLC 4402 running version 6. The issue is DCs are connected via Layer 3 WAN so controllers are not on the same subnet. High Availability (SSO) Deployment Guide - Hello guys, I have a question and I would like someone to give me visibility on how the management gateway failover works. Force the AP to move to the secondary WLC and then boot the primary controller. TAC recommended codes for We have 2 WLC 4402 (wlc-a and wlc-b) setup on the same DMZ and 30 AP connecting to the first one (wlc-a). in case of location A We have a pair of WLC 5520s in an active/standby configuration. APs are configured with From the AP Failover Priority drop-down list, choose one of the following options to specify the priority of the access point: Low—Assigns the access point to the level 1 priority, So each AP would have its local controller configured as the "primary" controller and the data center controller would be "secondary. Dear All, Wish you all happy new year ! I have a situation to change the AP High availability : One of my WLC is decommissioned and replaced with other name and IP If any of the WLCs go down, the access point that is joined to the failed WLC recognizes this (keep alive (heartbeat) between access point and WLC). Reboot the first pair. TAC recommended codes for Cisco Wireless Controller Configuration Guide, Release 8. Step 3: Choose the Let us also say that in the all those WAPs are configured with an AP Join tags to say WLC 1. I physically shutted the If a controller has the maximum number of supported APs joined to it, the failover priority feature allows it to disconnect a lower priority AP, if a higher priority AP tries to join. We recently setup SSID for Wireless printers and VLAN 114 and 115 were setup on My query is to understand how much time will an AP take to failover to its secondary WLC(Backup) incase primary goes offline. Hello, I?m still involved in the deployment of 55 APs with 3 4402 WLCs in different cities, and I?m still having troubles with failover configuration. This way those ap's try to join a WLC that is not there while the I’m currently in a project where a school needs to integrate a wireless network. 5. The APs do not go into the Discovery state There are no real advantages between Redundancy mode vs 2 WLC, WLC-4402-25-1 & WLC-4402-25-2, are implementated. My questions pertain to load balancing Cisco Wireless LAN Controller (WLC) Configuration Best Practices -Quick Start Guide: Cisco Wireless LAN Controller (WLC) Configuration Best Practices of associated So as long as your active & standby 4400 in same mobility group all your AP already aware of both WLC. Cisco actually designed EWC to be able to handle >2 EWC seconds (inclusive) to configure the access point primary discovery request timer. You have to specify the primary controller in order for an AP to go How can I safely test this during normal hours? Reboot your WLC while associated. 168. 4 allows the access point (AP) to Wireless LAN Controller Election. Because all the interfaces are configured only on the Active box, but are synchronized with the Standby box, The document cover that information : Force Switchover. When your Hi, I exeprienced a reload problem in standby WLC, with HA in release 7. A single controller at a centralized location can act Both WLCs are using the same mgmt. You missed my point. 0 as a fail over pair. 2 is the secondary controller. (Shutting down the main Buenos días, estoy realizando una implementación de WLC 5508, los estoy colocando en un esquema de redundancia pero me surge una duda, cisco sugiere colocar los Login to the CLI of the active WLC and run this command to enable to console access to the standby 9800. Otherwise console access is locked to the standby WLC : Next, you force the AP in one pair to go to the second pair. I enable Fall back option also as per the So, I have two offices, one of them are 18 AP and one WLC and the second office is two WLC and 10 AP's. 9. I need to convert it to Meraki managed and i don't have a WLC. The WLC is on code 8. On WLC i have The 5508 does not have an ap-manager unless you specifiacally create one. This is an Honor-based licensing WLC Failover nouman_nabi. although it reboots Another way is to shutdown the LAN ports on the Switch to which the primary WLC is connected. I understand you're explanation about Hi, I have two WLC, each of them with 10 ap license, which means I can get up to 20 aps in total. Once the test AP has joined the production WLC, I want to direct it to the test WLC by using the AP's HA options by defining One possible solution that I found in Cisco documentation for handling AP configurations involves converting a CAPWAP AP to an EWC AP. To configure the name and IP address of the tertiary Cisco WLC into the CAPWAP access point from the I configured SSO and works fine with the command: "redundancy force-switchover". copy of the AP database is maintained on the Standby WLC. 7. No secondary or tertiary thanks for your replies guys. Cisco Wireless Controller Configuration Guide, Release 8. 2) Locate the access point you want to move, and click on its name to open its details page. There are APs about 40 pcs and ones cannected to vWCL vers. Beginner Options. 4. I will ship the AP to UK and let them to connect to UK WLC. i was told 5500 wlc need to be reboot for Hi I am hoping that you can assist We have installed a new 5508 WLC into a new buinging and also installed new 200 AP's which are 2802i. 3 HA AP SSO switch over with command redundancy force-switchover . Also, a WLC to be in the AP's Array list, it will either has to be statically primed (pri/sec/tertiary) or in the global back up WLC list. Is there any way to convert this As it is today, if the N. このガイドでは、アクセス ポイントおよびクライアントのステートフル スイッチオーバー（AP およびクライアント SSO）のサポートに関連する Cisco Unified Wireless LAN Controller（WLC）の操作と設定のセオリーにつ Hello Friends, We recently installed 2 4402 WLCs.
