Prime Infrastructure 1.3 + WLC 2504 - Enable LAG?

Hi everybody,
I'm facing a little issue using Prime Infrastructure 1.3 configuration templates to manage a couple of 2504 WLCs.
I'm using a Configuration -> General template to enable LAG on a couple of controller and when I try to apply it I get the error: "LAG mode cannot be enabled for 2500 series of controllers."
Obviously I can enable LAG locally on controllers, but then each time I try to apply the configuration template from Prime Infrastructure LAG gets disabled again.
Is this a known issues? Does anybody known how it can be worked around?
Thanks,
L

There is a defect in PI 1.4 that you can't enable LAG for the 2504. It's possible that 1.3 also affected

WLC 2504 with LAG

Hi all.
I`m configuring new 2504. I updated it to 7.4.100.60 and enabled LAG.
I want to configure interfaces "ap-mgmt" - for AP management.
(Cisco Controller) >config interface create ap-mgmt 69
(Cisco Controller) >config interface address dynamic-interface ap-mgmt 10.50.50.157 255.255.255.224 10.50.50.158
(Cisco Controller) >config interface ap-manager ap-mgmt enable
AP manager interface already exist on port.
So I disable ap-manager on default "management" interfase and enable it on dynamic "ap-mgmt"
(Cisco Controller) >config interface ap-manager management disable
Warning! You have no AP manager on this port.
The controller behavior will be unpredictable.
Are you sure you want to continue? (y/n) y
(Cisco Controller) >config interface ap-manager ap-mgmt enable
After that I have nice sh int summ, I can ping all interfaces, but AP can`t register on the controller "ap-mgmt" (10.50.50.157) interface
(Cisco Controller) >show interface summary

So my newly created "ap-mgmt" interface was thrown from LAG and default "management" interface was restored as AP Manager.
After reboot I can`t ping "ap-mgmt" (10.50.50.157), it`s clear why - because it have no physical port associated with it.
My question is why I can`t make other than default "management" interface as AP Manager when LAG enabled?
I try 7.4.100.60, try 7.4.100.0, try two more 2504 results the same.

>it's recommended to put both of them into the same VLAN and the same subnetIn documentation I don`t find such recommendation, please share the link.
And it states:
AP-Manager Interface Configuring the AP-manager interface on the same VLAN or IP subnet as the management interface results in optimum access point association.

Prime Infrastructure to manage WLC 5760 with IOS XE 03.03.03

Hi there Is IOS XE 03.03.03 on WLC 5760 to be managed via Prime infrastructure 2.1 or what version do I need? It seems to be not fully supported with 2.1... Thanks and best regards Dominic

Hi Dominic,
The release notes http://www.cisco.com/c/en/us/td/docs/net_mgmt/prime/infrastructure/2-1/release/notes/cpi_rn.html#pgfId-43893 show support of up to 03.03.02
I have got a 3850 WLC running on IOS XE 03.03.03 managed by Prime 2.1
The release might not be up to date. When the release notes for Prime 2.1 came out, the highest supported is 03.02.03 and a few days later got changed to 03.03.02.

Guest wireless with WLC 2504, Catalyst 4510R+E and ASA 5510

I need to add guest (internet only) wireless to our existing internal wireless and am looking for advice as to the best practice configuration. Existing infrastructure as follows:
WLC 2504
1142 LAPs
4510R+E
ASA 5510
Existing configuration as follows:
WLC management interface and APs addressed on the 192.168.126.0 /25 network
Internal WLAN mapped to the management interface
Management interface VLAN ID 0 (untagged) and dynamic AP management enabled
WLC port 1 (only) connected to 4510 via trunk with native VLAN set to 7 and allowed VLAN set to 7
4510 connected to ASA inside interface (security level 100)
Switchport on 4510 connected to ASA configured as switchport access VLAN 99 (our internet VLAN)
ASA inside interface NOT configured for subinterfaces and is addressed on the 192.168.121.0 /25 network
What is the best way to add guest wireless to our existing configuration?
Note: I need the guest wireless to be filtered by Websense as our internal wireless is
Any advice would be greatly appreciated!

Thank for the reply Scott. The configuration recommendations from Yahya did not work. I set up as he recommended and also added a dhcp scope on the wlc. Client gets dhcp but cannot even ping the wlc much less anything else. Yahya stated above to configure port 2 on the wlc to an access port on my 4510. Aren't all connections from the wlc supposed to be trunk links to the switch? Shouldn't I just leave the management interface on the wlc untagged and add a dynamic interface for each wlan and tag it with the approriate vlan id? And then leave the (one) physical connection on the wlc (port 1) connected to a trunk link on the 4510 that allows the required vlans?
Any input would be greatly appreciated...

Adding new switch in my network including Cisco Prime Infrastructure

hi all,
if I connect new switch to my network, can I let Cisco PI to apply a specific template of configuration to this switch automatically?
how can I do that ?
thanks in advance

Hi,
i followed these steps :
SWITCH SIDE
- configured Prime Infrastructure as snmp-server host;
- enabled snmp-traps for linkup and linkdown events globally;
- disabled snmp-traps for linkup and linkdown on non relevant interfaces using the no snmp trap link-status command
PRIME INFRASTRUCTURE SIDE
- under "Deploy/Monitor Deployment" i deployed template "Interface Health" for all the interested switches
- under "Administration/System Settings/Mail Server Configuration" configured my internal SMTP server to make Prime Infrastructure able to send e-mails
- under "Operate/Alarms & Events" click on "Email Notifications" , then on "Switches and Hubs"
- check the "critical" box , insert the destination e-mail address into the "To" field then click "Save"
- check the "switches and Hubs" box and then click Save
As i know is possible to avoid to configure every single not-interesting port on the switches with "no snmp trap link-status" command (it's a bit annoying when you have tens of switches), using Port Grouping configuration on PI but i tried it without success.
Hope this helps.

Prime Infrastructure and WLC 2504 N+1 config syncronization

I've setup 2 cisco 2504 WLC's in a N+1 configuration, before we purchased Prime Infrastructure. Now I'm trying to syncronize the configurations between the two devices in PI. I've setup a configuration group, and it seems using templates will keep the configuration syncronized between the two devices. Is it possible for PI to automatically create the templates based on the current configuration of the device. Plus with PI 2.1 it seems like I have to create a template for every section of the configuration, shouldn't there be just one large template that has all the configurations.

Yes, you should be able to discover templates from the WLC

WLC 2504 in Cisco Prime Infrastructure 1.2

Trying to add Cisco 2504 Wireless Controller, Software Version 7.3.101.0, to Cisco Prime Infrastructure
1.2 (1.2.0.103), License Evaluation, with no success.
When using Discovery, Discovery Job show Credential Errors: "Error occured due to invalid SNMP credential"
When Add Device from Device Work Center I get:
Reachability is "Unknown", Device Type is empty, Collection Status is "Managed with Warnings", with message "SNMP Failure: No Response for SNMP Get request.", Collection Time is empty.
I've tried with both snmp v2 and v3.
I've tried to lower "Maximum VarBinds per Get PDU" to 10 or 20, cause I've read similar problem in NCS.

I solved the same problem 5min ago.!
select the device and press syc ..that helped me ...

Cannot add WLC 5508 v7.6.120.0 into Prime Infrastructure 2.1

Hi everyone
Hope you can help us with this issue.
We already configure the WLC using this guide: http://mrncciew.com/2013/02/14/configuring-snmp-on-wlc/
snmp v2: enable
snmp v1: enable
default port values
community: incaenic with ip and mask 0.0.0.0 to allow access from any network or ip
traps receiver: community: incaenic ip: 10.100.100.15
when we try to discover the WLC with the PI it gave the error "SNMP Connectivity Fail"
WLC is on subnet 10.100.102.0/24 and PI in 10.100.100.0/24; there is a Catalyst 3850 between then with no access list on then.
Did someone can guide us with this?
Best Regards.
Alvaro Rugama

Hi,
Which version of SNMP are you using?
If you are using v1/v2 you should be using community string rather than local database credentials?
Regarding the service port what is the ip address assigned on the service port. From the configuration guide "Prime Infrastructure uses the preferred management IP address from the loop back interface. If the device does not have a loopback interface, Prime Infrastructure uses similar logic to the OSPF algorithm to select the router’s preferred management IP address."
Hope that helps.

Prime Infrastructure 2.0 Collection Failure for WLC 5508

Hi,
We have installed prime infrastructure 2.0 as a VM.
I added 2 WLCs (AIR-CT5508) in the device work center.
Both the WLCs are showing as "Managed" but under the collection status it says "Collection Failure".
When I hover over the message it reads:
Other Error: Wireless Controller added successfully but some tables had their records dropped as their key fields failed validation"
Any ideas?
Thanks

Hi Satyaki,
Try to reboot the WLC ,if possible and then check the status of the issue.

Hallo Bastian,
I think you still have browser issue, Using IE is still the best with Prime.
I have exactly same prime 2.2 and installed fixes/software/device packs.
I have no problem I can see all views. I use now IE 11, with Chrome 42.0.2311.90 and firefox 37.01 I have problems too with lots of views. You have not tell what browser + version you have.
Since you have same prime 2.2 as me. I have other problems, can you check yours?

Cannot add WLC 5508 to Prime Infrastructure 2.1

Regards,
I've been migrating / implementing a WCS to PI 2.1. I had several problems at first to add the 11 WLC we have to PI which I could be solving by trying and testing as I have not found many references by Cisco when it comes to troubleshooting when deploying PI.
I have several queries:
1. The WCS was added 11 WLC using different SNMP communities are configured on each of them. At first when trying to add the WLC had PI SNMP communication problems. I performed the test to eliminate any of the WLC added to WCS and add it again with some communities already existing R / W without any problem. At the end, I could not add the WLC so I had to create an SNMP community with the IP of Prime in the WLC so that they can be added. Does anyone know what is the cause of this?
2. I could not add a WLC 5508 IOS 7.3 using this method, even creating an SNMP community and IP mask 0.0.0.0 / 0. No access list or FW in between the WLC These WLC are spread over several countries but i was able to add the other WLC adding a community in each WLC pointing to the IP of Prime. It is similar to this case:
https://supportforums.cisco.com/discussion/12232506/cannot-add-wlc-5508-v761200-prime-infrastructure-21
Thanks for the help.

It turns out that this situation was caused by a bug in 7.6.120.0 (CSCuo73572).
TAC handed me an escalation image (7.6.120.16) that fixed this.
Added the controllers sucessfully on the first try.

Cannot add WLC 5508 7.2.111.3 to Cisco Prime Infrastructure 2.0

Though the Cisco Prime Infrastructure Compatibility Matrix list out that 7.2.111.3 is supported for PI 2.0
I am not able to add the controller to the PI 2.0.
The Reachability Status always shown "Unknow" and SNMP Status always shown "No response for SNMP Get".
There is no firewall between the WLC and PI.
And ping test shows it is reachable.
If I try to add controller by non-management port (I know it is not work but I want to try the reachability), the Reachability Status shown "Reachable" but the SNMP Status always shown error.
And if I use some SNMP testing software to test the SNMP port. SNMP can be quoted.
I have try to lower down the "Maximum VarBinds per Get PDU" but no luck.
Any thing I can do to troubleshoot the problem?

Yes, I follow the procedure but it does not work.
Another update:
I add another WLC with version 7.0.98.0. It is fine.
And I setup another new PI 2.0 and new temporary WLC5508 with 7.2.111.3 to test. It work fine also......
So, I am wondering the existing 7.2 WLC have problem in responsing the SNMP Get. But I dont have any idea to test....
Do anyone have idea to test the snmp connection between PI and WLC?

WLC 5508, Prime Infrastructure, 7921 phones and QoS

Hi everybody!
I have deployed about 50 wireless cisco phones int the network with 27 APs with the WLC 5508.
I'm trying to investigate phones behaviour (I have some loss of audio).
And I use Prime Infrastructure for monitoring.
I run the Voice Diagnostic on the selected two phones.
and in the Charts I see the next:
1. for one phone "Downlink AC Queue Usage" shows all the traffic of "voice packets". but "Uplink AC Queue Usage" shows all the traffic of the "Best efforts packets".
2. for the second phone "Downlink AC Queue Usage" shows all the traffic of "Best efforts packets". and "Uplink AC Queue Usage" shows all the traffic of the "Video packets".
that is strange, very strange. the WLAN of these phones uses platinum QoS. none of other WLANs uses "gold" QoS.
does this mean I have a QoS misconfiguration?
where may the failure be? WLC? switches? router?
please, any suggestions...

I noticed few misconfigurations as per your response
1. Are you configured AP as FlexConnect ? If not AP connected switchport should be configured as ACCESS port & trust DSCP. If it is configured as FlexConnect, then you can configure switchport as turnk & in that case you have to trust CoS using "mls qos trusct cos" command.
2. WLC connected trunk ports always to be configured to trust CoS not DSCP. Otherwise WLC set QoS value ignored by your switch.
3. If you WLAN is set for Platinum then you have to configure Platinum QoS profile for 802.1p & set value as 6.
I would suggest you to verify QoS value preserve across you switch network. You have to take some wireshark packet caputres (as shown in my reference link) and make sure your voice packet DSCP goes into rest of your network as EF. You need to do this for upstream & downstream (from 7921 perspective) traffic. Here is the traffic flow if AP connected to switchport 1 & WLC connnected to switchport 2.
7921 <-> AP <-> Switch port 1 <-> Switchport 2 <-> WLC <-> Switchport2 <-> Rest of your network
Once you do this, then you can go to Prime & check those charts to reflect QoS values correctly. Otherwise you do not know where these QoS value get stripped/or modified in your network.
