Nexus 7K VPC with WLC 5508

Does anybody know if VPC is supported with WLC 5508? 

I am running 5.1.(3).

WLC doesn't support vPC. You can configure regular LACP PO which uplink to both Nexus (N7K's PO will be configured as vPC).

Re: Nexus 7K VPC with WLC 5508

would mode "on" also work on the PO from the Nexus to the WLC?

Recommended setting is LACP. On will work if LACP is not an option, but misconfigured PO can cause traffic blackhole.

I'm very confused by jeye comments.

I know for a fact that WLC 5508 does not support " channel-group 1 mode active"


Bottom line, can you connect a WLC 5508 to a pair of Nexus 7000 using vPC ?

If yes, can I use the following command to setup vPC on each Nexus ?

interface Ethernet1/1

  switchport

  switchport mode trunk

  switchport trunk native vlan 100

channel-group 1 mode on

  no shutdown

interface port-channel1

  switchport

  switchport mode trunk

switchport trunk native vlan 100

  vpc 1

Thank you

That is fine on the Nexus side.

What I am saying is, WLC will not have the "vpc" command option. All you can do is regular port-channel.

hi,

its absolutely possibe.

1. ensure you  enabled LAG on WLC

2. Assign 0 as vlan id on management interface (untagged), assuming u only hav management interaface.

if u have other AP manager interface then configure vlan id as 0 for those int also.

3.in both nexus,configure portchannel with vPC, assign it on physical interface(same as wht u hav mentioned above)

it should work if you follow the above procedure.

because i am having 2 no of 5508 and 2 no of nexus 7010, the above setup works fine.

But how do you enable port-channeling on the actual 5508?

Does it automatically bundle all uplink ports?

I know with the 7ks all configs have to match or else it won't bring up the port-channel.

I haven't worked with the WLC 5508 but from the configuration guide you need to enable LAG and reboot the device -

Yeah I understand how to do that part and have it enabled already. I just thought there would be more to it on the 5508 since its an appliance. Even though its not a switch IOS persay I was thinking it would still port-channel the same as a switch.

Thanks
