Port-channel on Cisco 2960 not working.

    Posted May 26, 2017 06:11 PM

    Hi there

    I have an AP 225 that I’m trying to get ether/port channel working.

    For some reason the PWR light on the Access point is Orange/Amber and ETH1 is off.  I tried rebooting it and it does turn on green (power) then goes to Orange. Both Ethernet ports do come on and one goes off. My access point is directly connected to a Cisco 2960 switch with poe+. Can someone help? This is urgent. Thanks

    You need to have LLDP enabled on our Cisco interface. That is the way the AP negotiates POE+ with the switch..

    Hi there
    What is the correct commands? I used lldp receive and transmit. Thanks

    Please execute:

     

    show ap debug system status ap-name <name of ap> | begin "Power Status"

     

    That will tell us what power was negotiated...

    Unless I missed it, you didn't show the output of the Aruba command above.  Quite frankly, if it doesnt negotiate high powered POE, it will not bring up the second port and anything you are trying to accomplish with LACP will not work.

    Ok.  We have to fix the power situation first:

     

    Operational State          POE-AF: One Ethernet port disabled; USB port disabled                                                                                        ; 1x3 chain for 2.4GHz; 3x3 chain for 5GHz

    Current HW State           POE-AF: One Ethernet port disabled; USB port disabled                                                                                        ; 1x3 chain for 2.4GHz; 3x3 chain for 5GHz
    LLDP Negotiated POE Power  13.0W

    It seems like the switch is only negotiating 13.0 wats of power via LLDP.

     

    Please see the comments in the post here:  http://community.arubanetworks.com/t5/Controller-Based-WLANs/AP-275-is-coming-up-with-I-Flag/ta-p/185972 to see if it can give you any ideas.

    I tried that and ran this on my Cisco 2960 that connects to the Ap 225.

     

    lldp run

    int g x/x/x

    power inline static max 30000

     

    Now both links wont come up (after a disable, renable).

       just wanted you to know I finally got it working. Yes it was the ios version on the cisco 2960-s. Weird that it would do that. Cisco tech support was useless and offered little to no help.

    Posted May 30, 2017 11:33 AM

    So thanks to Colin for pointing in the right direction I was able to figure this out. We are a college is cisco proprietary on our network infrastruture. Our Aruba APs range from the 205 to 225 with our controllers being 7210s.

        So what we had to do was a few things. We heard that the aps required 30w and that the cisco 2960 switches only sent out 15w (unless you speficially tell it). Combine that with an ios that didnt allow for proper poe distribution, it only allowed for one link to work in a etherchannel environment (lacp, lldp).

       So this is what I had to do

    Each interface that had an Aruba 225 required port-channeling. To do I checked the ios and if it wasnt the latest version I upgraded was to c2960s-universalk9-mz.150-2.SE10a. Almost immediately the links started working. Weird huh?

    The configuration for each link and the port-channel follows. I made sure the links were shut down prior to the change and then reenabled them and voila they now work. Before this I never saw the ports with "bndled" on them. Now it is showing and works fine. I hope this helps someone out there. :)

     

    Configuration:

     

    SSWC-ER-1#sh ru int gi1/0/1
    Building configuration...

    Current configuration : 165 bytes
    !
    interface GigabitEthernet1/0/1

     spanning-tree portfast
     channel-group 2 mode active
    end

    interface GigabitEthernet1/0/2
     switchport access vlan 1722
     switchport mode access
     power inline static max 30000

    end


    Current configuration : 84 bytes

    interface Port-channel2
     switchport access vlan 1722
