    hi,

     

    I have a lot of input errors for 5 ARUBA controllers with portchannel. All ARUBA controllers are connected to Cisco 6500. I am not sure when problem started, but probably after replacing Cisco 6500. Have you some idea, what can be checked or changed ?

     

     

    CISCO SIDE

     

    basic info

    cisco WS-C6509-E
    Version 15.1(1)SY1


    All interfaces which are connected to ARUBA have types - 10/100/1000BaseT

     

    configuration
    interface Port-channel201
     description EtherChan NYKARUBA01
     switchport
     switchport mode trunk
     switchport nonegotiate

    interface GigabitEthernet1/6/5
     description Portchan 201 to NYKARUBA01
     switchport
     switchport mode trunk
     switchport nonegotiate
     no cdp enable

    ARUBA SIDE

     

    basic info

    Model Aruba3600

    Can you make sure that the same VLANs on the Cisco side are allowed on the Aruba side?  I only see allowed VLANs on the Aruba side..

    I added ´´switchport trunk allowed vlan 1,1220,1230,1320,1330-1332,1420-1424´´ on cisco side, but there still input errors on ARUBA side.

    You probably do but make sure you are using Aruba recommended gbics on the controller

    I am using 10/100/1000BASE-T (RJ-45), not SFP.

    I have two customer which have same physical network connection.

    It means that there is Cisco Switch 6500 connected via Port-channel to ARUBA 3600.

    ARUBA 3600 - portchannnel 0 (gi 1/0 + gi 1/1).

    I cleared counters before 6 six days and there is especially a lot of input error in device NYNARUBA01.

     

    Do you think that it is ok, when there is a lot of input errors? or maybe is it normal behaviour ?

    is ARUBA using only LACP protocol ? can I set static port-channel ?

     

    probably I will try to turn off portchannel and I will try connect only one physical cabel.

    If  it is a trunk, please make sure the allowed vlans match on both sides.

    I found root cause. It was STP. I added bpdu filter on CISCO switchports + I denied STP on ARUBA and then input errors on ARUBA interfaces disappeared.
