LLDP Nei on only 2 of 3 MAD links

  • 1.  LLDP Nei on only 2 of 3 MAD links

    This strikes me as odd:  I have a 3-chassis 10508 setup, with 1-2, 2-3 and 1-3 IRF and MAD links.  As I brought these MAD links up I checked lldp neighbors and got these (and corresponding log entries:

     

    [rsdcore2]dis lldp nei list

    System Name Local Interface Chassis ID Port ID
    rsdcore2 GE1/2/0/19 b8af-6763-6b56 GigabitEthernet2/2/0/19
    rsdcore2 GE1/7/0/19 b8af-6763-6b56 GigabitEthernet3/7/0/19

     

    But my third MAD link, Gi2/6/0/43 to Gi3/2/0/19 doesn't show up.  Looking at lldp status on the 'good' and 'bad' ports shows the same status:

     

    [rsdcore2]dis lldp status int gi2/2/0/19
    Port 1555 [GigabitEthernet2/2/0/19]:
    Port status of LLDP : Enable
    Admin status : Tx_Rx
    Trap flag : No
    Polling interval : 0s

    Number of neighbors: 0
    Number of MED neighbors : 0
    Number of CDP neighbors : 0
    Number of sent optional TLV : 23
    Number of received unknown TLV : 0

    [rsdcore2]dis lldp status int gi2/6/0/43
    Port 1771 [GigabitEthernet2/6/0/43]:
    Port status of LLDP : Enable
    Admin status : Tx_Rx
    Trap flag : No
    Polling interval : 0s

    Number of neighbors: 0
    Number of MED neighbors : 0
    Number of CDP neighbors : 0
    Number of sent optional TLV : 23
    Number of received unknown TLV : 0

     

    Anyone have a clue before I open a support case?  (and where the heck is the page to list my open support cases???  ;^)

     

    Thanks - Paul
