Active-gateway ping or ssh don't work

  • 1.  Active-gateway ping or ssh don't work

    Posted May 10, 2021 10:42 AM
    Hi,
    I have a strange behaviour on 8325 vsx as my active-gateway below doesn't respond to ssh/ping:
    interface vlan 34
    vsx-sync active-gateways
    ip address 192.168.34.2/23
    active-gateway ip mac 12:01:00:00:01:00
    active-gateway ip 192.168.34.150

    the configuration is the same on peer
    from a distribution switch ping/ssh is ok to ip address of both peer
    the arp resolution is ok for the ip active-gateway
    no vrf on the network ...

    What could be the problem, I'm loosing my mind .... the active-gatway funcitonnality would be used for routing for others vlan,
    I must to be sure that's all is ok before plan a migration.

    Does it respond to ping from devices on the same subnet/VLAN?

    HI,
    I made en extended ping from a cisco device by specifying the source address in vlan 34 and it doesn't work.
    I created a second active-gteway for another vlan (with same active mac ) and after that both active-gw were reachable ...?!?
    I deleted the new active-gw and the ping to the acti-gw for vlan 34 doesn't work ....

    I don't understand why .... and this behavior for me seem to be like a bug.
    I think i have to open a tac case.
    Brgds

    I guess the next thing I would check is the L3 path to and from VLAN 34 (routing). I know it doesn't sound like it, but it sounds like something is definitely in play somewhere at L3 or L2 over a trunk. Enabling another L3 interface fixed it, and maybe its reachable through that?

    I understand but how to explain that the ip address of the interface vlan reply to ping and not the active-gateway ip.
    the L2 is ok (arp resolution is ok for both address) and i ping "from" the vlan34 on another switch so no routing process involved.

    Let's see what the TAC reply after investigation....

    Brgds.

    Ahh OK I didn't know you were able to ping the L3 interface. Yea that's strange.

    for me, it is "normal" the SSH can't work on Active Gateway... (but ICMP should work)
