  1. Rene,

    Hi. With the debug condition there are multiple options that can be used such as interface (as you highlighted) ip address, mac address, etc… When you have multiple debug conditions configured is it a logical “and” or “or”? In other words do they all have to match for it to work with multiple conditions? When using the “ip” condition could that be any IP going through the router? Could it also include traffic to the router itself? Many thanks.

  2. Rene,

    I have been able to get conditional debug to work with interface. However, I have yet to perform a successful conditional debug with ip. Here’s an example:

    R5#debug ip ospf hello
    OSPF hello debugging is on
    R5#
    OSPF-1 HELLO Gi1.45: Send hello to 224.0.0.5 area 0 from 155.1.45.5
    R5#
    OSPF-1 HELLO Tu0: Send hello to 224.0.0.5 area 0 from 155.1.0.5
    R5#
    OSPF-1 HELLO Gi1.5: Send hello to 224.0.0.5 area 0 from 155.1.5.5
    OSPF-1 HELLO Gi1.58: Send hello to 224.0.0.5 area 0 from 155.1.58.5
    R5#
    OSPF-1 HELLO Gi1.45: Rcv hello from 150.1.4.4 area 0 155.1.45.4
    OSPF-1

  3. Rene,

    Thank you for checking as well. Much appreciated.

  4. I tried a couple of different combinations and maybe in GNS3 this command doesn’t work at all.
    I set conditions for completely different IP and only enable debug ip icmp, ping from another router and I still get output.
    enable condition for interface that isn’t used and I still get debug output when pinging.
    Seems this command isn’t working at all in GNS3.

    I’d fire up my rack of gear but it’s 110 here …

    R5#debug ip icmp
    ICMP packet debugging is on
    
    R5#debug condition ip 192.168.1.1
    Condition 1 set
    
    R5#
    *Jun 23 05:13:31.239: ICMP: echo reply sent, src 10.1.3

  5. Hi Daniel,

    Same issue here, conditional debugging works for interfaces but I was unable to get any wanted results with debug ip condition. Tried it in VIRL and on real hardware.
