ACI OSPF neighborship Logs

[OmkarPol52290]

Hey Team,

Is there a way to see logs on the APIC side? for OSPF neighborship. We cannot see in Fault or anything. Does anyone know how to check events?

You need to access the APIC CLI and use one of commands below

<show ip ospf neighbors vrf (vrf|all)> – shows OSPF neighbors of given vrf
<show ip ospf route vrf (vrf|all)> – shows OSPF routes of given vrf
<show ip ospf interface vrf (vrf|all)> – shows ospf interfaces of given vrf
<show ip ospf vrf (vrf|all)> – shows ospf information of given vrf
<show ip ospf traffic vrf (vrf|all)> – shows ospf traffic of given vrf

More comands you can see in this link

Hello,

I'm aware of this but I was wondering if there is something like debugging on traditional IOS.

For neighborship hellos and other stuff.

Hi @OmkarPol52290 

Both NXOS and iNXOS (the version of NXOS running on ACI leafs) keep quite an extensive set of logs, so you rarely need to debug anything like in IOS.

Check these commands (first you need to enter in VSH):

vsh

show ip ospf event-history adjacency
show ip ospf event-history event
show ip ospf event-history lsa
show ip ospf event-history spf
show ip ospf event-history redistribution
show ip ospf event-history ldp
show ip ospf event-history te
show ip ospf event-history rib
show ip ospf event-history hello

If you want to perform the tshoot ACI style, you can always have a look on the ospf_trace files, but in the newer versions the files are binary. You can find them in /var/log/dme/log OR /var/sysmgr/tmp_log

Cheers,

Sergiu
