Logs showing loop on uplink ports only

Logs showing loop on uplink ports only

On almost all of my network closets I am getting:
Slot-1: [CLI:Voice-Vlan:3] LOOP DETECTED : 94547 transmitted, 935607 received, ingress slot:port (1:49) egress slot:port (1:49)

It always shows the vlan we use for ip phones and the uplink ports. Only difference is sometimes it shows CLI:Voice-Vlan:2 instead of CLI:Voice-Vlan:3.
We have ELRP setup on all ports with 1:49 and 2:49 uplinks excluded. Those are setup in a LACP LAG, which for many of the switch stacks quit working and won't reconnect.

Is there anyway to find out what other port or ??? is causing the loop? Bandwidth isn't an issue on any of the switches. All are less than 1% so there isn't any network storm.

If it is showing the same port ingress and egress then you need to follow the path. This is assuming ELRP is configured on the entire network.
