ELRP ingress port = egress port

[eyeV]

Hi everybody!

I configured standalone ELRP-client on my SummitStack (two x480). So, after a couple of days I saw strange log messages...

ELRP.Report: Slot-1: [CLI:Default:2] LOOP DETECTED : 35590 transmited, 23 received, ingress slot:port (1:7) egress slot:port (1:7)ELRP.Report: Slot-1: [CLI:Default:2] LOOP DETECTED : 35550 transmited, 5 received, ingress slot:port (1:4) egress slot:port (1:4)It happens periodically, but only on stack. I have nine standalone x480 switches and ELRP works correctly on it. I've never seen this situation on it at any rate.

Can anybody suggest me something?

The phone will still be powered by the switch but could have its data connection disabled by ELRP. Are you sure that's not what you're seeing?

Ok. Thanks for this hint!

there must be loop .
could you trace it down by following below steps
1.see what devices are conencted to 1:4 and 1:7
2.If it is a switch ---run elrp on that switch to indentify the loop.
Most possible cause are phones connecting to edge swicth are looped back within the ports in phone.
Have seen this problem for the past 10 years.
if you find thats the issue.
then the remedy on edge switch is to enable bpdu-restrict /edge safegurad features.
