X770 MGMT port not working

X770 MGMT port not working

I have configured MGMT port on Extreme X770, following the recommendation from EXOS document, however, 1 out of 6 switches does not work.

The issue is that,it seems the MGMT port does not send or receive any package at all. when outside pings the MGMT port, it does not response the ARP message. when MGMT port pings out, there is no ARP message. and it shows timeout finally.

we have tried to swap cables. it did not work. we have changed the remote side, Cisco, even another extreme X770, still not working.

Has anyone experienced this problem. what should I do ?

Thanks

I believe you're going to need to open a case with GTAC to get an RMA processed.

Default route has been configured:

The port is active:

It looks like a cable issue as there is no incoming package. but we have tried swapping cable, still exactly this port has issue.

Hello Kang,

Is the port linking up? Have you configured a default route for the management vr?

Hi Kang,

Do you mean that the MGMT port of one switch is not working and rest of 5 switches are working well?
If the MGMT port of the switch was still failed to work even when using same cable and peer switch that were normal with other rest of switches, then it can be a HW problem on the MGMT port of the switch.
But if the MGMT issue is seen on all 6 switches commonly with same condition, you would need to check the common information further (e.g. SW version, HW revision, etc.)
