Fabric, mac move, no ping

Alexandr_P — Mon, 10 Aug 2020 14:57:50 GMT

Hello!

Below scheme:

All works fine.

BUT, when access switch (X590 #1) connect to VSP#2 ping between lap-tops is disappear and does not renew.

Interesting that all ports are deleted from VLAN 1, but:

VSP7K#2_LAB:1#sh vlan mac-address-entry mac 64:31:50:0e:7c:a7

“64:31:50:0e:7c:a7” - MAC address of lap-top in VLAN 10

port Port-1/1/4- to X590 #1

Port-1/28 - NNI

Any ideas?

Thank you!

Disconnect the 590_1 and laptop from the network.

Next, move the laptop to the x440. Setup some pings between the laptops and switches.

If everything is stable reconnect the 590_01 to the network and watch the logs. I suspect you have a duplicate IP address or a simple misconfiguration somewhere.

Hello, Paul!

Moved lap-top to X440 and no pings.

And one more time I see transferred MAC on VLAN 1 (but VLAN 1 didn’t even configured on these ports)

MAC of lap-tops:

lap-top 1 = 64:31:50:0e:7c:a7
lap-top 2 = 00:1e:68:1b:68:20

May be it could be issue with channelization?
