Hi,

The Driver associated with a Cisco Nexus N9K-C93240YC-FX2 is CISCO-NEXUS but for a Cisco Nexus N9K-C93360YC-FX2 it is the GENERIC driver:

I know i can solve the probleme using "Custom Attributes" but if there is another way ...

Thanks,

Hi,
the problem is on a nexus 93240 but not on nexus 93360 with similar configuration ... very strange.

Hi,

I have a problem with the topology.
There are three links between two nexus 93240, 10.60.3.3 and 10.60.3.4:

a port-channel (VPC Peer-Link) whith 2 links:

The link "10.60.3.4:Ethernet1/6" is wrong :
10.60.3.4# sh int et 1/6
Ethernet1/6 is down (XCVR not inserted)
admin state is up, Dedicated Interface
...

This interface on 10.60.3.4 never was up.

No link between ports Ethernet1/48

The stange link appear whith STP topology.

I tried to delete the two nodes but no change.

With another infrastructure, if the root bridge is connected thougth the fisrt Nexus, the ghost link on eth1/6 appear on it.

1859.f582.adff is the MAC address use by 10.60.3.4 for level 3 interfaces (used for STP topology ?):

10.60.3.4# sh int et 1/48 | i add

I do not understand what is happening.
