OK, thanks a lot.

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:

Class=Node
Status=Normal
Node Type=PHYSICAL
Vendor=Cisco Systems, Inc.
Product name=N9K-C93360YC-FX2
System Description=Cisco NX-OS(tm) Nexus9000 C93360YC-FX2, Software (NXOS 64-bit), Version 10.3(3), RELEASE SOFTWARE Copyright (c) 2002-2023 by Cisco Systems, Inc. Compiled 4/30/2023 12:00:00

System Description=Cisco NX-OS(tm) Nexus9000 C93240YC-FX2, Software (NXOS 64-bit), Version 10.3(3), RELEASE SOFTWARE Copyright (c) 2002-2023 by Cisco Systems, Inc. Compiled 4/30/2023 12:00:00

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


Thanks,
Fred

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

Hi,

I don't know where to look ...

If this can help ?

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:
# show interface port-channel 22 | i Members
  Members in this channel: Eth1/49, Eth1/60
- a Keep-alive on eth 1/48


10.60.3.3# show cdp neighbors

1) 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.

2) 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
  Hardware: 100/1000/10000/25000 Ethernet, address: 1859.f582.adff (bia 1859.f582.ae2f)
10.60.3.4# sh int vlan 1 | i add
  Hardware is EtherSVI, address is  1859.f582.adff

I do not understand what is happening.


Thanks.
