Issue with downlink ports in Cisco Catalyst 9500-48Y4C switch - Page 3

jshayne · ‎02-16-2023

I connected a computer with a 25G interface in Cisco Catalyst 9500-48Y4C switch. I saw ports on both PC and the switch are UP (green light). However, the switch could not learn the computer's MAC address. Also, the computer did not know the MAC address of the connected switch port. It seems to be a layer-2 problem. When I tried the ping from the computer to the switch port, as the MAC address of the switch port is not listed on the computer, the broadcast messages were sent out. But what surprised me is that switch still received the broadcast messages from the computer. What is the problem here?

-------------On the switch---------------------

When I ran "ping 123.123.123.123" from the computer, the switch port updated broadcast messages:

@MHM Cisco World

For the command:

show platform hardware fed active fwd-asic abstraction print-resource-handle  0x7f356443be98

I mentioned in the previous post that I got the error "[Interface Resource Pointer] not valid handle when I followed your suggestion.

Maybe could you please point me out how to run this command properly?

switchport access vlan 1
switchport mode access

there is no VLAN assign to port,
after add two command above shut/no shut

balaji.bandi · ‎03-12-2023

maybe I lost here, but as I mention this looks to me like more of a compatibility issue (have you contacted the NIC vendor to troubleshoot with you (or contacted Cisco TAC for the correct answer if the code has any BUG?)

As per the OP, the ports are Layer 3 and trying to get my head around - why do we need to access port config by default if the ports do not belong to any VLAN, cisco default vlan1?

@MHM Cisco World @Leo Laohoo @balaji.bandi

I just updated the switch firmware. The problem remains the same. It is really weird to me.

show version
Cisco IOS XE Software, Version 17.06.05
Cisco IOS Software [Bengaluru], Catalyst L3 Switch Software (CAT9K_IOSXE), Version 17.6.5, RELEASE SOFTWARE (fc2)

balaji.bandi · ‎03-07-2023

i do not think this is issue with Switch for now. since you not able to see MAC address on the ports, this is more of compatable issue.

either change the card with tested one or contact NIC vendor for the support

Since you tested PC to PC with same cable working, you can also test switch port to switch making as layer 3 ports and see if that works. and contact NIC vendor again.

@balaji.bandi @jshayne
Mr.Balaji ask why assign VLAN1 to port if the port by default is assign to VLAN1.
that totally right
but let me explain some point here,
first @jshayne mention that he face issue of mac not dynamic learn to mac table, the mac table have fields
VLAN-MAC-Port
MAC of PC connect
Port where the PC connect to SW
VLAN must configurable

he also mention that he try L3,
then I think that he change the port to L3 which not work then return to L2, and still port not work.
so I start ask him share some output like fed active ifm if-id,
and I was right the L2 port subblock missing which indicate that the port is not run as L2
then show siwtchport interface he share show that L2 is enable, which show that port is not run as L2
but I sure that issue is from L2 port character,
so I finally ask him share show platform pm
and it give me indicate why port not run L2 port (if I am right), the show platform pm show that the port dont have VLAN1 assign to it.
so I suggest assign again VLAN1 to port.

from where this issue,
the SW to be fast the load must distribute from run all in CPU into Card module.
so the port status and character is show in different places, in CPU FED and ASIC.
so sometimes because of
1- BUG <<- that will confirm from TAC
2- the SW not complete and right initialize the port when reboot <<- but he reboot twice I think after upgrade firmware
3- there is Hardware failure in UADP or ASIC of port range <<- I dont think this is issue, because only part of port config is not functional

so it BUG and he need to contact TAC, which I think he already contact then.
Note:- @jshayne please update us after config vlan1 to port.

thanks

@MHM Cisco World I also know that all interfaces are added vlan 1 by default. To confirm, I also tried your suggested commands with vlan 1 configuration on the two mentioned interfaces. The issue still remains the same. I used several hardware switches but never meet this problem before.

MHM Cisco World · ‎03-13-2023

Yes you are correct by default the port is L2 and assign to VLAN1, but here sure there is bug,

jshayne · ‎03-14-2023

Hi @MHM Cisco World I think you are right that there is something wrong with the switch. It is important for me to understand where the bug comes from. Is this the hardware failure? Because as I mentioned earlier, I already upgraded the firmware. With the bug like that, what should I do to fix it? I have already gotten stuck in this problem for a while.
I'm looking forward to hearing from you. Thanks.

If you loop the interface with L3 Interface, is that works on the switch

example :

Switch - port 4 (configure L3)---- (IP 10.10.10.1)

|

Switch - port 5 (configure L3)---- (10.10.10.2)

is the port come up and you able to ping L3 IP each other ?
