one SVI which is configured HSRP showing both active state on the Nexus F3 A and Nexus F3 B.

Just wanted to ask if you encountered one SVI which is configured HSRP showing both active state on the Nexus F3 A and Nexus F3 B.

These symptoms suggest that the two switches are not seeing each other at layer 2. There are a few things that you might try to do to investigate this:

- does show cdp neighbor on each switch show the peer switch as a neighbor on this vlan?

- can you ping  the other switch interface ip address?

- if ping is successful then does the output of show arp for that IP address have the correct MAC address for the other switch?

- does show cdp neighbor on each switch show the peer switch as a neighbor on this vlan?

Ans: I do not see cdp neighbors on the two switches for VLAN3809

- can you ping  the other switch interface ip address?

Ans: I can ping the other switch interface IP address

- if ping is successful then does the output of show arp for that IP address have the correct MAC address for the other switch?

Mac address output on show ip arp and show int VLAN3809 is different. (0000.0c9f.fee1 / 04c5.a4e8.e6c4)

QMS-BRC-N7010-F3-INSIDE-A# show ip arp | include 10.90.250.73

Thanks for the information. It is interesting that you do not see CDP neighbors on that vlan. Do you see CDP neighbors for other vlans on these switches? 

Can you post the output of 

show ip arp | include 10.90.250.74

on both switches?

Solution is that I delete the VLAN and SVI then reconfigure it again

[Richard Burts]

Thanks for letting us know that the solution was to delete the vlan and svi and then configure it again. I am glad that you found the solution.
