‎05-21-2023 03:32 AM

We two nexus switch 9k and configured with VPC and HSRP, we have configured three vlan on that three switches. Vlan 2 for CCTV , vlan 3 for Monitering PC and vlan 1 for Dell Server that connected with two 9k switches by port channel.  The two nexus switches is also connected two one distribution switch by port channel. when i do not know how , these two 9k switches are active / active in hsrp when i shutdown one uplink Eth1/2 of 9k1 which is active  then traffic do not move on 9k2. let me correct if my design is okay.

I am 100 % sure that i assigned gateway to Host/server as VIP not ip of vlan svi of nsk1 or nsk2. i assigned gateway ip as vip in host/server.

i am testing this in EVNG environment not in physical.

just give us time, 
NOW 
share 
show route and show ip interface brief <<- after the Link is down 
same time share spanning tree in case of Link UP and Link Down, what is STP mode you use ?

this lab for you 
to see we care and read all your post but time is limit, 
anyway the issue I face and make me late reply is RAM of my PC I can not use four NSK in one LAB 
I use three and two PO on for VLAN10 and other for VLAN20
shut down one link of PO for VLAN10 and you see the ping still success. 
point I mention above can be critical
the SVI of NSK down automatic in case the peer-link down not on one of PO member down
