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.
