Hello everyone,
I have Cisco Catalyst-XE 6880 connected in a VSS mode and 2960 switches connected in a stack through each stack port-channel is configured
The problem is when I keep Gateway of my core switch I get high latency going towards WAN and when I keep Gateway of Router I get normal latency without any jitter
Also, I can see Cpu utilization on Core switch is this normal or should I raise

Hi,
Can you explain what do you mean when you say:
"I keep Gateway of my core switch I get high latency going towards WAN and when I keep Gateway of Router I get normal latency without any jitter"?
Are you saying, when the VSS is layer-2 only, there is no latency but when it is layer-3 there is latency?
