Cisco Catalyst-XE 6880 high latency

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 tac case for this

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?
