Dear All
We have Core->Distribution Setup ...
At Core Level We have 4500x in VSS mode and at 3850 Stack acting as Distribution Switch for Remote Building , Connectivity between Core & Distribution is 20G etherchannel ( 10G + 10G)..
We have Server Farm Vlans created on Core and User Vlans created on Cisco 3850 Distribution . To avoid STP Loops we have L3 connectivity between Core & Distribution.
We have Issue on Latency when we ping any Vlans SVI ( Gateway ) either at Core or Distribution or vice-versa latency is greater than 1ms ( 2ms or 10ms or in between ) , but if any Server from Core to any User from Distribution or within Distribution or Core itself latency is less than 1ms ,which is ok..
So is this behaviour common for new Cisco 4500X & Cisco 3850 Switches where icmp for any SVI has lower pirority , or do we need to configure something for getting latency less than 1ms....
IOS Version for 4500X :
Cisco IOS Software, IOS-XE Software, Catalyst 4500 L3 Switch Software (cat4500e-UNIVERSAL-M), Version 03.04.00.SG RELEASE SOFTWARE (fc3)

Please revert with comments , as we have seen that in 3750 if we ping SVI latency is less 1ms and Customer is saying same to us. So whats point in going for Cisco 3850 & Cisco 4500X
