cisco 3750 switch icmp dealy to default gateway

                   Hai,

I had setup a lan infrastructure with 5 3750 stack swithes. In these 3 of them are in one stack which is acting as access switch, 2 of them in another stack which is as core switch where all the SVI is configured. Now, when i tried to ping from our edge pc which is connected in access switch to default gaeway, which is configured in core switch, the ICMP is getting delayed . But when try to ping from the same edge pc to another user PC, it is getting less tahn 1 millisecond icmp replies.

Anybody please let me know, why icmp is delaying to default gateway , but working with another edge to edge pcs without any delays??????????

cisco 3750 switch icmp dealy to default gateway

Hello Mohamed,

routers and multilayer switches answer to ICMP requests but they do not do this with high priority: they give priority to other critical activities like processing spanning tree messages, routing protocol messages and so on.

What you see should be normal.

Hope to help

Giuseppe
