Trunk through 1Mbps

Unanswered Question
Nov 22nd, 2009

Dear all,

I know that  have posted this already before in the WAN Switching forum but I found no proper solution

I have Catalyst 2960 switch and 3560 PoE switch are connected together through a 1M leased line via trunk ports.

I cannot ping from any side to the other with a packet of size 1500 or more, also RDP connection is very slow and usually times out

trunk port of the 2960 is 10/100 and that of the 3560 is Gig.

Please find the Attachment

any advise?

I have this problem too.

Do you have delay between both ends when you ping? Do you have bandwidth utilization?

with 1500 packet size and more, the packet have to be fragmented, the fragmentation can cause delays.

The default timeout is Cisco router/switch is 2 seconds, which means if the delay is larger than those 2 seconds , you will find ... instead of !!!

This doesnt necessarily means the packet is not transmitted at all, it just means there is no reply within those 2 seconds.

Try to set the timeout to some thing larger than 2 , for example 5 and try.
