Hi Tasuka,
By idle timeout, I was meaning same application timeout due no activity.
Cordially

Re: TCP session and ARP aging time out
Gladston, thanks for you reply,
Because I got the router reply ICMP network unreachable when data
want to send, it look like is the router( layer 3 switch) did not
known how to route the packet to destination so reply the ICMP back
to sender, as I remember that layer 3 switch is work to check routing
table once then switch packet in layer 2, but the MAC table has aging
time out in 300 sec. If I am wrong please let me know. and could you
explain the idle timeout ?
Sincerely,
Tasuka
