Hi,
We are using CISCO 2800 series router and cisco 3560 Catalyst Switch for WAN connectivity in a private network.
1. CISCO 2800 router is connected with WAN
2. And Switch is connected after router for LAN connectivity.
From router we are able to ping all private IP's of other networks ,but from switch its creates problem .Sometime we are bale to ping all private IP's from switch and sometime switch misbehaves and not able to ping IP's from switch.
In this we configured two vlan one is default and other is VLAN 10.
Regards
Ravi
