The problem is that afffected Vlan PC not pinging and they are not able to communicate with the network printer and other pc also..

but when i change the ip address of that pc in same vlan, they work for some time...but after that same problem apear..

(ii) The configration of both the Core Switch and workgroup switch ..not altered from last four years..even i checked that complite.

& when i ping that PC from my coreswitch 8540 , its give me time extended message..But when i ping the gateway of Vlan its working fine...but problem in PC & printer.

check the gateway configured on PC and printer...

which vlan you have created and what type of routing you have configured to reach printer on core switch.
