Mar 14th, 2010

Hi,

I am facing problem with cisco catlayst 2960 switch

cisco catalyst with ios ver 12.12(52) SE  is  configured 3 vlans (1,200,100) .Siwtch port gigabit Ethernet 0/24  is configured as trunk  connecting the cisco 2821 (ios ver 12.4(15) T3 ) gigathernet 0/0 port of the router.

vlan 1(management vlan)-192.168.10.0/24

vlan 200(Data)- 192.168.1.0/24

vlan 100(voice)- 192.168.11.0/24

vlan 200 is configured as native on both switches

when i am configuring any switch port  connecting to PC  under any of the vlan mentioned above ,I am able to ping router from   pc but from router i am not able to ping pc

what can be the reasons for switch behaving like this

I have this problem too.

As Reza said, it could well be firewalls on the PCs. From a PC in vlan 100 can you ping the vlan 200 IP address on the router ? If so this would strongly suggest a personal firewall issue.

Hello Praveen,

Do you have any firewall software installed on your PC that prevents it from being pinged?

Can you try pinging a different PC?

Thanks Everyone  supporting me

It was the antivirus in the PC  which is blocking ICMP packets.
