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

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?

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.

Thanks Everyone  supporting me

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