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
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.
Do you have any firewall software installed on your PC that prevents it from being pinged?
Can you try pinging a different PC?
