Hi, I have a 7606 switch using GBIC fibre connection to the other site switch through SP. Both ports configuration are trunk mode,I can't ping the other site switch SVI from my SVI(both are on the same subnet and VLAN), but SP switch in the middle using SVI can ping our both sides,also I can ping the other site after I replace from 7606 to 2950 with same configuration.
7606 can recieve the arp from the other site switch, but the age is 0. The debug information shows it sent a arp without the opposite mac-address.
no ip address
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 200
switchport mode trunk
ip address 192.168.1.100 255.255.255.0
I hope someone can help me.
