I have a cisco 3560 connected via fiber to a Nortel 1612G. The connection is up/up, the Vlans on the switch work as needed, but I can not ping the switch from the nortel, and as a result I can not remote into the Cisco for management. I see in the configuration for the trunk that it is configured for a native vlan, but I dont see it defined which vlans are allowed, could this be the issue? I will provide some of the config information for the cisco side, I understand the issue may be on the nortel end but could someone tell me if the cisco part looks ok?
Port config for the trunk:
interface GigabitEthernet0/49
description port_6_1612G
switchport trunk encapsulation dot1q
switchport trunk native vlan 120
switchport mode trunk
Native vlan config:
interface Vlan120
ip address 172.16.120.11 255.255.255.128

Hello David,
You are not performing any pruning on the cisco switch side, so all vlans should be allowed.
Make sure the Nortel side has as the native vlan 120, okay?

Thanks for the reply JCarvaja, I will have to figure out how I can see that information from the nortel side, I am only able to bring up the command line on the nortel and have alot to learn about the command structure.
