Trunk EXOS switch to a Cisco switch

[gonzoessex]

Hello,

I've worked with Cisco switches for years and never used an Extreme switch before. I have to trunk one to our Cisco network so have a Cisco switch and Extreme switch in a GNS3 lab.

I have had no luck getting a dot1q trunk working. I have the 2 switches connected and a workstation plugged into either switch.

I want to use to start very basic:

VLAN 100 (sales)
Native VLAN 999


Cisco
VLAN 100 IP should be 172.16.1.250/24

Extreme
VLAN 100 IP should be 172.16.1.251/24
Trunk should be on port 12
Workstation in port 1 in VLAN 100

Can someone help with the Extreme config?


Thanks

Could you show us from Cisco running config how is the IP address on it configured at the moment?

BTW 'show fdb' command also lets you to display just per-vlan forwarding database ('show fdb vlan ').

Interesting:

code:

Extreme-SW1.22 # show fdb port 12

Hmm.. please try 'show fdb port 12' and you will see in what VLAN you see a MAC adress of a Cisco switch. If it's in VLAN 100, it should be there with VLAN 100 mentioned if you wish to see both of them in 100.

[gonzoessex]

Already added that, but same issue.

[Tomasz]

On Extreme you got IP address on a VLAN 100, for that I suppose you have to configure GigabitEthernet3/3 with trunk allowed vlan 100?
What is your output on EXOS with 'show cdp'?

How is your IP address configured on Cisco? Is it in interface vlan 100?
