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

Oh, works now. 🙂
Please post us the version you are running from the output of 'show version'. Then it might become clear if it was kind of a bug or other uncommon behavior.

Just rebooted the Extreme switch:

Bingo (bug?)

There's not much to it on Cisco:

code:

interface GigabitEthernet3/3
 switchport trunk allowed vlan 100,999
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 999
 switchport mode trunk
 media-type rj45
 duplex full
 no negotiation auto

interface Vlan100
