Newbie: trunk between 6500 and Blade Switch 3020

Hi,

Beeing newbie , I need advice to setup trunk between my 2 switches.

I would like to use 4 ports as TRUNK

On the 6500 , this is what I have done :

set port channel 5/37-40 61

...

set trunk 5/37 auto isl 1-1005,1025-4094

set trunk 5/38 auto isl 1-1005,1025-4094

set trunk 5/39 auto isl 1-1005,1025-4094

set trunk 5/40 auto isl 1-1005,1025-4094

...

On the Blade Switch 3020 I have done :

interface GigabitEthernet0/17

switchport trunk encapsulation isl

switchport mode trunk

shutdown

channel-group 1 mode on

!

interface GigabitEthernet0/18

switchport trunk encapsulation isl

switchport mode trunk

shutdown

channel-group 1 mode on

!

interface GigabitEthernet0/19

switchport trunk encapsulation isl

switchport mode trunk

shutdown

channel-group 1 mode on

!

interface GigabitEthernet0/20

switchport trunk encapsulation isl

switchport mode trunk

shutdown

channel-group 1 mode on

Will that work ?

Could you tell me if I have to put the trunk port on the same VLAN ?

Many thanks in advance for your help.

regards

David

Hi David,

Did you configure your interface Port-channel1 to trunk configuration as follows:

interface Port-channel1

switchport trunk encapsulation isl

switchport mode trunk

no shut

Try this.
