Link Aggregation on 6200

[Yanesh]

Hi guys

Anyone knows how to configure a link aggregation on a 6200 switch. Actually i have 2 link going to an Alcatel 6850 (layer 3). I have already configure the link agg on the 6850 and allow several vlans to pass through but on the 6200 when applying trunk on the link aggregation ports it dont allow me.

any clues

Hope to get a reply ASAP

any log whats going on? maybe firmware versions of 6200 / 6850?

which ports do you use?

- on a 6200 trunk means 802.1q-Tagging
- port-channel means static LAG
There are 8 predefined port-channels where you have to associate the interfaces:
console(config)# interface port-channel 1
console(config-if)# interface range ethernet g1-2
console(config-if)# description LAG-1
console(config-if)# channel-group 1 mode on

Thanks for your reply Sylvio

i have configured same as mentioned

console(config)# interface port-channel 1
console(config-if)# interface range ethernet g1-2
console(config-if)# description LAG-1
console(config-if)# channel-group 1 mode on

Now i need to pass vlan through this switch. This is where i am stucked. Any clues??

"through this switch" i mean through this link agg to the switch 6850.


thanks

for tagging vlan 100 and 101 on the LAG and no tagging of vlan 1 (= default vlan) try this:
console (config) # interface port-channel 1
console (config-if) # switchport mode trunk
console (config-if) # switchport trunk allowed vlan add 100 (or "all" for all vlan)
console (config-if) # switchport trunk allowed vlan add 101
console (config-if) # switchport trunk native vlan 1
