Remove TRUNK port

Hi

have some trouble to remove an existing port from link-aggeration/trunk configuration

show trunk

Configured trunks:

Trunk ID: 5

Hw Trunk ID: 1

Ports_Configured: 6

Primary Port Monitored: Individually

Ports   PortName Port_Status Monitor Rx_Mirr Tx_Mirr Monitor_Dir

1/1/5   none     enable      off     N/A     N/A     N/A

1/1/6   none     enable      off     N/A     N/A     N/A

1/1/7   none     enable      off     N/A     N/A     N/A

1/1/8   none     disable     off     N/A     N/A     N/A

#trunk ethernet 1/1/5 to 1/1/10

#config-trunk-ind

#disable ethernet 1/1/8

#no trunk ethernet 1/1/8

Error - Please provide all (6) Lacp Trunk Ports

#show link-aggregate

System ID: 748e.f8e7.f21a

Long  timeout: 90, default: 90

Short timeout: 3, default: 3

Port 

1/1/5       1        1     10000   Yes   L   Agg  Syn  Col  Dis  No   No   Ope

1/1/8       1        1     10000   Yes   L   Agg  Syn  Col  Dis  Def  No   Dwn

interface ethernet 1/1/8

Error - cannot configure secondary ports of a trunk

It is not possible to configure an individual port or remove an existing from a trunk on an ICX 6650

any ideas ?

Thanks a lot

Re: Remove TRUNK port

This might be to late. You have to go under the main interface of the trunk group. from threre you can turn off the link aggregate. 

int e 1/1/5 
link-aggregate off
exit
Then go under the interface you want to remove. 
inter eth 1/1/8
no link-aggregate configure key 10000 (the key you assigned to the link aggregate.)
Then remove the rest of your settings.
no link-aggregate configure timeout long
exit
Go under each port in the link aggregate and turn it back on.
int e 1/1/5 
link-aggregate active
1/1/6
link-aggregate active
1/1/7
link-aggregate active
 
That should be it. I haven't found another way to remove a port from a link aggregate. 
 
Hope this helps someone. It wasn't easy to figure out.

Re: Remove TRUNK port

It will not allow one to remove trunk/LACP configuration when the trunk/LACP is deployed or active.

First use trunk-config-indepent to disable the interfaces of the trunk before making the configuration change, you can then "no link-agg active" or " "no link-agg config key xxxxx" to effect the change of the trunk.

After you make the modification, you can enable the interface to bring up the new link-agg config.

 

 

Below is the step by step on a TurboIron switch as an example, would be the same for ICX6650 in 7500x code, you have to repeat this fo other switch of the LACP links.  In 8.0x code the link-agg is changed to LAG and it will be out of the scope of this discussion.

( In the below example it is removing e 23 from a 4 port LACP that consisted e 21 to e 24; you will remove e 1/1/8 in your setup of LACP e 1/1/5 to 1/1/8)

 

 

On Switch 1:

Repeat the above for Switch2 on the other end of the LACP links.

Re: Remove TRUNK port

saschaE,

 

Any updates, did you get the port removed from the trunk?
