Change Characteristics of an existing Etherchannel from command line

Answer

Add Adapter to existing Etherchannel

To add an adapter to an etherchannel from the command line you can do the following from the command line:

COMMAND
/usr/lib/methods/ethchan_config -a ent2 ent1

ent2 etherchannel
ent1 adapter to add
-a Flag to use for adding an adapter

This command is just to verify what we have configured before we add ent1 to the etherchannel:

lsattr -El ent2 It only shows ent0 as primary


After we added the adapter we ran the same command to verify what we have after the addition of ent1



Add Adapter as backup to the existing Etherchannel

To add an adapter to an etherchannel as a backup from the command line you can do the following from the command line:

COMMAND:
/usr/lib/methods/ethchan_config -a -b ent2 ent1

ent2 etherchannel
ent1 adapter to add
-a Flag to use for adding an adapter
-b Flag to use for adding as a backup adapter

To verify what we had before we made any changes we ran the following command:

lsattr -El ent2



To verify what we have after we added the backup adapter we run the same lsattr command.



Remove an adapter from an exsisting Etherchannel

To remove an adapter from an etherchannel from the command line you can do the following:

COMMAND:
/usr/lib/methods/ethchan_config -d ent2 ent1

ent2 etherchannel
ent1 adapter to remove
-d Flag to use for removing an adapter

This will only remove ent1 from the etherchannel. To verify what we have before we remove ent1 we can run the following command:

lsattr -El ent2



Now we run the same command above to verify that ent1 has been removed:




Change mode of an existing Etherchannel

To change the mode of an etherchannel from the command line you can do the following:

COMMAND:
/usr/lib/methods/ethchan_config -c ent2 mode 8023ad

ent2 etherchannel
-c Flag to use for changing the mode of an etherchannel

I will change the mode from standard to 8023ad. To verify what we have it set to now run the following command:



Now we run the same command above to verify that the mode has been changed to 8023ad.
