Recently I have been looking into the different etherchannel modes.
LACP
Active – Active negotiating state
Passive – Passive negotiating state
PAGP
Desirable – Active negotiating state
Auto – Passive negotiating state
On – Forces an interface into an etherchannel without LACP or PAGP.
For the exchange of packets to take place, you must have one of the below modes.
LACP
- Active – Active
- Active – Passive
PAGP
- Desirable – Desirable
- Desirable – Auto
