Manual Configuration Commands

– 1018 –

All ports in a trunk must be configured in an identical manner, including

communication mode (i.e., speed and duplex mode), VLAN

assignments, and CoS settings.

Any of the Gigabit ports on the front panel can be trunked together,

including ports of different media types.

All the ports in a trunk have to be treated as a whole when moved

from/to, added or deleted from a VLAN via the specified port-channel.

STP, VLAN, and IGMP settings can only be made for the entire trunk via

the specified port-channel.

Dynamically Creating a Port Channel –
Ports assigned to a common port channel must meet the following criteria:

Ports must have the same LACP system priority.

Ports must have the same port admin key (Ethernet Interface).

If the port channel admin key (

lacp admin key

- Port Channel) is not set

when a channel group is formed (i.e., it has the null value of 0), this

key is set to the same value as the port admin key (

lacp admin key

-

Ethernet Interface) used by the interfaces that joined the group.

However, if the port channel admin key is set, then the port admin key

must be set to the same value for a port to be allowed to join a channel

group.

If a link goes down, LACP port priority is used to select the backup link.
