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.
