Manual Configuration Commands
– 1216 –
◆
The ports at both ends of a connection must be configured as trunk
ports.
◆
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.
