SSE-G2252/SSE-G2252P Switches User's Manual
•
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.
