4.7.9. Port Group Configuration Menu
On the Advanced Switch Configuration Menu, pressing "P" opens the Port
Group Configuration Menu, as shown in Fig. 4-7-29. On this screen, you can
configure port grouping. If a port grouping is configured, ports designated
as members of the port group can communicate only among member ports
in the same group. Multiple port groups can be assigned to each port. An
example of configuration using port grouping is given in Fig. 4-7-28.

(This configuration allows communications between PC1 and Internet, and
among PC2, PC3, and Internet.)
Note: The loop detection/shut-off function detects a loop of a frame and
shuts down the connection, even if the loop occurs between different
port groups.
If some member ports of a link aggregation group are configured
across two or more port groups, a frame may not be transferred
normally.
