Per-Port Static VLAN Configuration Options
The following figure and table show the options you have for assigning
individual ports to a static VLAN. Note that GVRP, if configured, affects these
options and VLAN behavior on the switch. The display below shows the per-
port VLAN configuration options. Table 11-11-1 briefly describes these
options.

untagged VLAN assignment per port.
No No
