The following table describes the labels in this screen.
8.3.3 802.1Q Static VLAN
Use this screen to configure and view 802.1Q VLAN parameters for the switch. You can
dynamically have a port join a VLAN group using GVRP, permanently assign a port to be a
member of a VLAN group or prohibit a port from joining a VLAN group in this screen. Click
Static VLAN in the VLAN Status screen to display the screen as shown next.
Table 16 802.1Q VLAN Port Settings
LABEL DESCRIPTION
GVRP GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a
way for switches to dynamically register necessary VLAN members on ports across
the network.
Select this check box to permit VLAN groups beyond the local switch.
Port Isolation Port Isolation allows each port (1 to 8) to communicate with the CPU port and the
shared GBIC ports (9 to 12). The isolated ports (1 to 8) cannot communicate with
each other. However, the shared GBIC ports (9 to 12) and the CPU port can
communicate with all ports. This option is the most limiting but also the most secure.
Port This field displays the port numbers.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this
row first to set the common settings and then make adjustments on a port-by-port
basis.
Note: Changes in this row are copied to all the ports as soon as you
make them.
Ingress Check If this check box is selected for a port, the device discards incoming frames for
VLANs that do not include this port in its member set.
PVID Each port on the switch is capable of passing tagged or untagged frames. To forward
a frame from an 802.1Q VLAN-unaware switch to an 802.1Q VLAN-aware switch, the
switch first decides where to forward the frame, and then inserts a VLAN tag
reflecting the default ingress port's VLAN ID, the PVID.
The default PVID is VLAN 1 for all ports, but this can be changed to any number
between 0 and 4094.
GVRP Select this check box to permit VLANs groups beyond the local switch on this port.
GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a
way for switches to register necessary VLAN members on ports across the network.
Acceptable
Frame Type
Specify the type of frames allowed on a port. Choices are All and Tag Only.
Select All to accept all frames with untagged or tagged frames on this port. This is the
default setting.
Select Tag Only to accept only tagged frames on this port. All untagged frames are
dropped.
VLAN
Trunking
Enable VLAN Trunking on ports connected to other switches or routers (but not
ports directly connected to end users) to allow frames belonging to unknown VLAN
groups to pass through the switch.
Apply Click Apply to save your changes to the switch’s run-time memory. The switch loses
these changes if it is turned off or loses power, so use the Save link on the top
navigation panel to save your changes to the non-volatile memory when you are done
configuring.
Cancel Click Cancel to start configuring the screen again.
