Configuring Dynamic VLAN Registration
Use the VLAN > Dynamic page to enable GVRP globally on the switch, or to enable GVRP and adjust
the protocol timers per interface.

• “Configuring VLAN Interfaces” on page 380
Parameters
These parameters are displayed:
Configure General
• GVRP Status – GVRP defines a way for switches to exchange VLAN information in order to
register VLAN members on ports across the network. VLANs are dynamically configured based
on join messages issued by host devices and propagated throughout the network. GVRP must
be enabled to permit automatic VLAN registration, and to support VLANs which extend beyond
the local switch. (Default: Disabled)
Configure Interface
• Interface – Displays a list of ports or trunks.
• Port – Port Identifier. (Range: 1-12)
• Trunk – Trunk Identifier. (Range: 1-12)
• GVRP Status – Enables/disables GVRP for the interface. GVRP must be globally enabled for the
switch before this setting can take effect (using the Configure General page). When disabled,
any GVRP packets received on this port will be discarded and no GVRP registrations will be
propagated from other ports. (Default: Disabled)
GVRP cannot be enabled for ports set to Access mode (see “Adding Static Members to VLANs”
on page 724 ).
• GVRP Timers – Timer settings must follow this rule:
2 x (join timer) < leave timer < leaveAll timer
• Join – The interval between transmitting requests/queries to participate in a VLAN group.
(Range: 20-1000 centiseconds; Default: 20)
• Leave – The interval a port waits before leaving a VLAN group. This time should be set to
more than twice the join time. This ensures that after a Leave or LeaveAll message has
been issued, the applicants can rejoin before the port actually leaves the group. (Range:
60-3000 centiseconds; Default: 60)
• LeaveAll – The interval between sending out a LeaveAll query message for VLAN group
participants and the port leaving the group. This interval should be considerably larger
than the Leave Time to minimize the amount of traffic generated by nodes rejoining the
group. (Range: 500-18000 centiseconds; Default: 1000)
Show Dynamic VLAN – Show VLAN
VLAN ID – Identifier of a VLAN this switch has joined through GVRP.
VLAN Name – Name of a VLAN this switch has joined through GVRP.
Status – Indicates if this VLAN is currently operational. (Display Values: Enabled, Disabled)
