VLAN C ONFIGURATION
3-157
• GVRP Status – Enables/disables GVRP for the interface. GVRP
must be globally enabled for the switch before this setting can take
effect. (See “Displaying Bridge Extension Capabilities” on page 3-16.)
When disabled, any GVRP packets received on this port will be
discarded and no GVRP registrations will be propagated from other
ports. (Default: Disabled)
• GARP Join Timer
9
– The interval between transmitting requests/
queries to participate in a VLAN group. (Range: 20-1000 centiseconds;
Default: 20)
• GARP Leave Timer
9
– 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)
• GARP LeaveAll Timer
9
– 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)
• Mode – Indicates VLAN membership mode for an interface.
(Default: 1Q Trunk)
- 1Q Trunk – Specifies a port as an end-point for a VLAN trunk. A
trunk is a direct link between two switches, so the port transmits
tagged frames that identify the source VLAN. However, note that
frames belonging to the port’s default VLAN (i.e., associated with
the PVID) are also transmitted as tagged frames.
- Hybrid – Specifies a hybrid VLAN interface. The port may transmit
tagged or untagged frames.
9. Timer settings must follow this rule: 2 x (join timer) < leave timer < leaveAll timer.
