VLAN C ONFIGURATION
3-193
• GARP Join Timer
15
– The interval between transmitting requests/
queries to participate in a VLAN group. (Range: 20-1000 centiseconds;
Default: 20)
• GARP Leave Timer
15
– 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
15
– 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:
Hybrid)
- 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. 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.
• Trunk Member – Indicates if a port is a member of a trunk. To add a
trunk to the selected VLAN, use the last table on the VLAN Static Table
page.
15. Timer settings must follow this rule: 2 x (join timer) < leave timer < leaveAll timer
