• GARP Leave Timer* 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 centiseconds
• GARP LeaveAll Timer* 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 centiseconds
• Mode Indicates VLAN membership mode for an interface.
- Access - Sets the port to operate as an untagged interface. All frames are
sent untagged.
- General – Specifies a hybrid VLAN interface. The port may transmit tagged
or untagged frames.
- 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.
Default: General
• 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.
Timer settings must follow this rule:
2 x (join timer) < leave timer < leaveAll timer
