SMC Networks 10/100 manual Vlan Configuration

VLAN CONFIGURATION

•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)

•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)

*Timer settings must follow this rule:

2 x (join timer) < leave timer < leaveAll timer

•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.

•Mode – Indicates VLAN membership egress mode for an interface. (Default: Access)

-Access – Sets the port to operate as an untagged interface. All frames are sent untagged.

-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 sent untagged.
