CONFIGURING THE SWITCH

-Ingress filtering only affects tagged frames.

-If ingress filtering is disabled and a port receives frames tagged for VLANs for which it is not a member, these frames will be flooded to all other ports (except for those VLANs explicitly forbidden on this port).

-If ingress filtering is enabled and a port receives frames tagged for VLANs for which it is not a member, these frames will be discarded.

-Ingress filtering does not affect VLAN independent BPDU frames, such as GVRP or STP. However, they do affect VLAN dependent BPDU frames, such as GMRP.

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 3-15.)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 Timer10 – The interval between transmitting requests/ queries to participate in a VLAN group.

(Range: 20-1000 centiseconds; Default: 20)

GARP Leave Timer10 – 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 Timer10 – 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)

10.Timer settings must follow this rule: 2 x (join timer) < leave timer < leaveAll timer
