- 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 Timer
queries to participate in a VLAN group.
(Range: 20-1000 centiseconds; Default: 20)
• GARP Leave Timer
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
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)
