Ingress Filtering
– If ingress filtering is enabled, incoming frames
for VLANs which do not include this ingress port in their member set
will be discarded at the ingress port. (Default: Disabled)
- 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, it does 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 2-14.)
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
* – The interval between transmitting requests/
queries to participate in a VLAN group. (Range: 20-1000 centiseconds;
Default: 20)
•
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)
