VLAN Configuration
•Ingress Filtering – Determines how to process frames tagged for VLANs for which the ingress port is not a member. (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 STP. However, they do affect VLAN dependent BPDU frames, such as GMRP.
•GARP Join Timer* – The interval between transmitting requests/queries to participate in a VLAN group. (Range:
•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:
•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:
•Mode – Indicates VLAN membership mode for an interface. (Default: 1Q Trunk)
-1Q Trunk – Specifies a port as an
-Hybrid – Specifies a hybrid VLAN interface. The port may transmit tagged or untagged frames.
•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
