Configuring the Switch
* Timer settings must follow this rule: 2 x (join timer) < leave timer < leaveAll timer

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.
However, they do affect VLAN dependent BPDU frames, such as GMRP.
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, 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 section on page 30.) 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)
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)
Mode – Indicates VLAN membership mode for an interface. (Default: 1Q Trunk)
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. Note that frames belonging to the port's default VLAN
(i.e., associated with the PVID) are also transmitted as tagged frames.
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.
