Acceptable Frame Type — Allows you to set the switch port to accept all frame types, including VLAN tagged or VLAN untagged frames, or only tagged
l
frames.
Ingress Filtering — Discards incoming frames for VLANS that do not include the ingress port in their member set, if enabled.
l
GVRP Status — Enables/disables GVRP (GARP VLAN Registration Protocol) for the port. GVRP defines a way for switches to exchange VLAN information to
l
automatically register VLAN members on ports across the network. GVRP must be globally enabled for the switch before you can individually enable
GVRP for a specific port. For more information, see "GVRP."
GARP Join Timer — Specifies the interval (in centiseconds) between transmitting requests/queries to participate in a VLAN group. (The range is 20 to
l
1000 centiseconds.)
GARP Leave Timer — Specifies the interval (in centiseconds) a port waits before leaving a VLAN group. This time should be set to more than twice the
l
join time. This interval ensures that after a Leave or LeaveAll message has been issued, the applicants can rejoin before the port actually leaves the
group. (The range is 60 to 3000 centiseconds.)
GARP LeaveAll Timer — Specifies the interval (in centiseconds) between sending out a LeaveAll query message for VLAN group participants and the
l
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. (The range is 500 to 18000 centiseconds.)

Console(config-if)#switchport ingress-filtering
Console(config-if)#
Trunk Settings
On the Trunk Settings page, you can specify the default port VLAN ID (PVID) for ports that are configured as trunk members. When an untagged packet
enters the switch, it is, by default, tagged with the ID specified by the port's PVID.
For each trunk listed in the Trunk column, the following options are available:
PVID — Identifies the VLAN ID assigned to untagged frames that are received on each trunk port. To assign a VLAN ID as the port's PVID, the port must
l
be an untagged VLAN member.
Acceptable Frame Type — Sets the switch trunk ports to accept either both tagged and untagged frames or only tagged frames.
l
Ingress Filtering — Discards incoming frames for VLANs that do not include the trunk in their member set at the ingress ports, if enabled.
l
GVRP Status — Enables/disables GARP VLAN Registration Protocol (GVRP) for the trunk. GVRP defines a way for switches to exchange VLAN information
l
to automatically register VLAN members on ports across the network. GVRP must be globally enabled for the switch before you can individually enable
GVRP for a specific trunk. For more information, see "GVRP."
