x Ingress Filtering examines the tagged header of each tagged frame that enters a port and determines whether the tagged frame and the port that received the frame are members of the same VLAN. If they belong to the same VLAN, the port accepts the frame. If they belong to different VLANs, the port discards the frame. If Ingress filtering is disabled, any tagged frame is accepted on any port on the switch. It does not matter whether the frame and port belong to the same or different VLANs.

x HOLB Prevention - Head Of Line Blocking occurs when many ports send frames to the same output port. This puts the frames in contention for output port and all frames must wait behind, thus the head of the line goes first. The shared memory switching fabric architecture eliminates any possibility of
x When QoS is enabled, you can map the Type of Service of your choice (according to IEEE 802.1p) to the 4 priority levels provided.
x There are 3 different modes of VLANs supported in this switch, 802.1Q,
x GVRP Enable State is used with IEEE 802.1Q VLANs. GVRP enables the switch to dynamically create 802.1Q compliant VLAN links with other switches running GVRP. This reduces the chance for errors in VLAN configuration by automatically providing VLAN ID (VID) consistency across the network. You can use GVRP to propagate VLANs to other GVRP switches instead of manually having to set up VLANs in each switch. In order to activate GVRP without overlapping VLANs, follow these steps:
1.Assign static VLANs.
2.Take out ports that belong to assigned VLANs from Default VLAN.
3.Assign those ports to Local VID in Switch Port Configuration Menu.
4.Tag the uplink port in the Untagged Configuration Menu.
5.Turn on STP in Switch Configuration Menu.
