The VH-2402-L3 supports 6 Port Trunking groups, which may include from 2 to 8 switch ports each, except for a Gigabit Port Trunking group which consists of the 2 (optional) Gigabit Ethernet ports of the front panel. These ports are the two 1000BASE-SX, -TX or GBIC ports contained in a front-panel mounted module.

IEEE 802.1Q VLANs

IEEE 802.1Q (tagged) VLANs are implemented on the VH-2402-L3. 802.1Q VLANs allow tagging, which enables them to span the entire network (assuming all switches on the network are IEEE 802.1Q-compliant). IEEE 802.1Q VLANs also allow for dynamic VLAN registration using GVRP.

VLANs allow a network to be segmented in order to reduce the size of broadcast domains. All packets entering a VLAN will only be forwarded to the stations (over IEEE 802.1Q enabled switches) that are members of that VLAN, and this includes broadcast, multicast and unicast packets from unknown sources.

VLANs can also provide a level of security to your network. IEEE 802.1Q VLANs will only deliver packets between stations that are members of the VLAN.

Broadcast Storm Control

Broadcast storms consist of broadcast packets that flood and/or are looped on a network causing noticeable performance degradation and in extreme cases, network failure. Broadcast storms can be caused by malfunctioning NICs, bad cable connections and applications or protocols that generate broadcast traffic, among others.

Broadcast storms have long been a concern for network administrators with routers traditionally being
