Bridging

The XP-2000 provides the following types of high-speed bridging:

Address-based bridging – The XP-2000 performs this type of bridging by looking up the destination address in an L2 lookup table on the expansion module that receives the bridge packet from the network. The L2 lookup table indicates the exit port(s) for the bridged packet. If the packet is addressed to the XP-2000’s own MAC address, the packet is routed rather than bridged.

Flow-based bridging – The XP-2000 performs this type of bridging by looking up an entry in the L2 lookup table containing both the source and destination addresses of the bridge packet.

Your choice of bridging method does not affect XP-2000 performance. However, address-based bridging is more efficient because it requires fewer table entries while flow-based bridging provides tighter management and control over bridged traffic.

The XP-2000 ports perform address-based bridging by default, but can be configured to perform flow-based bridging instead of address-based bridging on a per-port basis. A port cannot be configured to perform both types of bridging at the same time.

Port and Protocol VLANs

The XP-2000 supports the following types of Virtual LANs (VLANs):

Port-based VLANs – A port-based VLAN is a set of ports that comprises a Layer-2 broadcast domain. The XP-2000 confines MAC-layer broadcasts to the ports in the VLAN on which the broadcast originates. XP-2000 ports outside the VLAN do not receive the broadcast.

Protocol-based VLANs – A protocol-based VLAN is a named set of ports that comprises an IP or IPX broadcast domain. The XP-2000 confines IP or IPX broadcasts to the ports within the IP or IPX based VLAN. Protocol-based VLANs sometimes are called subnet VLANs or Layer- 3 VLANs.

You can include the same port in more than one VLAN, even in both port-based and protocol-based VLANs. Moreover, you can define VLANs that span across multiple

XP-2000s. To simplify VLAN administration, the XP-2000 supports 802.1q trunk ports, which allow you to use a single port to “trunk” traffic from multiple VLANs to another XP-2000 or switch which supports 802.1q.

Routing

The XP-2000 provides high-speed routing for the following protocols:
