Feature Description

Arbitrated-loop support The MP Router supports only one arbitrated-loop physical address (AL_PA)

device per port. However, you can use MP Routers in fabrics where multiple

loop devices are directly attached to Fabric OS-based switches, such as the

HP StorageWorks SAN Switch 2/32.

Gigabit Ethernet (GigE)

support

XPath OS supports GigE port connections, which in turn support the optional

multi-protocol routing services. Each Gigabit Ethernet port has its own IP

address and supports address resolution protocol and ping. Ports must be

specifically configured as GigE ports. When configured as GigE, ports are

equivalent to 1000Base-SX or 1000Base LX.

Exchange-based trunking The XPath OS exchange-based trunking feature optimizes load sharing across

interswitch links (ISLs). It increases overall bandwidth by grouping all ISLs

between the same pair of switches and load-sharing traffic across all equal

path links. This functionality works between two MP Routers, as well as from

an MP Router to any other Fabric OS-based switch. For more information, see

Chapter 8, “Using ISL trunking.”

Management access ports The MP Router provides two 10/100 Mbit/sec Ethernet ports, which are

capable of being configured as a single IP address or as two unique IP

addresses, and an RS-232 port. If you configure the Ethernet ports with

unique IP addresses, when the router is joined to a fabric, the router must

have a virtual Ethernet IP identity for routing. You can handle this by setting a

virtual management IP address for the router. See the HP StorageWorks XPath

OS 7.4.x command reference guide for more information.

Multiple user accounts XPath OS allows you to create multiple user accounts and assign

administrative or user roles.

Name Server support The MP Router includes an FC-GS3-compliant Name Server implementation.

The Name Server supports all commands specified as “Required” in the

FC-MI Fibre Channel specification.
