Pressing Ctrl-E toggles you through the event log, debug log, hardware information, and configuration information screens.
A Address and Device Mapping Devices attached to the router are discovered during power on. The router defaults to AUTO mapping mode, which automatically maps the SCSI devices at each power on. The router maps devices sequentially as it scans the channels and discovers the devices (devices are discovered by channel, lowest SCSI ID and LUN first). Devices are mapped to FC LUNs, starting from LUN 0 to LUN 63 (64 LUNs are supported, including an optional router LUN).

Address and Device Mapping Loop ID to AL_PA Mapping During the Fibre Channel Arbitrated Loop (FC-AL) initialization process, a unique Arbitrated Loop Physical Address (AL_PA) value is assigned to each port on the loop. Not all of the 256 hex values are allowed as AL_PA values per FC-AL, so Loop IDs are used to represent the 125 addresses that the router can use. You can assign a Loop ID to the router. See Changing the Router’s Loop ID on page 3-8. Table A-2 shows how a Loop ID value maps to an AL_PA.
VFS113 Rack/Desktop Model User’s Guide Table A-2.
D LAN Configuration Before you can access the Router Administrator software using the Ethernet port, you must set up your router for TCP/IP. The following sections describe the router’s TCP/IP setup. A router that is part of a TCP/IP network requires three basic IP configuration elements: IP address, subnet mask, and default gateway IP address. The router’s IP address must be unique to the network in which the router resides.
VFS113 Rack/Desktop Model User’s Guide Using Address Resolution Protocol The ARP configuration method requires no IP address re-configuration of any computer on the network. The ARP command is available in various forms and sometimes with varying syntax in UNIX and Windows systems. All routers are shipped with a unique Media Access Control (MAC) hardware address (sometimes referred to as a physical address).
LAN Configuration Dynamic Host Configuration Protocol Configuration The Dynamic Host Configuration Protocol (DHCP) is a protocol designed to make IP address assignment dynamic and automatic. When a router is configured in DHCP mode, it generates a request for an IP address. The address is provided to the router and can be used from that point forward. In the dynamic address assignment mode, an IP address is leased to a DHCP-configured router.
VFS113 Rack/Desktop Model User’s Guide 3 Select Ethernet Config and press Enter. The Network Management System Console screen displays. From here you can access the LAN settings.
