Configuring Remote Access for AN and Passport ARN RoutersB-20 308614-14.20 Rev 00Implementation NotesThis section contains notes for operating an AN/ANH or ARN router at a remotesite.• If you use TFTP to upgrade or restore the router’s file system, be sure tospecify the software image file (an.exe for the AN/ANH or arn.exe for theARN).• Nortel Networks supports BootP service on UNIX workstations, but not PCs.If you want to netboot and you are using a PC as your Site Managerworkstation, transfer the files you want to netboot from the PC to a UNIXworkstation and configure the workstation as a BootP server.• On an AN/ANH or ARN router, you cannot use EZ-Install or Netboot directlyfrom a FDDI interface. On an AN/ANH router, you cannot use EZ-Install orNetboot directly from a token ring interface.• You need BayRS Version 8.10 or later to use Directed Netboot.• If you have a LAN protocol analyzer available, you may want to use it totroubleshoot BootP server communication errors. (For information aboutusing the Packet Capture utility or an analyzer to isolate these errors, see“Guidelines for Using Packet Capture” and “Guidelines for Using a LANProtocol Analyzer” on page B-9.)• BayRS Versions earlier than 7.80 do not include the Packet Capture utility.• The 12-port ANH polls the internal repeater module for operational status; itdoes not poll individual Ethernet repeater ports for connection (link) status.Therefore, the 12-port ANH is aware of the connection between the baseboardand repeater module, but is not aware of any connection between the repeatermodule and the Ethernet network. If the repeater module interface statereports an operational status, the 12-port ANH may continue to transmitinformation through the repeater module even though a physical Ethernetconnection does not exist.• At the AN Monitor prompt, you cannot view the contents of the local filesystem on the flash memory card. Be sure to remember the name of theconfiguration file when performing a Directed Netboot from the AN Monitorprompt.• You can issue a boot command from the AN Monitor prompt. Specify a localboot by entering 1: for the volume name.
