Nortel Networks 14.2 manual Implementation Notes

Configuring Remote Access for AN and Passport ARN Routers

Implementation Notes

This section contains notes for operating an AN/ANH or ARN router at a remote site.

•If you use TFTP to upgrade or restore the router’s file system, be sure to specify the software image file (an.exe for the AN/ANH or arn.exe for the ARN).

•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 Manager workstation, transfer the files you want to netboot from the PC to a UNIX workstation and configure the workstation as a BootP server.

•On an AN/ANH or ARN router, you cannot use EZ-Install or Netboot directly from a FDDI interface. On an AN/ANH router, you cannot use EZ-Install or Netboot 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 to troubleshoot BootP server communication errors. (For information about using the Packet Capture utility or an analyzer to isolate these errors, see “Guidelines for Using Packet Capture” and “Guidelines for Using a LAN Protocol 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; it does not poll individual Ethernet repeater ports for connection (link) status. Therefore, the 12-port ANH is aware of the connection between the baseboard and repeater module, but is not aware of any connection between the repeater module and the Ethernet network. If the repeater module interface state reports an operational status, the 12-port ANH may continue to transmit information through the repeater module even though a physical Ethernet connection does not exist.

•At the AN Monitor prompt, you cannot view the contents of the local file system on the flash memory card. Be sure to remember the name of the configuration file when performing a Directed Netboot from the AN Monitor prompt.

•You can issue a boot command from the AN Monitor prompt. Specify a local boot by entering 1: for the volume name.
