Configuring Remote Access for AN and Passport ARN Routers
B-20 308614-14.20 Rev 00
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.
