Configuring Remote Access
C-2 114084 Rev. A
If you are using EZ-Install over Frame Relay to boot an AN/ANH/ARN, you
can have up to 20 PVCs for a single Frame Relay interface on the upstream
router. If you have more than 20 PVCs on the interface where EZ-Install is
occurring, the EZ-Install process may fail. To ensure that the process does not
fail, configure no more than 20 PVCs for a Frame Relay interface.
If the AN/ANH/ARN will have small routing or forwarding tables, you can
increase performance by reducing local memory and allocating more global
memory for buffers. If the router will have large tables (for example, more
than 500 servers), you might want to increase the local memory allocation.
Notes
If you use TFTP to transfer the software image file to upgrade or restore the
router’s file system, be sure to specify the router’s image (an.exe for the
AN/ANH or arn.exe for the ARN).
Bay Networks supports BOOTP service on UNIX workstations, but not PCs.
If you want to use 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/ARN, you cannot use EZ-Install or Netboot directly from a
FDDI interface. On an AN/ANH, you cannot use EZ-Install or Netboot
directly from a Token Ring interface.
You need Version 8.10 or later to perform Directed Netboot.
If you have a LAN protocol analyzer available, you may want to use it to
troubleshoot BOOTP server communication errors. (Appendix A provides
guidelines for using Packet Capture and an analyzer to isolate these errors.)
Versions earlier than 7.80 do not include the Technician Interface Packet
Capture utility.
The 12-port ANH polls the internal repeater module for operation 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 base
board 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.
