Connecting BayStack AN and ANH Systems to a Network

C-2

• If you are using EZ-Install over Frame Relay to boot an AN/ANH, 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 will have small routing or forwarding tables, you can increase

performance by reducing local memory and allocating more global memory

for buffers. If the AN/ANH 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 AN/ANH image (an.exe).

• 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.

• You cannot use EZ-Install or Netboot directly from a Token Ring or FDDI

interface.

• You need Version 8.10 or higher 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 prior to 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.

• You can issue a

boot command from the Diagnostic Monitor prompt and

specify a local boot by using

1: as the volume name.
