• The IP encapsulationtype. All systems that have Ethe rnet
interfaces are IEEE 802.3 compliant, but very few actually
do 802.3 (LLC/SNAP)packet encapsulation. Use the
default,Ethernet, unless you know absolutely that your LAN
does 802.2/802.3 (LLC/SNAP)packet encapsulation.
Youcan use the defaults for the name of the image file containing the
RemoteAccess Concentrator’s software and the address of the preferred
loadserver host. If the value for the im agen ame is incorrect, the Remote
Access Concentrator cannot boot.Correct the name using the image
command. If the address forthe preferred load server host is incorrect,
the boot takes longer,since the Remote Access Concentrator has to
broadcast for a host. Correct the load host’s address using the addr
command.
Confirm that the Remote Access Concentrator’sboot parameters are
correct by using thea ppropriateROM Monitor commands. M odifyany
boot parameters that are incorrect or missing. Boot the Remote Access
Concentrator eitherby entering the bootc ommand at theservice port
terminal, or by resetting the module.
Load Server Host Not RespondingThe Remote Access Concentrator can boot from one ofthe following
hosts acting as a load server host:
• AUNIXhostontheLANusingBFSviaerpcd.
• Another Remote AccessConcentrator using BFS.
• Any host (UNIX or non-UNIX) using tftp.
• A WindowsNT host usingBFS via erpcd.
Thefollowing subsections discuss troubleshootingf or someof these load
server hosts.
