Correcting Remote Access ConcentratorParameters

Thefollowing parametersmust accuratelyreflect boththe RemoteAccess

Concentrator and thenetwork environment in which it operates.

Verify the Remote Access Concentrator’sIP address using the addr

command. If your network configuration does not support the factory

defaults, verifythe following parameters using the addr command:

• The broadcast address.

• The subnet mask.

• The load/dump gateway address (which mu st be specified if

the preferredload server host is located on another network

or subnet).

Error Description

ARPe rrors AddressResolution Protocol (ARP) errors indicate that

theRemote Access Concentrator is configured to boot

froma specified host, but the host would not transmit its

Ethernetaddress to the Remote Access Concentrator.

Possibly,the Remote Access Concentrator configuration

includesthe wrong IP encapsulation, or the subnet mask

ismisconfigured on the host or the Remote Access

Concentrator.

ERPC layer

errors See Table 4 -3.

Abortsrx’d The host’s BFS transmitted an abort in response to the

RemoteAccess Concentrator’sOpen Request. This often

meansthat the requested file does not exist on that

server,or that it is installed in the wrong directory or

with the wrong permiss ions. Run erpcd –D on the host

toobtain more information.
