Connecting BayStack AN and ANH Systems to a Network
A-8
Viewing an AN/ANH error message and entering commands through a modem
connection may simplify troubleshooting if you are not at the AN/ANH site. As an
alternative, you can ask the person at the AN/ANH site to read the console
messages to you and then you can enter the commands you want.
Displaying Statistics and Error Messages
Use the Statistics Manager Quick Get tool or the Technician Interface get
command to display the number of BOOTP and TFTP packets forwarded and
dropped for each interface in the path between the AN/ANH and the BOOTP
server. Use the Events Manager tool or the Technician Interface
log command to
display the events associated with the interface and the BOOTP and TFTP
protocols.
Refer to Managing Routers for instructions on using the Statistics Manager’s
Quick Get tool and the Events Manager. That guide also describes each event
displayed in the log.
Refer to Using Technician Interface Software for instructions on using the
get and
log commands.
Guidelines for Using Packet Capture
Use the Packet Capture utility to view incoming or outgoing BOOTP or TFTP
packets and isolate errors to a specific router interface. This utility is available
through the Technician Interface on routers running Version 7.80 or higher.
Refer to Using Technician Interface Software for instructions on how to use
Packet Capture. Refer to Configuring SNMP, BOOTP, DHCP, and RARP
Services for a description of BOOTP packets.
Use Packet Capture as follows:
1. Test the BOOTP server’s next-hop router in the path to the AN/ANH.
2. Test the upstream router’s interface to the AN/ANH.
3. Test the upstream router’s interface to the next-hop router.
Note: The instructions that follow assume that Version 7.80 or higher is
running on all routers in the path between the AN/ANH and the BOOTP
server.
