SNMP and MIBs
You can remotely monitor many features of the router using Simple Network
Management Protocol (SNMP). The router supports SNMP Version 1
(SNMPv1), SNMP Version 2c (SNMPv2c) and Version 3 (SNMPv3). For
information about SNMP and configuring SNMP, see
Chapter 54, Simple
Network Management Protocol (SNMP) .
For a description of all MIBs (Management Information Bases) and MIB objects
supported by the router, see
Appendix C, SNMP MIBs .
The router’s Documentation and Tools CD-ROM contains the MIB files that are
supported by the router, including the Allied Telesis enterprise MIB. The
Allied Telesis enterprise MIB files includes
atrouter.mib,
and other files with
filenames beginning with “at”.
To Avoid Problems
Backup software
files
Store a backup of the current router software. If the router software is
accidentally cleared from the router’s flash memory, you must reload the
software files. If your access to the Internet is via the router, then you need the
files on your LAN. You may want to keep a copy of the current files on a TFTP
server on your network. You can download router software from
www.alliedtelesis.com/support/ .
Backup
configuration script
Store a backup of the latest configuration script in case the configuration file on
the router is accidentally deleted or damaged.
Backup router
If your network has many routers, you may want to keep a backup router
ready in case one malfunctions. When you upgrade software on routers in the
network, upgrade the backup too. Store one current config script on the backup
for each router in your network, so that if a problem occurs you need only set
the configuration file with which it boots to match the router it replaces.
