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

Network Management Protocol

For a description of all MIBs (Management Information Bases) and MIB objects

supported by the router, see

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

filenames beginning with "at".

To Avoid Problems

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/.

Store a backup of the latest configuration script in case the configuration file on

the router is accidentally deleted or damaged.

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.
