SNMP
Use the Administration > Management > SNMP page to set up Simple Network
Management Protocol (SNMP) for the ATA.
SNMP is a network protocol that allows network administrators to manage,
monitor, and receive notifications of critical events as they occur on the network.
The ATA supports SNMPv2 and SNMPv3. It acts as an SNMP agent that replies to
SNMP commands from SNMP Network Management Systems. It supports the
standard SNMP get, next, and set commands. It also generates SNMP traps to
notify the SNMP manager when configured alarm conditions occur. Examples
include reboots, power cycles, and INTERNET (WAN) events.
Enter the settings as described below. After making changes, click Submit to save
your settings, or click Cancel to redisplay the page with the saved settings.
