SNMP agents run in network elements and respond to Network
Management Station (NMS) queries (GETs). SNMP provides a
means to query all terminals assigned to a specific community. Each
community should have a unique name, and all members of a
community have the same access privileges. You can assign a single
terminal to multiple communities.
Agents send unsolicited reports (traps) back to a specified IP address
when a particular network activity occurs. The following traps are
supported: cold start, warm start, authentication failure, link down,
and link up.
To add a new community:
1. Click the Agent tab.
2. In the Traps section, click Add Community.
3. Type the new community name, and then click OK.
