3Com Transcend RMON Agents

RMON requires one probe per LAN segment. Because a segment is a portion of the LAN separated by a bridge or router, the cost of implementing many probes in a large network can be high.

To solve this problem, 3Com has built an inexpensive RMON probe into the Transcend SmartAgent software in each CoreBuilder 6000 system. This probe allows you to deploy RMON widely around the network at a cost of no more than that for traditional network monitors.

Placing probe functionality inside the CoreBuilder 6000 system has these advantages:

■You can integrate RMON with normal device management.

■The CoreBuilder system can manage conditions proactively.
