RMON in Your System

3Com Transcend
RMON Agents
Your system supports RMON as follows:
RMON-1 support — The system software offers full-time embedded
RMON support using SNMP for seven RMON-1 groups. (RMON-1
defines 10 groups.)
RMON-2 Support — The system software offers embedded RMON
support for seven RMON-2 groups. (RMON-2 defines ten groups.)
RMON-2 enables the system RMON feature to see above the MAC
layer and monitor traffic based on network-layer protocols and
addresses.
The embedded RMON support software cannot receive RMONv2 updates
for IP, IPX, and AppleTalk unless you have identified and configured a
Virtual LAN (VLAN) protocol type.
RMON requires one probe per LAN segment. Because a segment is a
portion of the LAN that is 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 system. With this probe you
deploy RMON widely around the network at a cost of no more than the
cost of traditional network monitors.
Placing probe functionality inside the system has these advantages:
You can integrate RMON with normal device management.
The system can manage conditions proactively.
The system associates statistics with individual ports and then takes
action based on these statistics. For example, the system can generate a
log event and send an RMON trap if errors on a port exceed a threshold
set by the user.
