With the Dual Trunk E1 Router you can monitor the entire WAN protocol stack. Higher level
protocols can be monitored using RMON-2. PPP connections can be monitored using RMON-1, and
the physical layer can be monitored using diagnostic capabilities as outlined in RFC 1406.
Monitoring Higher Protocol Layers
The Dual Trunk E1 Router includes RMON-2 capabilities. This lets you identify the Top Talkers
(256 greatest bandwidth users), and drill down to the Top Applications to see which applications are
using the most bandwidth. It also lets you track and report traffic sent between pairs of network
addresses and categorizes them by applications and protocols.
Table 1-2 lists the RMON tables supported in RMON-2.
Using the optional ChoiceView Plus software application, you can display the statistics gathered by
RMON-2.
To take advantage of the Dual Trunk E1 Router’s RMON-2 capabilities, Black Box has created an
application, ChoiceView Plus, that allows you to display RMON-2 data in real-time, graphical, and
tabular formats.
