Black Box LRU4240 Monitoring the Entire WAN Protocol Stack, Monitoring Higher Protocol Layers

Dual Trunk E1 Router

MONITORING THE ENTIRE WAN PROTOCOL STACK

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 1-2lists the RMON tables supported in 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.
