Gathering Network Statistics

When you assign all ports on the 24-Port Module to the same network, an installed management module can simultaneously monitor all ports on one connector individually as it monitors the ports on the other connector collectively.

For example, you can use an installed EMM or Distributed Management Module (DMM) to simultaneously:

❑Monitor ports 1 through 12 individually

❑Sum up statistics for ports 13 through 24 at a single “logical port” (port 13)

Gathering statistics for individual ports on one connector enables network management to provide a detailed statistical view of each port on that connector. Collective statistics gathering for all ports on the other connector ensures you have at least a high-level statistical view of ports on that connector.

An ONline management command lets you switch to monitor the other connector. The following section describes the SET MODULE command.
