Important Considerations
■
You must already have an analyzer port configured. First designate a
bridge port to serve as the analyzer port and connect the analyzer to
that port. See “analyzer add” earlier in this chapter for details. The
analyzer port and the monitor port must be on the same module.
■
The MAC address of the analyzer port is displayed when you configure
that port, and when you display the roving analysis configurations on
the module to which the analyzer is attached.
■
The media type of the analyzer port must match the media type of the
port being monitored. Fast Ethernet and Gigabit Ethernet are the
same media type. You can use a Fast Ethernet (10 Mbps) port to
monitor a Gigabit Ethernet (100 Mbps) port, but a warning message
will be printed. If the sustained traffic load is greater than 10 Mbps,
the analyzer on the slower port may not see all the frames on the
faster port.
■
Once a port is selected to serve as a monitor port, the RMON data that
it can record is limited to the RMON groups (statistics, history, alarm,
event, protocolDir, and probeConfig) that do not require hardware
sampling.
■
If you replace the module that the monitored port resides on with a
module of a different media type, the roving analysis port (RAP)
configuration for the monitored port is reset.
