Important
Considerations
■
To manage RMON, you must assign an IP address to the system
through the EME management module. See the
Switch 4007
Enterprise Management Engine User Guide for information about
how to do this.
■
The system will always keep RMON statistics (group 1) data on all
ports.
■
The system will keep RMON history (group 2), alarm (group 3), and
event (group 9) data on as many ports as its resources allow.
■
Multilayer Switching Modules support additional RMON-1 and
RMON-2 groups.
■
The system will keep as much protocolDir (group 11), protocolDist
(group 12), and probeConfig (group 19) data as its resources will
allow.
■
All other RMON group data is hardware sampled. The system can
be configured to keep hardware-sampled RMON group data on up
to four ports per module.
■
RMON data for Gigabit Ethernet is supported on Layer 2 modules.
■
RMON data is not supported on Multilayer Gigabit Ethernet modules
except for the 4-port Gigabit Ethernet Switching module (3CB9RG4).
This module supports the statistics, history, alarm, and event groups.
■
There is no limit to the number of network management stations
monitoring the data.
