RMON

Using the Remote Monitoring (RMON) capabilities of the switch allows network administrators to
improve system efficiency and reduce the load on the network. The following sections explain more
about the RMON concept and the RMON features supported by the switch.

NOTE

You can only use the RMON features of the system if you have an RMON management application,
and have enabled RMON on the switch.

About RMON

RMON is the common abbreviation for the Remote Monitoring Management Information Base (MIB)
system defined by the Internet Engineering Task Force (IETF) documents RFC 1271 and RFC 1757,
which allows you to monitor LANs remotely.

config syslog delete <host name/ip> <facility>
{<priority>

local use (local0 - local7).

priority

messages with the selected priority or
higher (more critical). Priorities include

notice, info, and debug. If not specified, only
critical priority messages and are sent to the
syslog host.
