Network Monitoring
Feature Function Benefit
RMON support
Support for Token-
Ring specific remote
monitoring. Enables collection and analysis
of enhanced traffic-
management data.
Passive Port
Monitoring All traffic flowing on
the monitored port is
copied to the
monitoring port (the
monitoring port is a
true copy of the
monitored port). Eases the management task by
making it easy to collect
Token-Ring statistics with a
special passive network
analyzer.
Active Port
Monitoring
All traffic switched
to and from the
monitored port is
also sent to the
monitoring port (the
order and timing of
frames on the
monitoring port can
be different). Eases the management task by
making it easy to collect
network statistics and carry out
protocol analysis. Active
monitoring respects the MAC
protocol, allowing the use of a
standard network analyzer.
Built-in port
counters
Many MAC layer,
error, and frame
forwarding counters
are collected per port Provides a detailed picture of
port traffic.
Port Mirroring Allows any port to be
used for connecting a
network analyzer.
Can then duplicate
traffic n any other
port to troubleshoot
attached segments. Greatly simplifies system
management and facilitates
collection of network statistics.
