Frequency Error

Occurs when a ring station detects a frequency error.

 

A new station inserting into the ring can cause

 

downstream stations to be ″off frequency″. This

 

condition seems to happen more on 16 Mbps than 4

 

Mbps rings. This statistic is found in the total number

 

of Frequency errors reported in the Soft Error Report

 

MAC frame.

Token Error

Token errors occur when a token is destroyed or

 

corrupted. This usually occurs when devices insert or

 

remove themselves from the ring. This statistic is

 

found in the total number of token errors reported in

 

the Soft Error Report MAC frame.

Soft Error Report

The Soft Error Report contains a compilation of all soft

 

errors detected by a ring station. At every two-second

 

interval, each ring station will transmit a Soft Error

 

Report MAC frame to the ring error monitor if the

 

counters are greater than zero. This enables the ring

 

error monitor to maintain accurate error statistics. A

 

soft error refers to an intermittent network error that

 

causes data to be retransmitted. If the number of soft

 

errors becomes excessive, network reliability and

 

performance can be seriously impacted.

Ring Poll Event

A Ring Poll event is triggered by the occurrence of an

 

Active Monitor Present MAC frame. It is initiated by

 

the active monitor to all ring stations to:

 

∙ Inform standby monitors of the active monitor′ s

 

presence

∙

∙

Indicate that the ring is functioning correctly

Initiate a neighbor notification (NAUN)

The Token-Ring Promiscuous Statistics Group: This group gathers current utilization statistics from non-MAC packets on a particular token-ring interface. The statistics like data packets, data octets, broadcast packets, multicast packets, packet size, etc., are collected promiscuously. In other words, the device driver for the token-ring adapter must be enabled to deliberately copy all non-MAC packets even though they are not addressed to it.

Here is a list of statistics available under this group and their respective descriptions:

Drop Event

The number of events in which non-MAC packets were

 

dropped by the probe due to unavailability of

 

resources on the probe itself. It doesn′t represent the

 

number of packets dropped but the number of times

 

this condition was detected. If the drop events counter

 

constantly increments, it is an indication that there is

 

more activity on the segment than can be captured by

 

the network probe. You may want to consider

 

increasing the resources on your network probe. For

 

instance, if you are running the RMON application on

 

a workstation, you may want to allocate more real

 

memory and disk space to the RMON application. If

 

you are running an RMON subset on a bridge, router,
