Description Problems with capture instances connected to alarms

Symptom If an alarm is conﬁgured to start a packet capture instance, the instance

will appear to be started when the alarm triggers, but no packets will be

captured. If you are viewing the instance in Protocol Analyzer when the

alarm triggers, you could see a message indicating that the “instance no

longer exists”. Despite this error message, the instance is still there and

you can re-attach to it; however, no packets are captured.

If an alarm is conﬁgured to stop a packet capture, the packet capture is

restarted when the alarm is created or modiﬁed (deleting any packets

that were capture prior to setting the alarm). However, when the alarm

triggers, the packet capture is stopped correctly. [Defect IDs 0804–

009324]

Work-Around None.

Description Launching Protocol Analyzer from Internetwork Monitor results

Details Refer to the description on page 19.

Description Some Protocol Analyzer ﬁlter expressions are not converted

properly to RMON ﬁlter entries

Details In some cases, a Protocol Analyzer ﬁlter expression will not be converted

properly to RMON ﬁlter entries. This problem affects capture on all

agents, but does not affect local mode. No error is issued; however, the

packets captured are not correct for the expression speciﬁed.

In particular, if the ﬁlter expression includes at least two items (source

host, protocol, destination host, etc.) in addition to a packet status item,

the packet status portion of the ﬁlter is not converted.

Filtering on protocol LLC with a token ring agent also results in an

incorrect ﬁlter.

Work-Around Specify a ﬁlter expression that converts correctly, then post ﬁlter the cap-

tured data to further ﬁlter the captured packets. For example, if you

want to capture packets according to this ﬁlter expression:

(proto udp nfs) and (host ip kermit) and (status crc)
