Usage Guidelines
•
The maximum number of monitoring sessions is limited to one per chassis and/or stack.
•
You cannot configure port mirroring and monitoring on the same switching ASIC on OmniSwitch
6850 Series and OmniSwitch 6855 Series switches. Each switching ASIC controls 24 ports (e.g., ports
1–24, 25–48, etc.). For example, if a port mirroring session is configured for ports 1/12 and 1/22, then
configuring a port monitoring session for any of the ports between 1 and 24 is not allowed.
•
If a port mirroring session is configured across two switching ASICs, then configuring a monitoring
session is not allowed on any of the ports controlled by each of the ASICs involved. For example, if a
port mirroring session is configured for ports 1/8 and 1/30 on a 48-port switch, then configuring a port
monitoring session involving any of the ports between 1 and 48 is not allowed.
•
By default, a file called pmonitor.enc is created in the /flash directory when you configure and enable
a port monitoring session. Use the file option to create a user-specified file.
•
By default, more-recent frames will overwrite older frames in a port monitoring file if the total data
exceeds the specified file size. Use the overwrite off option to prevent this from occurring.
•
Only the first 64 bytes of the traffic will be captured.
•
The format of the file created is compliant with the ENC file format (Network General Sniffer Network
Analyzer Format).
