capture

This command invokes the packet capture ability of the Uplogix Local Manager. The secondary Ethernet port can be configured to monitor a SPAN port of a switch and capture packets matching a variety of conditional statements. Only the packets destined for the secondary Ethernet port meeting the regular expressions defined in the conditional statements are captured.

A single capture is available to view in text mode or it can be transferred to another system in text or pcap form.

The capture will spool up to 5 meg of capture detail.
