SPAN to File

SPAN to File feature is an extension of the pre-existing SPAN feature to allow network packets to be mirrored to a file instead of an interface, so that they can be analyzed later. The file format is PCAP, so that it can be easily used with tools such as tcpdump or wireshark.

Release 7.1.2

For more information about the feature, see the Configuring Traffic Mirroring chapter.

File Mirroring

File mirroring feature enables the router to copy files or directories automatically from /harddisk:/mirror location in active RP to /harddisk:/mirror location in standby RP or RSP without user intervention or EEM scripts.
