VSS Specific Examples
Example: Capturing and Storing in a file (Attachment Point in VSS Active
Switch)
This example shows how to do a simple capture and store operation when the attachment point is in VSS
active switch itself:
Step 1
Launch a capture session by entering the following commands in VSS active switch:
vss_dut1# monitor capture mycap interface gi 1/1/1 in
vss_dut1# monitor capture mycap match ipv4 any any
vss_dut1#
monitor capture mycap file location bootflash:mycap.pcap
vss_dut1# monitor capture mycap limit packets 10 duration 10
vss_dut1# monitor capture mycap start
