Configures onboard packet capture on the interface.
Exec mode
This command is available only to users with the admin role.
Only one mirror session is allowed per port.
You must configure the interface before configuring packet capture.
A maximum of 10 mirror sessions per device are allowed.
Packet capture is not allowed if maximum PCAP files are already created.
When packet-count parameter is specified, the packet capture automatically stops on the interface after the specified number of packets are captured.
The maximum number of existing PCAP files cannot exceed 25.
After packet capture is configured on the required ports, use the capture start command to
start capturing packets in the active running PCAP file.
The capture stop command stops writing the packet to PCAP file and
moves the active file to next available inactive PCAP file.
The start and stop options do not clear hardware entries.
Onboard packet capture is not persistent across reboot.
The following example configures both ingress and egress packet capture, up to 100, on ethernet interface 1/1.
device# capture packet interface ethernet 1/1 direction both packet-count 100
The following example removes packet capture configuration on the specified ethernet slot/port.
device# no capture packet interface ethernet 1/1
The following example starts, verifies, and stops packet capture.
device# capture start device# show capture packet config capture start device# capture stop
