Description
Display packet headers or packets that are received and sent from the packet forwarding engine for monitoring and verifying the functionality of on-box packet sniffing capabilities.
Options
| absolute-sequence |
Display absolute TCP sequence numbers. |
| brief | detail | extensive |
Display the specified level of output. |
| byte-offset |
Display the specified level of output. |
| count count |
Specify the number of packet headers to display (0 through 1,000,000). |
| egress |
Egress data traffic monitoring. |
| egress-interface |
Specify the egress interface where loopback is enabled. |
| ingress |
Ingress data traffic monitoring. |
| inner-dmac | inner-dst-ipv4 | inner-smac | inner-src-ipv4 |
Display the inner header addresses to monitor traffic and packet headers. |
| layer2-headers |
Display the link-level header on each line. |
| no-domain-names |
Suppress the display of the domain portion of hostnames. |
| no-promiscuous |
Do not put the interface into promiscuous mode. |
| no-resolve |
Do not attempt to convert host addresses to names. |
| no-timestamp |
Suppress timestamps on displayed packets. |
| outer-dmac | outer-dst-ipv4 | outer-smac | outer-src-ipv4 |
Display the outer header addresses to monitor traffic and packet headers. |
| print-ascii |
Display each packet in ASCII format. |
| print-hex |
Display each packet in hexadecimal format. |
| resolve-timeout timeout |
Amount of time the router or switch waits for each reverse lookup before timing out. You can set the timeout for 1 through 4,294,967,295 seconds. |
| size size |
Snap length of the frame to be captured, in bytes. |
| vlan-id |
VLAN identifier to monitor traffic. |
| vnid |
VXLAN identifier to monitor traffic. |
| write-file filename |
Write packets to the file specified. |
