Which command captures network packets on the Ethernet interface on TX series endpoint from the CLI?

'utils network capture' is the Cisco TX series endpoint CLI command that initiates a packet capture on the Ethernet interface, providing packet-level network visibility within the Cisco-managed CLI framework rather than exposing the underlying OS directly.

'network mtr' is a network path diagnostic tool combining ping and traceroute functionality and does not perform packet capture.

'utils ntp config' is used to configure NTP server settings and has no relationship to packet capture functionality.

'tcpdump' is a raw Linux utility not directly accessible from the Cisco TX series endpoint CLI; the correct abstracted CLI equivalent is 'utils network capture'.
