vsr> show state vrf <vrf> interface system-loopback <system-loopback> counters out-unicast-pkts

out-discards (state only)

The number of outbound packets that were chosen to be discarded even though no errors had been detected to prevent their being transmitted.

Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ‘last-clear’.

vsr> show state vrf <vrf> interface system-loopback <system-loopback> counters out-discards

out-errors (state only)

For packet-oriented interfaces, the number of outbound packets that could not be transmitted because of errors.
