Table 6-14: show mac Command Output Fields Field Description MAC Module and port. Rcv-Frms Frames received on the port. Xmit-Frms Frames transmitted on the port. Rcv-Multi Multicast frames received on the port. Xmit-Multi Multicast frames transmitted on the port. Rcv-Broad Broadcast frames received on the port. Xmit-Broad Broadcast frames transmitted on the port. Dely-Exced Total transmit frames aborted due to excessive deferral. MTU-Exced Frames for which the MTU size was exceeded. In-Discard Incoming frames that were discarded because the frame did not need to be switched. Lrn-Discard CAM entries discarded due to page full in EARL. In-Lost Incoming frames that were lost before being forwarded (due to insufficient buffer space). On-Lost Outgoing frames that were lost before being forwarded (due to insufficient buffer space). SMT-Address SMT address of the FDDI port. Curr-Path Current path used (primary or secondary). TReq T-req (token rotation time request) value. TNeg T-neg (negotiated token rotation time) value. TMax T-max (maximum token rotation time) value. TVX Value of the valid transmission timer. Upstream-Nbr MAC address of the current upstream neighbor. Downstream-Nbr MAC address of the current downstream neighbor. Old-Upstrm-Nbr MAC address of the previous upstream neighbor. Old-Downstrm-Nbr MAC address of the previous downstream neighbor. Rcv-Smt Number of SMT frames received by the port. Xmit-Smt Number of NSMT frames transmitted by the port. Rcv-llc Number of NLLC frames received by the port. Xmit-llc Number of LLC frames transmitted by the port. Rcv-Octet Number of octet frames received on the port. Xmit-Octet Number of octet frames transmitted on the port. Rcv-Unicast Number of unicast frames received on the port. Rcv-Multicast Number of multicast frames received on the port. Rcv-Broadcast Number of broadcast frames received on the port. Xmit-Unicast Number of unicast frames transmitted on the port. Xmit-Multicast Number of multicast frames transmitted on the port. Xmit-Broadcast Number of broadcast frames transmitted on the port. Tvx-Exp-Ct Number of times the TVX timer expired. RingOp-Ct Number of times the ring became operational. Last-Time-Cleared Date and time of the last clear counters command.
