NETGEAR 8800 Chassis Switch CLI Manual • Ready (R)-The port is ready to accept a link. • Not Present (NP)-The port is configured, but the module is not installed in the slot. • Loopback (L)-The port is in Loopback mode. • Transmit Collisions (TX Coll)-The total number of collisions seen by the port, regardless of whether a device connected to the port participated in any of the collisions. • Transmit Late Collisions (TX Late Coll)-The total number of collisions that have occurred after the port's transmit window has expired. • Transmit Deferred Frames (TX Deferred)-The total number of frames that were transmitted by the port after the first transmission attempt was deferred by other network traffic. • Transmit Errored Frames (TX Errors)-The total number of frames that were not completely transmitted by the port because of network errors (such as late collisions or excessive collisions). • Transmit Lost Frames (TX Lost)-The total number of transmit frames that do not get completely transmitted because of buffer problems (FIFO underflow). • Transmit Parity Frames (TX Parity)-The bit summation has a parity mismatch. Port Monitoring Display Keys For information about the available port monitoring display keys, see the show ports statistics command. Example The following command displays transmit error statistics for slot 5, ports 4 through 7, on the switch with auto-refresh disabled: show ports 5:4-5:7 txerrors no-refresh The following is sample output from this command: Port Transmission errors Port Link Tx Tx Tx Tx Tx Tx State Coll Late coll Deferred Errors Lost Parity 5:4 R 0 0 0 0 0 0 5:5 R 0 0 0 0 0 0 5:6 R 0 0 0 0 0 0 5:7 R 0 0 0 0 0 0 Link State: A-Active, R-Ready, NP-Port not present, L-Loopback show rmon memory show rmon memory {detail | } 408 | Chapter 8.
