Command introduced before JUNOS Release 7.4.

Description

Display status information about serial interfaces, including RS-232, RS-422/449, EIA-530, X.21, and V.35. You can include wildcard characters in the interface name to display more than one serial interface. See Interface Types.

Options

interface-type—On M-series and T-series routing platforms, the interface type is se-fpc/pic/port. On the J-series routing platform, the interface type is se-pim/0/port.

brief | detail | extensive | terse—(Optional) Display the specified level of output.

descriptions—(Optional) Display interface description strings.

Output bytes—Number of bytes transmitted on the interface.

Input packets—Number of packets received on the interface.

Output packets—Number of packets transmitted on the interface.

detail extensive

Input Errors

Input errors on the interface. The following paragraphs explain the counters whose meaning might not be obvious:

Errors—Sum of the incoming frame aborts and FCS errors.

Drops—Number of packets dropped by the input queue of the I/O Manager ASIC. If the interface is saturated, this number increments once for every packet that is dropped by the ASIC's RED mechanism.

Framing errors—Number of packets received with an invalid frame checksum (FCS).

Runts—Number of frames received that are smaller than the runt threshold.

Giants—Number of frames received that are larger than the giant threshold.

Policed discards—Number of frames that the incoming packet match code discarded because they were not recognized or not of interest. Usually, this field reports protocols that the JUNOS software does not handle.

Resource errors—Sum of transmit drops.

extensive

Output errors

Output errors on the interface. The following paragraphs explain the counters whose meaning might not be obvious:

Carrier transitions—Number of times the interface has gone from down to up. This number does not normally increment quickly, increasing only when the cable is unplugged, the far-end system is powered down and up, or another problem occurs. If the number of carrier transitions increments quickly (perhaps once every 10 seconds), the cable, the far-end system, or the PIC is malfunctioning.

Errors—Sum of the outgoing frame aborts and FCS errors.

Drops—Number of packets dropped by the output queue of the I/O Manager ASIC. If the interface is saturated, this number increments once for every packet that is dropped by the ASIC's RED mechanism.

MTU errors—Number of packets whose size exceeds the MTU of the interface.

Resource errors—Sum of transmit drops.

extensive

Serial media information

Information about the physical media:

Line protocol—eia530, eia530a, rs232, rs449, v.35, or x.21.

Resync history—Information about resynchronization events:

Sync loss count—Number of times the synchronization was lost.

Data signal—(X.21 and V.35) Information about the data signal:

Rx Clock—Receive clock status: OK (DTE is receiving the receive clock signal) or Not detected (receive clock signal is not being received).

Control signals—Information about modem control signals:

Local mode: DCE (data communication equipment) or DTE (data terminal equipment)

To DCE—Control signals that the Serial PIC sent to the DCE: DTR (Data Terminal Ready: up or down) or RTS (Request To Send: up or down.)

From DCE—Control signals that the Serial PIC received from the DCE: CTS (Clear To Send: up or down), DCD (Data Carrier Detect: up or down), DSR (Data Set Ready: up or down), or TM (Test Mode: up or down).

Clocking mode—Clocking used for the transmit clock:

dte—Transmit clock is generated by DTE.

dce—Transmit clock is generated by the DCE and is looped back as the transmit clock.

loop-timed—Receive clock from the DCE is looped back as the transmit clock.

Clock rate—Rate, in megahertz (MHz), at which the clock is configured.

Loopback—Configured loopback mode for the interface: dce-remote, dce-local, liu, local, or none.

Tx clock—Clocking phase of the transmit clock: invert (transmit clock polarity is inverted) or non-invert (transmit clock polarity is not inverted).

Line encoding—Type of line encoding used: nrz (nonreturn to zero) or nrzi (return to zero inverted).

Packet Forwarding Engine configuration

Information about the configuration of the Packet Forwarding Engine:

Destination slot—FPC slot number.

CoS transmit queue—The queue number and its associated user-configured forwarding class name.

bandwidth %—Percentage of bandwidth allocated to the queue.

Bandwidth bps—Bandwidth allocated to the queue (in bps).

buffer %—Percentage of buffer space allocated to the queue.

Buffer usec—Amount of buffer space allocated to the queue, in microseconds. This value is nonzero only if the buffer size is configured in terms of time.

Priority—Queue priority. Possible values are low and high.

Limit—Displayed if rate limiting is configured for the queue. Possible values are none and exact. If exact is configured, the queue transmits only up to the configured bandwidth, even if there is excess bandwidth available. If none is configured, the queue transmits beyond the configured bandwidth if bandwidth is available.

Input Errors	Input errors on the interface. The following paragraphs explain the counters whose meaning might not be obvious: `Errors`—Sum of the incoming frame aborts and FCS errors. `Drops`—Number of packets dropped by the input queue of the I/O Manager ASIC. If the interface is saturated, this number increments once for every packet that is dropped by the ASIC's RED mechanism. `Framing errors`—Number of packets received with an invalid frame checksum (FCS). `Runts`—Number of frames received that are smaller than the runt threshold. `Giants`—Number of frames received that are larger than the giant threshold. `Policed discards`—Number of frames that the incoming packet match code discarded because they were not recognized or not of interest.

`Output errors`	Output errors on the interface. The following paragraphs explain the counters whose meaning might not be obvious: `Carrier transitions`—Number of times the interface has gone from `down` to `up`. This number does not normally increment quickly, increasing only when the cable is unplugged, the far-end system is powered down and up, or another problem occurs. If the number of carrier transitions increments quickly (perhaps once every 10 seconds), the cable, the far-end system, or the PIC is malfunctioning. `Errors`—Sum of the outgoing frame aborts and FCS errors. `Drops`—Number of packets dropped by the output queue of the I/O Manager ASIC. If the interface is saturated, this number increments once for every packet that is dropped by the ASIC's RED mechanism. `MTU errors`—Number of packets whose size exceeds the MTU of the interface. `Resource errors`—Sum of transmit drops.	`extensive`

Clock rate—Rate, in megahertz (MHz), at which the clock is configured. `Loopback`—Configured loopback mode for the interface: dce-remote, dce-local, liu, local, or none. `Tx clock`—Clocking phase of the transmit clock: invert (transmit clock polarity is inverted) or non-invert (transmit clock polarity is not inverted). `Line encoding`—Type of line encoding used: nrz (nonreturn to zero) or nrzi (return to zero inverted).	`detail extensive`

Bandwidth bps—Bandwidth allocated to the queue (in bps). `buffer` %—Percentage of buffer space allocated to the queue. Buffer usec—Amount of buffer space allocated to the queue, in microseconds. This value is nonzero only if the buffer size is configured in terms of time. Priority—Queue priority. Possible values are low and high. Limit—Displayed if rate limiting is configured for the queue. Possible values are `none` and `exact`. If `exact` is configured, the queue transmits only up to the configured bandwidth, even if there is excess bandwidth available. If `none` is configured, the queue transmits beyond the configured bandwidth if bandwidth is available.	`extensive`
