Description

Display status information for the specified abstracted fabric (af) interface.

Note:

  • Starting in Junos OS Release 18.3R1, the show interfaces af-interface-name output provides transmit statistics of each Packet Forwarding Engine peer list on a given af interface, in addition to the physical interface statistics.

  • Starting from Junos OS Release 21.4R1, the show interface af-name command does not display the information about the load balancing of transmit traffic on each peer GNF Forwarding Element (FE). For this information, use the show interfaces lb-stats af-name command.

Options

brief | detail | extensive | terse

(Optional) Display the specified level of output.

descriptions

(Optional) Display interface description strings.

media

(Optional) Display media-specific information about network interfaces.

snmp-index snmp-index

(Optional) Display information for the specified SNMP index of the interface.

statistics

(Optional) Display static interface statistics.

detail extensive none

Hardware address

Hardware MAC address.

detail extensive none

Last flapped

Date, time, and how long ago the interface went from down to up. The format is Last flapped: year-month-day hour:minute:second:timezone (hour:minute:second ago). For example, Last flapped: 2002-04-26 10:52:40 PDT (04:33:20 ago).

detail extensive none

Statistics last cleared

Time when the statistics for the interface were last set to zero.

detail extensive

Traffic statistics

Number and rate of bytes and packets received and transmitted on the physical interface.

  • Input bytes—Number of bytes received on the interface.

  • 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

IPv6 transit statistics

Number of IPv6 transit bytes and packets received and transmitted on the interface if IPv6 statistics tracking is enabled.

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 terminates and FCS errors.

  • Drops—Number of packets dropped by the input queue.

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

  • Runts—Number of frames received that are smaller than the runt 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 Junos OS 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.

  • Errors—Sum of the outgoing frame terminates and FCS errors.

  • Drops—Number of packets dropped by the output queue.

    Note:

  • MTU errors—Number of packets whose size exceeded the MTU of the interface.

  • Resource errors—Sum of transmit drops.

Collapsed Forwarding Optimized Statistics

This section has the following subsections to display fabric optimization information.

  • Optimal Packets—shows the packets that are already forwarded to optimal Packet Forwarding Engine based on the abstracted fabric interface load balancing.

  • Non-optimal Packets—By default, these packets are forwarded to the non-optimal Packet Forwarding Engine by abstracted fabric interface. If you have configured the optimize mode using the command set chassis network-slices guest-network-functions gnf id collapsed-forward optimize, this section shows the packets that are optimized because of this configuration. If you have configured the monitor mode using the command set chassis network-slices guest-network-functions gnf id collapsed-forward monitor, this section shows non-optimal packets.
