show interfaces extensive

Syntax

Description

Display extensive information about all interfaces configured on the router.

Note:
  • At some times, the cumulative byte counters displayed with the show interfaces extensive command on the 10-Gigabit Ethernet MPC with SFP+ is not always increasing and cumulative and does not give the correct results. There is a time lag in collecting these statistics, during which the display might decrease or go from a nonzero number to zero. Eventually, the counter will display the correct result.

  • When the show interfaces extensive command is executed on a router with an MPC or a T4000 Type 5 FPC, the Input packet rejects counter of the Filter statistics field also displays statistics related to the following packet errors:

    • Invalid VLAN range

    • Tagged packet received on an untagged interface

  • When the show interfaces extensive command is executed on an interface that is configured on a T4000 Type 5 FPC, the IPv6 transit statistics field displays:

    • Total statistics (sum of transit and local statistics) at the physical interface level

    • Transit statistics at the logical interface level

  • When the show interfaces extensive command is executed on an aggregate interface in a T1600 Core Router, the IPv6 Input bytes is displayed for an aggregate interface. However, the IPv6 Input bytes is always zero on a member link of an aggregated bundle even when there is IPv6 transit traffic on the member link. This is because the logical interface index of the aggregate logical interface is updated but not the logical interface of the member links in the channel lookup table.

  • The Output packets field under the Traffic statistics section in the output of the show interfaces extensive command includes both IPv4 and IPv6 packets. For example, in a scenario in which both IPv4 and IPv6 packets are being mirrored on the same interface and when you deactivate an IPv4 port-mirroring instance on the chassis, the output of the show interfaces extensive command shows a value in the Output packets field of the Traffic statistics section, which is the value of IPv6 packets that are mirrored and not of the IPv4 packets. This behavior is expected.

  • For IQ2 PIC interfaces, the output of the show interfaces extensive command displays byte statistics that includes Layer 2 headers.

  • If there are active OTN defects when an ISSU is performed, and the defect persists after the upgrade completes, the OTN alarm count is incremented by 1. For example, if an OTN alarm is active with a count of 1 and the defect remains after ISSU, the alarm count is incremented to 2. This behavior is expected.

  • On Junos OS Evolved, the show interfaces extensive output displays zero for all loopback interface (lo0) statistics.

Output Fields

For more information, see the output fields table for the particular interface type in which you are interested. For information about destination class and source class statistics, see the “Destination Class Field” section and the “Source Class Field” section under Common Output Fields Description. For sample output for specific interfaces, see the other topics in this collection.

Sample Output

show interfaces extensive (Circuit Emulation)

If a Circuit Emulation (CE) PIC is configured for SAToP pseudowire, then pseudowire statistics are displayed in the CE information section of the show interface extensive output. If SAToP pseudowire is not configured on the CE PIC, then all CE information counters display 0 (zero).

When an ASIC is wedged, the interfaces are brought down along with the IFD. The reason for the link down is displayed as ASIC-Error in the Device flags.

The output fields for the show interfaces interface extensive command remains the same for 12-port 10-Gigabit Ethernet LAN/WAN PIC with SFP+ (PF-12XGE-SFPP), 24-port 10-Gigabit Ethernet LAN/WAN PIC with SFP+ (PF-24XGE-SFPP), and 100-Gigabit Ethernet Type 5 PIC with CFP (PF-1CGE-CFP).

show interfaces extensive (Aggregated Ethernet)

show interfaces extensive (EX4400-48T, EX4400-48P, EX4400-24T, EX4400-24P)

Starting in Junos OS Release 21.1R1, the 1Gbps or 100Mpbs port switches to low power idle (LPI) mode based on the following conditions:

  • When a port operates at 1 Gbps speed and no traffic is either received or transmitted, then the port enters LPI mode. If the 1Gbps port transfers unidirectional or bidirectional traffic, then the port will not enter LPI mode.
  • • When a port operates at 100 Mbps speed, the port switches to LPI mode, based on the direction of the traffic. The show interfaces interface-name extensive command displays RX LPI when no RX traffic and TX LPI when no TX traffic.

You can view the interface that is in low power idle mode, by executing the show interfaces interface-name extensive command. The output field, IEEE 802.3az Energy Efficient Ethernet displays the status of the LPI mode.
