Release Information

Command introduced before JUNOS Release 7.4.

sfc option introduced for the TX Matrix Plus router in JUNOS Release 9.6.

Description

(M10i, M40e, M120, M160, M320, MX Series, and T Series routers only) Display information about the ports on the Control Board (CB) Ethernet switch.

Options

none — Display information about each connected port on the Ethernet switch. On a TX Matrix router, display information about each connected port on the Ethernet switch on the TX Matrix router and its attached T640 routers. On a TX Matrix Plus router, display information about each connected port on the Ethernet switch on the TX Matrix Plus router and its attached T1600 routers.

errors — (Optional) Display the numbers and types of errors accumulated on all ports of the Ethernet switch.

errors port — (Optional) Display the numbers and types of errors accumulated on the specified port (0 through 15) of the Ethernet switch. On the TX Matrix router, replace port with a value from 0 through 15. On the TX Matrix Plus router, replace port with a value from 0 through 27.

errors switch number — (TX Matrix Plus routers only) (Optional) Display the numbers and types of errors accumulated on the specified switch. Replace number with a value from 0 through 2.

lcc number — (TX Matrix and TX Matrix Plus routers only) (Optional) On a TX Matrix router, display information about the ports on the CB's Ethernet switch on a specified T640 router (or line-card chassis) that is connected to a TX Matrix router. On a TX Matrix Plus router, display information about the ports on the CB's Ethernet switch on a specified T1600 router (or line-card chassis) that is connected to a TX Matrix Plus router. Replace number with a value from 0 through 3.

scc — (TX Matrix router only) (Optional) Display information about the ports on the CB's Ethernet switch on the TX Matrix router (or switch-card chassis).

sfc number — (TX Matrix Plus router only) (Optional) Display information about the ports on the CB’s Ethernet switch on the TX Matrix Plus router (or switch-fabric chassis). Replace number with 0.

statistics — (Optional) Display traffic statistics for each connected port on the Ethernet switch.

statistics port — (Optional) Display traffic statistics for the specified port on the Ethernet switch. On the TX Matrix router, replace port with a value from 0 through 25. On the TX Matrix Plus router, replace port with a value from 0 through 27.

statistics switch number — (TX Matrix Plus routers only) (Optional) Display traffic statistics for the specified Ethernet switch number. Replace number with a value from 0 through 2.

Output Fields

Table 55: show chassis ethernet-switch Output Fields

Field Name

Field Description

Link is good on port n connected to device

or

Link is good on FE port n connected to device

Information about the link between each port on the CB's Ethernet switch and one of the following devices:

  • FPC0 (Flexible PIC Concentrator 0) through FPC7
  • Local controller
  • Other RE (on a system with two Routing Engines)
  • SPMB (Switch Processor Mezzanine Board)
  • (TX Matrix router only) LCCO (line-card chassis 0) through LCC3

Speed is

Speed at which the Ethernet link is running: 10 Mb or 100 Mb. When the device is Other RE on the TX Matrix router, the speed is 1000 Mb.

Duplex is

Duplex type of the Ethernet link: full or half.

Auto-negotiate is enabled

By default, both of the built-in Fast Ethernet ports on the M7i router PIC autonegotiate whether to operate at 10 Mbps or 100 Mbps. All other interfaces automatically choose the correct speed based on the PIC type and whether the PIC is configured to operate in multiplexed mode (using the no-concatenate statement at the [edit chassis] hierarchy level, as described in the JUNOS System Basics Configuration Guide).

MLT3

Number of multilevel threshold-3 (MLT-3) Fast Ethernet errors detected.

Accumulated error counts for port n connected to device FPCn: (error output only)

Lock

Number of lock errors detected.

Xmit

Number of transmission errors detected.

ESD

Number of electrostatic discharge (ESD) errors detected.

False Carrier

Number of false carrier errors detected.

Disconnects

Number of disconnect errors detected.

FX mode

Number of errors detected on an Ethernet link over optical fiber.

Statistics for port n connected to device FPCn (statistics output only)

TX Unicast packets

Number of unicast packets sent.

TX Multicast packets

Number of multicast packets sent.

TX Broadcast packets

Number of broadcast packets sent.

TX Late collisions

Number of packets aborted during sending because of collisions after 64 bytes.

TX Excessive collisions

Number of packets not sent because of too many collisions.

TX Dropped packets

Number of transmitted packets that were dropped.

RX Unicast packets

Number of unicast packets received.

RX Multicast packets

Number of multicast packets received.

RX Broadcast packets

Number of broadcast packets received.

RX FCS Errors

Number of packets discarded because of frame check sequence errors.

RX Alignment Errors

Number of incomplete octets received.

RX Dropped Packets

Number of incoming packets that were dropped.

RX Fragments

Number of fragmented packets received.

RX Symbol Errors

Number of symbols received that the router did not correctly decode.
