show chassis ethernet-switch

(M10i, M40e, M120, M160, M320, and MX-series routers, and T-series routing platforms 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. For the routing matrix only, display information about each connected port on the Ethernet switch on the TX Matrix platform and its attached T640 routing nodes.

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.

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.

lcc number — (Routing matrix only) (Optional) Display information about the ports on the CB's Ethernet switch on a specified T640 routing node (or line-card chassis) that is connected to a TX Matrix platform. Replace number with a value from 0 through 3.

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

Output Fields

Table 55 lists the output fields for theshow chassis ethernet-switch command. Output fields are listed in the approximate order in which they appear.

Sample Output

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 platform only) LCC0 (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 platform, the speed is1000 Mb.
Duplex is	Duplex type of the Ethernet link: full orhalf.
Auto-negotiate is enabled	By default, both of the built-in Fast Ethernet ports on the M7i router Physical Interface Card (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.
