Syntax

Description

(QFX3000-G QFabric systems only) Display Ethernet switch information for the front card Flexible Port Concentrators (FPCs) in an Interconnect device.

Options

none

Display Ethernet switch information about each connected port on each online FPC in the Interconnect device.

detail

(Optional) Display detailed status information for all FPCs or for the FPC in the specified slot in the Interconnect device.

port number

(Optional) Display Ethernet switch information about a specific port on an FPC in the Interconnect device.

slot number

(Optional) Display Ethernet switch information about an FPC in a specific slot in the Interconnect device.

Output Fields

Table 1 lists the output fields for the show chassis ethernet-switch interconnect-device fpc command. Output fields are listed in the approximate order in which they appear.

Table 1: show chassis ethernet-switch interconnect-device fpc Output Fields

Field Name

Field Description

Link is good on port n connected to device

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

  • FWD-SWITCH-0

  • FWD-SWITCH-1

  • CB0

  • CB1

Speed is

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

Duplex is

Duplex type of the Ethernet link: full or half.

Autonegotiate is Enabled (or Disabled)

By default, built-in Fast Ethernet ports on a 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 OS System Basics Configuration Guide).
