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).

Flow Control TX is Enabled (or Disabled)

Flow control in the transmit direction is enabled (or disabled). Flow control regulates the flow of packets from the switch to the remote side of the connection.

Flow Control RX is Enabled (or Disabled)

Flow control in the receive direction is enabled (or disabled). Flow control regulates the flow of packets from the remote side of the connection to the switch.
