Ethernet interface probe commands -- display system internal ethernet controlblock

Use display system internal ethernet controlblock to display the control block information of an interface, including the link layer parameter values.

Syntax

Centralized devices:

display system internal ethernet controlblock interface { interface-type interface-number }

Distributed devices in standalone mode:Centralized IRF devices:

display system internal ethernet controlblock interface { interface-type interface-number } slot slot-number [ cpu cpu-number ]

Parameters

interface interface-type interface-number: Specifies an interface by its type and number.

slot slot-number: Specifies a card by its slot number. (Distributed devices in standalone mode.)

slot slot-number: Specifies an IRF member device by its member ID. (Centralized IRF devices.) (IRF 3 incapable.)

slot slot-number: Specifies an IRF 2 member device by its member ID or specifies a PEX by its virtual slot number. (Centralized IRF devices.) (IRF 3 capable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. (Distributed devices in IRF mode.) (IRF 3 incapable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF 2 member device or specifies a PEX. The chassis-number argument represents the member ID of the IRF 2 member device or the virtual chassis number of the PEX. The slot-number argument represents the slot number of the card or PEX. (Distributed devices in IRF mode.) (IRF 3 capable.)

cpu cpu-number: Specifies a CPU by its number. This option is available only if multiple CPUs are available on the specified slot. Support for this keyword depends on the device model.

Parameters

global: Displays the global Ethernet characteristics. The global Ethernet characteristics match all packets on a device.

interface interface-type interface-number: Specifies an interface by its type and number.

slot slot-number: Specifies a card by its slot number. (Distributed devices in standalone mode.)

slot slot-number: Specifies an IRF member device by its member ID. (Centralized IRF devices.) (IRF 3 incapable.)

slot slot-number: Specifies an IRF 2 member device by its member ID or specifies a PEX by its virtual slot number. (Centralized IRF devices.) (IRF 3 capable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. (Distributed devices in IRF mode.) (IRF 3 incapable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF 2 member device or specifies a PEX. The chassis-number argument represents the member ID of the IRF 2 member device or the virtual chassis number of the PEX. The slot-number argument represents the slot number of the card or PEX. (Distributed devices in IRF mode.) (IRF 3 capable.)

cpu cpu-number: Specifies a CPU by its number. This option is available only if multiple CPUs are available on the specified slot. Support for this keyword depends on the device model.

Usage guidelines

The Ethernet module receives, decapsulates, sends, and encapsulates link layer packets. When an upper-layer application module (for example, STP or LLDP) needs to monitor and process protocol packets, the module performs the following operations:

· Specifies the monitoring scope (for example, packets on the specified interface or all packets on the device).

· Specifies the characteristics (for example, the specified Ethernet protocol type and the specified MAC) of the protocol packets to be monitored.

· Applies the characteristics to the Ethernet module.

The Ethernet module can match packets against the registered characteristics base during the specified phase (for example, RCV-MAC phase, RCV-LLC phase, and SND-L3IF phase). Packets matching the characteristics are processed by the current phase. Packets not matching the characteristics are processed by the next phase.
