Configuring a 10-Gigabit Ethernet Interface with Quick Configuration

To configure properties on a 10-Gigabit Ethernet interface:

  1. From the Quick Configuration page, as shown in Figure 8, select the 10-Gigabit Ethernet interface you want to configure.

    The properties you can configure on a 10-Gigabit Ethernet interface are displayed, as shown in Figure 13.

    Figure 13: 10-Gigabit Ethernet Interfaces Quick Configuration Page

  2. Enter information into the Quick Configuration page, as described in Table 91.
  3. Click one of the following buttons:

Table 91: 10-Gigabit Ethernet Quick Configuration Page Summary

Field

Function

Your Action

Logical Interfaces

Add logical interfaces

Defines one or more logical units that you connect to this physical 10-Gigabit Ethernet interface. You must define at least one logical unit for a 10-Gigabit Ethernet interface.

Click Add.

Logical Interface Description

(Optional) Describes the logical interface.

Type a text description of the logical interface to more clearly identify it in monitoring displays.

IPv4 Addresses and Prefixes

Specifies one or more IPv4 addresses for the interface.

  1. Type one or more IPv4 addresses and prefixes. For example:

    10.10.10.10/24

  2. Click Add.
  3. Click OK.

To delete an IP address and prefix, select them in the Source Addresses and Prefixes box, then click Delete.

Physical Interface Description

(Optional) Adds supplementary information about the physical 10-Gigabit Ethernet interface.

Type a text description of the 10-Gigabit Ethernet interface to more clearly identify it in monitoring displays.

MTU (bytes)

Specifies the maximum transmission unit size for the 10-Gigabit Ethernet interface.

Type a value between 256 and 9192 bytes. The default MTU for 10-Gigabit Ethernet interfaces is 1504.

Clocking

Specifies the source of the transmit clock on the 10-Gigabit Ethernet interface.

From the list, select one of the following:

  • internal—Sets the router's internal stratum 3 clock as the reference clock.
  • external—Sets the external clock source provided by the data communication equipment (DCE) as the reference clock.

Per Unit Scheduler

Enables subunit queuing on Frame Relay or virtual LAN intelligent queuing (IQ) interfaces.

Select the check box.

Framing Mode

Framing

Specifies the framing mode for the Ethernet interface.

From the list, select one of the following:

  • LAN-mode—Configures the interface as an 802.3ae 10-Gbps LAN PHY interface.
  • WAN-mode—Configures the interface as an 802.3ae 10-Gbps WAN PHY interface.

For more information about the LAN PHY and WAN PHY modes, see the JUNOS Network Interfaces Configuration Guide

Sonet Options (available if WAN PHY framing is enabled)

Loopback Mode

Specifies the loopback mode for troubleshooting physical circuit problems.

You can determine whether a problem exists in the interface or the network by checking the error counters in the output of the show interfaces interface-name extensive command.

From the list, select one of the following:

  • local—Use this mode to loop outgoing packets within the 10-Gigabit Ethernet interface just before the data reaches the transceiver. Local loopback helps you verify whether the interface is operating properly.
  • remote—Use this mode to loop incoming packets back to the sending router before the data reaches the frame. This mode sends incoming traffic unchanged back to the sending router. Remote loopback helps you verify whether a problem exists in the network.

Path Trace

Specifies the SONET path trace identifier, which is a text string that identifies the circuit.

The path trace identifier is transmitted to the router at the other end of the link to help that router diagnose misconfigurations and network errors when it does not receive the transmitted path trace message.

If you do not configure an identifier, the JUNOS software automatically generates one from the name of the interface through which the path trace message is transmitted—for example, xe-0/0/0.

Type the path trace identifier.

If the path trace string contains spaces, enclose it in quotation marks. A common convention is to use the circuit identifier as the path trace identifier.

Note: Path trace identifiers longer than 16 bytes might be truncated. You can prevent truncation by configuring an identifier that is shorter than 16 bytes long.

Gigabit Ethernet Options

Flow Control

Enables or disables flow control.

Select Yes to enable flow control to regulate the amount of traffic sent out of the interface, or select No to disable flow control and permit unrestricted traffic. Flow control is disabled by default.

Loopback

Enables or disables the loopback option.

Select Yes to enable the loopback diagnostic option, or select No to disable the loopback option. By default, loopback is disabled.

Source Filtering

Enables or disables source filtering. Enabling source filtering blocks all incoming packets to the interface.

For more information, see the JUNOS Network Interfaces Configuration Guide

Select Yes to enable source filtering, or select No to disable the source filtering. By default, source filtering is disabled.

Note: If you disable source filtering, the source MAC address filtering is also disabled.

Auto Negotiation

Enables or disables autonegotiation.

Select Yes to enable autonegotiation, or select No to disable it. By default, autonegotiation is disabled.

Auto Negotiation Remote Fault

Indicates the autonegotiation remote fault value.

Select the autonegotation remote fault value from the list of options given. This field is enabled only if autonegotiation is enabled.

Source MAC Address Filters

Displays the list of media access control (MAC) addresses from which you want to receive packets on this interface.

Note: To enable source MAC address filtering, first enable source filtering by selecting the Yes check box next to Source Filtering.

To add MAC addresses, type them in the boxes above the Add button, then click Add.

To delete a MAC address, select it in the Source Addresses box, then click Delete.

802.3ad

Specifies a “bundle” of 10-Gigabit Ethernet interfaces on this router with which to share traffic.

To use this feature, you must already have configured an aggregate Ethernet interface, by specifying the link number as a physical device and then associating a set of ports that have the same speed and are in full-duplex mode.

Type an aggregated Ethernet interface value—for example, ae0. Aggregated Ethernet interface names range from ae0 through ae15.

Note: The J-Web interface displays error messages if you enter an incorrect value.

For more information, see the JUNOS Network Interfaces Configuration Guide

Tag Protocol ID

Displays a list of IEEE 802.1Q Tag Protocol Identifier (TPID) values. The TPIDs identify frames that are to be processed as virtual LAN (VLAN)-tagged frames.

To use this feature, you must already have enabled VLAN tagging. VLAN tags enable you to channelize an Ethernet interface into multiple logical interfaces, allowing many hosts to be connected to the same 10-Gigabit Ethernet switch.

To add a TPID, type it in the boxes above the Add button, then click Add.

To delete a TPID, select it in the box, then click Delete.

Each 10-Gigabit Ethernet port can have up to eight TPIDs.

For more information about TPIDs and VLAN tagging, see the JUNOS Network Interfaces Configuration Guide.

MAC Learning

Enables or disables source and destination MAC address learning dynamically.

Select Yes to enable dynamic MAC address learning, or select No to disable it. By default, dynamic MAC address learning is disabled.
