Configuring a Gigabit Ethernet Interface with Quick Configuration

Add logical interfaces

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

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

MTU (bytes)

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

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

Per Unit Scheduler

Enables subunit queuing on Frame Relay or VLAN IQ interface.

Select the check box.

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 enabled.

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 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 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 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.
