Configuring Ethernet Physical Interface Properties

To configure Fast Ethernet-specific physical interface properties, include the fastether-options statement at the [edit interfaces fe-fpc/pic/port] hierarchy level:

[edit interfaces fe-fpc/pic/port]link-mode (full-duplex | half-duplex);speed (10m | 100m);vlan-tagging;

Note: The speed statement applies to the management Ethernet interface (fxp0 or em0), the Fast Ethernet 12-port and 48-port Physical Interface Card (PIC) interfaces, the J Series Gigabit Ethernet uPIM interfaces and the MX Series Tri-Rate Ethernet copper interfaces. The Fast Ethernet, fxp0, and em0 interfaces can be configured for 10 Mbps or 100 Mbps (10m | 100m). The J Series Gigabit Ethernet uPIM interfaces and the MX Series Tri-Rate Ethernet copper interfaces can be configured for 10 Mbps, 100 Mbps, or 1 Gbps (10m | 100m | 1g). The 4-port and 8-port Fast Ethernet PICs support a speed of 100 Mbps only.

MX Series routers support Gigabit Ethernet automatic line sensing of MDI (Media Dependent Interface) and MDIX (Media Dependent Interface with Crossover) port connections. MDI is the Ethernet port connection typically used on network interface cards (NIC). MDIX is the standard Ethernet port wiring for hubs and switches. This feature allows MX Series routers to automatically detect MDI and MDIX connections and configure the router port accordingly. You can disable this feature by using the no-auto-mdix statement at the [edit interfaces ge-fpc/pic/port] hierarchy level.

Note: Junos OS supports Ethernet host addresses with no subnets. This enables you to configure an Ethernet interface as a host address (that is, with a network mask of /32), without requiring a subnet. Such interfaces can serve as OSPF point-to-point interfaces, and MPLS is also supported.

To configure physical interface properties specific to Gigabit Ethernet and 10-Gigabit Ethernet, include the gigether-options statement at the [edit interfaces ge-fpc/pic/port] or [edit interfaces xe-fpc/pic/port] hierarchy level:

[edit interfaces ge-fpc/pic/port]
gigether-options {802.3ad aex (primary | backup);auto-negotiation | no-auto-negotiation) remote-fault <local-interface-online | local-interface-offline>;(flow-control | no-flow-control);ignore-l3-incompletes;(loopback | no-loopback);no-auto-mdix;source-address-filter {mac-address;}(source-filtering | no-source-filtering);}

Additionally, for 10-Gigabit Ethernet DWDM-specific physical interface properties, include the optics-options statement at the [edit interfaces ge-fpc/pic/port] hierarchy level:

[edit interfaces ge-fpc/pic/port]

To configure Gigabit Ethernet IQ-specific physical interface properties, include the gigether-options statement at the [edit interfaces ge-fpc/pic/port] hierarchy level. These statements are supported on 10-Gigabit Ethernet IQ2 and IQ2-E PIC. Some of these statements are also supported on Gigabit Ethernet PICs with small form-factor pluggable transceivers (SFPs) (except the 10-port Gigabit Ethernet PIC and the built-in Gigabit Ethernet port on the M7i router). For more information, see Example: Configuring Gigabit Ethernet Interfaces.

[edit interfaces ge-fpc/pic/port]flexible-vlan-tagging;
gigether-options {802.3ad aex (primary | backup);auto-negotiation | no-auto-negotiation) remote-fault <local-interface-online | local-interface-offline>;(flow-control | no-flow-control);ignore-l3-incompletes;(loopback | no-loopback);(source-filtering | no-source-filtering);ethernet-switch-profile {(mac-learn-enable | no-mac-learn-enable);tag-protocol-id [tpids ];ethernet-policer-profile {input-priority-map {ieee802.1p premium [values ];}output-priority-map {classifier {premium {forwarding-class class-name {loss-priority (high | low);}}}}policer cos-policer-name {aggregate {bandwidth-limit bps;burst-size-limit bytes;}premium {bandwidth-limit bps;burst-size-limit bytes;}}}}native-vlan-id number;}

To configure 10-Gigabit Ethernet physical interface properties, include the lan-phy or wan-phy statement at the [edit interfaces xe-fpc/pic/port framing] hierarchy level. For more information, see 10-Gigabit Ethernet Framing Overview.

[edit interfaces]
xe-0/0/0 {framing {(lan-phy | wan-phy);}}

To configure OAM 802.3ah support for Ethernet interfaces, include the oam statement at the [edit protocols] hierarchy level.

oam {ethernet {link-fault-management {interfaces {interface-name{pdu-interval interval;link-discovery (active | passive);pdu-threshold count;}}}}}

To configure Gigabit Ethernet IQ-specific logical interface properties, include the input-vlan-map, output-vlan-map, layer2-policer, and vlan-tags statements:

layer2-policer {input-policer policer-name;input-three-color policer-name;output-policer policer-name;output-three-color policer-name;}
vlan-tags inner tpid.vlan-id outer tpid.vlan-id;

You can include these statements at the following hierarchy levels:

  • [edit interfaces interface-name unit logical-unit-number]
  • [edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]

To configure aggregated Ethernet-specific physical interface properties, include the aggregated-ether-options statement at the [edit interfaces aex] hierarchy level:
