Field Description<br />

Unique number for use by <strong>Juniper</strong> <strong>Networks</strong> technical support only.<br />

Encapsulation being used on the physical interface.<br />

Maximum transmission unit size on the physical interface.<br />

Type of link connection configured for the physical interface: Full-duplex or<br />

Half-duplex<br />

Speed at which the interface is running.<br />

Loopback status: Enabled or Disabled. If loopback is enabled, type of loopback:<br />

Local or Remote.<br />

Source filtering status: Enabled or Disabled.<br />

10-Gigabit Ethernet interface operating in Local Area Network Physical Layer<br />

Device (LAN PHY) mode. LAN PHY allows 10-Gigabit Ethernet wide area links<br />

to use existing Ethernet applications.<br />

10-Gigabit Ethernet interface operating in Wide Area Network Physical Layer<br />

Device (WAN PHY) mode. WAN PHY allows 10-Gigabit Ethernet wide area links<br />

to use fiber-optic cables and other devices intended for SONET/SDH.<br />

Unidirectional link mode status for 10-Gigabit Ethernet interface: Enabled or<br />

Disabled for parent interface; Rx-only or Tx-only for child interfaces.<br />

Flow control status: Enabled or Disabled.<br />

(Gigabit Ethernet interfaces) Autonegotiation status: Enabled or Disabled.<br />

(Gigabit Ethernet interfaces) Remote fault status:<br />

• Online—Autonegotiation is manually configured as online.<br />

• Offline—Autonegotiation is manually configured as offline.<br />
