Release Information
Command modified in Release 9.5 of Junos OS.
Description
Display status information and statistics about interfaces on J Series and SRX Series devices running Junos OS.
Options
interface-name —(Optional) Display standard information about the specified interface. Following is a list of typical interface names. Replace pim with the PIM slot and port with the port number. For a complete list, see the Junos OS Interfaces Configuration Guide for Security Devices.
- at- pim/0/port—ATM-over-ADSL or ATM-over-SHDSL interface.
- br-pim/0/port—Basic Rate Interface for establishing ISDN connections.
- ce1-pim/0/ port—Channelized E1 interface.
- cl-0/0/8—3G wireless modem interface for SRX210 devices.
- ct1-pim/0/port—Channelized T1 interface.
- dl0—Dialer Interface for initiating ISDN and USB modem connections.
- e1-pim/0/port—E1 interface.
- e3-pim/0/port—E3 interface.
- fe-pim/0/port—Fast Ethernet interface.
- ge-pim/0/port—Gigabit Ethernet interface.
- se-pim/0/port—Serial interface.
- t1-pim/0/port—T1 (also called DS1) interface.
- t3-pim/0/port—T3 (also called DS3) interface.
- wx-slot/0/0—WAN acceleration interface, for the WXC Integrated Services Module (ISM 200).
