Chapter 4: Configuring Upper-Layer Protocols over Static Ethernet Interfaces
Ethernet interfaces, except for bridged Ethernet interfaces, support multinetting; that is,
adding more than one IP address to an IP interface. If you want to add multiple IP
addresses to a single IP interface, use the ip address command with the secondary
keyword, which is described in the chapter Configuring IP in JunosE IP, IPv6, and IGP
Configuration Guide.
This section explains how to use the show commands to display the physical
characteristics and the configured settings for Ethernet interfaces.
NOTE: The E120 and E320 routers output for monitor and show commands
is identical to output from other E Series routers, except that the E120 and
E320 routers output also includes information about the adapter identifier
in the interface specifier (slot/adapter/port).
You can use various show commands to monitor upper-layer protocols. For more
information, see:
"Configuring Point-to-Point Protocol over Ethernet" on page 371

Use to display the status of Fast Ethernet interfaces, VLAN subinterfaces, or S-VLAN
subinterfaces.
You can specify the following keywords:
delta—Specifies that baselined statistics are to be shown
brief—Displays the operational status of all configured interfaces
Field descriptions
FastEthernet interfaceSpecifier—Status of the hardware on this interface
up—Hardware is operational
down—Hardware is not operational
Administrative status—Operational state that you configured for this interface
up—Interface is enabled
down—Interface is disabled
Hardware—Type of MAC device on this interface
