Step Command Syntax Command Mode Purpose
1
interface interface CONFIGURATION Enter the keyword interface followed by the type of
interface and slot/port information:
• For a 1-Gigabit Ethernet interface, enter the keyword
GigabitEthernet followed by the slot/port information.
• For a Loopback interface, enter the keyword loopback
followed by a number from 0 to 16383.
• For the Management interface on the RPM, enter the
keyword
ManagementEthernet followed by the slot/
port information. The slot range is 0-1 and the port range
is 0.
• For a port channel interface, enter the keyword
port-channel followed by a number from 1 to 255 for
TeraScale and ExaScale, 1 to 32 for EtherScale.
• For a SONET interface, enter the keyword sonet
followed by the slot/port information.
• For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet followed by the slot/port
information.
• For a VLAN interface, enter the keyword vlan followed
by a number from 1 to 4094.
E-Series ExaScale platforms support 4094 VLANs
with FTOS version 8.2.1.0 and later. Earlier
ExaScale supports 2094 VLANS.

mask [secondary]
INTERFACE Configure a primary IP address and mask on the interface.
• ip-address mask: IP address must be in dotted decimal
format (A.B.C.D) and the mask must be in slash
prefix-length format (/24).
Add the keyword secondary if the IP address is the
interface’s backup IP address. You can configure up to eight
secondary IP addresses.
