IP Router Command Reference
Router Interface Commands
interface
Syntax [no] interface ip-int-name
Context config>router
Description This command creates a logical IP routing interface. When created, attributes like IP address, port, or
system can be associated with the IP interface.
Interface names are case-sensitive and must be unique within the group of IP interfaces defined for
config router interface. Interface names must not be in the dotted-decimal notation of an IP address
and must begin with a letter; for example, the name "1.1.1.1" is not allowed, but "int-1.1.1.1" is
allowed.
Show commands for router interfaces use either the interface names or the IP addresses. Ambiguity
can exist if an IP address is used both as an IP address and an interface name. Duplicate interface names
can exist in different router instances, although this is not recommended because it is confusing.
When a new name is entered, a new logical router interface is created. When an existing interface name
is entered, the user enters the router interface context for editing and configuration.
Although not a keyword, the interface name "system" is associated with the network entity (such as a
specific 7705 SAR), not a specific interface. The system interface is also referred to as the loopback
address.
The no form of the command removes the IP interface and all the associated configurations. The
interface must be administratively shut down before issuing the no interface command.
Default no interface
Parameters ip-int-name — the name of the IP interface. Interface names must be unique within the group of
110
defined IP interfaces for config router interface commands. An interface name cannot be in
the form of an IP address. If the string contains special characters (#, $, spaces, etc.), the entire
string must be enclosed within double quotes.
Values 1 to 32 characters (must start with a letter)
If the ip-int-name already exists, the context is changed to
maintain that IP interface. If the ip-int-name already exists as an
IP interface defined within the config router commands, an error
will occur and the context will not be changed to that IP interface.
If the ip-int-name does not exist, the interface is created and the
context is changed to that interface for further command
processing.
