Using the CLI 226
When listed in command line output, port channel interfaces are preceded by
the characters Po.
Tunnel Interfaces
Tunnel interfaces are represented in the CLI by the keyword tunnel followed
by the variable tunnel-id, which can assume values from 0–7.
VLAN Routing Interfaces
VLAN interfaces are represented in the CLI by the keywords interface vlan
followed by the variable vlan-id, which can can assume values from 1-4093. A
VLAN routing interface will typically have an IP address assigned, either via
DHCP or a static assignment or, in the case of IPv6, auto assignment of a link
local address.
Operating on Multiple Interfaces (Ranges)
The CLI allows the user to operate on multiple interfaces in one operation.
The guidelines are as follows for range operation:
• The range key word is used to identify that an interface range specifier
follows.
– An interface range specifier consists of an interface identifier followed
by an optional range parameter. The interface type may be a physical
interface or a logical interface (port channel or VLAN) as described in
the Interface Naming Conventions section.
• The range parameter may be written in the following manner:
(#-#) — a range from a particular interface to another higher-numbered
interface (inclusive). For example, 1/0/1-10 indicates that the operation
applies to the physical interfaces 1 to 10 in slot 0 on unit 1. The number to
the left of the hyphen must always be less than or equal to the number to
the right of the hyphen, e.g. interface range Gi1/0/10-1 is not valid.
(#, #, #) — a list of interfaces. For example, (1/0/1, 1/0/1,1/0/3, 1/0/5)
indicates that the operation applies to the physical interfaces 1, 3, and 5 on
unit 1. The interfaces may or may not be consecutive, nor must the
interfaces be of the same type.
