shutdown), which reinitializes the protocol interfaces and MPLS LSPs associated with that IP
interface.
If a new address is entered while another address is still active, the new address wil be rejected.
Parameters ip-address — The IP address of the IP interface. The ip-addr portion of the address command
specifies the IP host address that will be used by the IP interface within the subnet. This address must
be unique within the subnet and specified in dotted decimal notation.
Values 1.0.0.0 - 223.255.255.255
/ — The forward slash is a parameter delimiter that separates the ipp-addr portion of the IP address
from the mask that defines the scope of the local subnet. No spaces are allowed between the ip-
addr, the “/” and the mask-length parameter. If a forward slash does not immediately follow the
ip-addr, a dotted decimal mask must follow the prefix.
mask-length — The subnet mask length when the IP prefix is specified in CIDR notation. When the
IP prefix is specified in CIDR notation, a forward slash (/) separates the ip-addr from the mask-
length parameter. The mask length parameter indicates the number of bits used for the network
portion of the IP address; the remainder of the IP address is used to determine the host portion of
the IP address. Allowed values are integers in the range 1-32. Note that a mask length of 32 is
reserved for system IP addresses.
Values 1-32
mask — The subnet mask in dotted decimal notation. When the IP prefix is not specified in CIDR
notation, a space separates the ip-addr from a traditional dotted decimal mask. The mask
parameters indicates the complete mask that will be used ina logical ‘AND’ function to derive
the local subnet of the IP address. Note that a mask of 255.255.255.255 is reserved for system IP
addresses.
Values 128.0.0.0 - 255.255.255.255
netmask — The subnet mask in dotted decimal notation.
Values 0.0.0.0 - 255.255.255.255 (nework bits all 1 and host bits all 0).

Description
This command creates a text description stored in the configuration file for a configuration context.
The no form of the command removes the description string from the context.
Default no description
Parameters description-string — The description character string. Allowed values are any string up to 80
characters long composed of printable, 7-bit ASCII characters. If the string contains special
character (#, $, space, etc.), the entire string must be enclosed within double quotes.
