Description This command assigns an IP address IP subnet, to an IES IP router interface. Only one IP address can
be associated with an IP interface. An IP address must be assigned to each IES IP interface. An IP
address and a mask are used together to create a local IP prefix. The defined IP prefix must be unique
within the context of the routing instance. It cannot overlap with other existing IP prefixes defined as
local subnets on other IP interfaces in the same routing context within the 7210 SAS.
The IP address for the interface can be entered in either CIDR (Classless Inter-Domain Routing) or
traditional dotted decimal notation. The show commands display CIDR notation and is stored in
configuration files.
By default, no IP address or subnet association exists on an IP interface until it is explicitly created.
Use the no form of this command to remove the IP address assignment from the IP interface. When
the no address command is entered, the interface becomes operationally down.
The operational state is a read-only variable and the only controlling variables are the address and
admin states. The address and admin states are independent and can be set independently. If an
interface is in an adminstratively up state and an address is assigned, it becomes operationally up.
ip-address — The IP address of the IP interface. The ip-address 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. Allowed values are IP
addresses in the range 1.0.0.0 – 223.255.255.255 (with support of /31 subnets).
/ — The forward slash is a parameter delimiter and separates the ip-address portion of the IP address
from the mask that defines the scope of the local subnet. No spaces are allowed between the ip-
address, the “/” and the mask-length parameter. If a forward slash is not immediately following
the ip-address, 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-address 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 0 – 30. Note that a mask length
of 32 is reserved for system IP addresses.
mask — The subnet mask in dotted decimal notation. When the IP prefix is not specified in CIDR
notation, a space separates the ip-address from a traditional dotted decimal mask. The mask
