Specifying the Interface Address on a SPA
SPA interface ports begin numbering with "0" from left to right. Single-port SPAs use only the port number
0. To configure or monitor SPA interfaces, you need to specify the physical location of the SIP, SPA, and
interface in the CLI. The interface address format is slot/subslot/port, where:
• slot—Specifies the chassis slot number in the Cisco ASR 1000 Series Router where the SIP is installed.
• subslot—Specifies the secondary slot of the SIP where the SPA is installed.
OL-14127-17
Purpose
• dhcp—Specifies that IP addresses will be assigned dynamically using DHCP.
• client-id interface-name—Specifies the client identifier. The interface-name
sets the client identifier to the hexadecimal MAC address of the named
interface.
• hostname host-name—Specifies the hostname for the DHCP purposes. The
host-name is the name of the host to be placed in the DHCP option 12 field.
(As Required) Specifies the maximum packet size for an interface, where:
• bytes— Specifies the maximum number of bytes for a packet.
The default is 1500 bytes; the range is 1500 to 9216.
(Required for HSRP Configuration Only) Creates (or enables) the HSRP group
using its number and virtual IP address, where:
• (Optional) group-number—Specifies the group number on the interface for
which HSRP is being enabled. The range is 0 to 255; the default is 0. If there
is only one HSRP group, you do not need to enter a group number.
• ( Optional on all but one interface if configuring HSRP )
ip-address—Specifies the virtual IP address of the hot standby router
interface. You must enter the virtual IP address for at least one of the
interfaces; it can be learned on the other interfaces.
• (Optional) secondary—Specifies the IP address is a secondary hot standby
router interface. If neither router is designated as a secondary or standby
router and no priorities are set, the primary IP addresses are compared and
the higher IP address is the active router, with the next highest as the standby
router.
This command enables HSRP but does not configure it further. For additional
information on configuring HSRP, refer to the HSRP section of the Cisco IP
Configuration Guide publication that corresponds to your Cisco IOS software
release.
