Interface name
The SP Switch Router interface name has five components that describe an individual interface
in terms of its physical slot location in the chassis, and its specific and virtual locations on a
media card.
In a 4-card SP Switch Router, model 04S, the SP Switch Router Adapter card interface names
look like these: gt000, gt010, gt020, gt030 (only the slot # changes, 0 – 4).
Figure 2-5 defines the components in the SP Switch Router Adapter card interface name:

Internet address
The Internet address is the 32-bit IP address for the specified logical interface. Enter this
address in standard dotted-decimal (octet) notation: xx.xx.xx.xx. This value must match
any entered into /etc/grdev1.conf.
Netmask
Netmask is the 32-bit address for the logical IP network on the physical network to which the
specific SP Switch Router or media card physical interface is attached. The netmask is entered
in standard dotted-decimal (octet) notation. If no destination/broadcast address is supplied, a
netmask is required. This value must match any entered into /etc/grdev1.conf.
Broadcast / destination address
The broadcast or destination address is the 32-bit address for this network. Enter the broadcast
or destination address in standard dotted-decimal (octet) notation. When a broadcast IP address
is assigned to a logical interface, the netmask value is ignored. A dash (-) can be entered in the
netmask column, or it can be left blank.
The connection of the SP Switch Router Adapter card to the SP system is point-to-multipoint.
