Internet address
The Internet address is the 32-bit IP address for the specified logical interface. The address is in standard dotted-decimal (octet) notation: xxx.xxx.xxx.xxx.
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.
Broadcast or 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.
When you assign an IP address to a logical interface on a point-to-point media such as HIPPI or ATM, the destination address is entered in the broadcast address field.
Note that any entry in the broadcast address field for HIPPI or ATM makes it a point-to-point connection to that address. If you remove the broadcast address, you create a nonbroadcast, multiaccess (NBMA) interface.
Argument field
This field is optional for SP Switch Router Adapter cards. The argument field specifies a Maximum Transmission Unit (MTU) value different from the coded default value of 65520. When the command grifconfig runs, it passes the arguments to the ifconfig command that it spawns.
Default MTU values
Default MTUs for SP Switch Router media are:
•SP Switch Router Adapter: 65520 bytes
•HIPPI: 65280 bytes
•FDDI: 4352 bytes
•ATM OC-3c: 9180 bytes
•ATM OC-12c: 9180 bytes
•10/100Base-T: 1500 bytes
