3.10.2 Method 2: Edit /etc/grifconfig.conf - Optional

Edit the /etc/grifconfig.conf file to assign an IP address to each logical SP Switch Router interface. You can also provide other information about the logical IP network to which that interface is physically attached.

Each logical interface is identified in /etc/grifconfig.conf by these properties:

Its interface name (an SP Switch Router convention, defined below)

Its Internet address

Its netmask

Its broadcast/destination address

An argument field

The format for an entry in the /etc/grifconfig.conf file is:

# name

address

netmask

broad_dest

arguments

gt030

192.168.14.4

255.255.255.0

-

mtu 65520

Remember that if you enter configuration information into SP Switch Router configuration files, you also need to access the SMIT panels and reenter information those panels require.

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 the SP Switch Router, the SP Switch Router Adapter card interface names look like this: gt000, gt030, gt0a0, gt0f0 (only the slot number, represented as a hexadecimal digit, changes).

Figure 35 shows the definitions of the components that comprise the SP Switch Router Adapter card interface names:

g t 0 y 0

1st:

always "g" for GRF

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2nd:

media type, t (SP Adapter), f (FDDI), h (HIPPI), e (100Base-T), etc.

 

 

 

 

 

 

 

 

 

 

3rd:

chassis number, always "0" (zero)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

4th:

slot number in hex

 

 

 

 

 

 

 

 

 

 

 

 

 

 

5th:

logical interface number in hex, always "0" (zero)
