Figure 36. Components of the Ethernet Interface Name
The interface name is used in the /etc/grifconfig.conf file to specify an IP
interface. Interface 7 on the Ethernet card in slot 3, for example, would be
added to this file as:
#name address netmask broad_dest arguments
ge037 xxx.xxx.xxx.xxx 255.255.255.0 - mtu 1500
Note: Interface names are case sensitive. Always use lower case letters
when defining interface names.
4.1.2 Configuration File and Profile Overview
These are the steps to configure Ethernet interfaces:
1. Identify each logical interface
Edit /etc/grifconfig.conf to identify each logical interface by assigning:
• An IP address
• The GRF interface name
• A netmask, as required
• A destination or broadcast address, as required
• A Maximum Transmission Unit (MTU), if needed
2. Specify Ethernet card parameters in the card profile
These are the configurable items in a card profile for an Ethernet media
card (all but the first optional):
• Configure interface mode: autonegotiate, 10 or 100 Base-T, full or half
duplex
• Specify verbose option for messages from the Ethernet card
• Specify ICMP throttling settings
• Specify selective packet discard percentage
