4.5.4 Configuration Files and Profiles
The following are the steps to configure HIPPI cards. For detailed
information, see
GRF Configuration Guide 1.4,
GA22-7366.
1. Identify each logical interface.
Edit the /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
• An MTU, if needed
2. Check the I-field shift in the System profile.
There is one configurable item in the System profile for HIPPI. By default,
the I-field shift is set to 5 bits.
3. Specify HIPPI card parameters in the Card profile (all optional):
• Specify ICMP throttling settings.
• Change run-time binaries.
• Change dump variables.
4. Load profile (optional).
Global executable binaries are set in the load profile in the hw-table field.
These only change when you want to execute new run-time code in every
HIPPI card.
If you want to change the run-time code in one HIPPI card (per physical
interface), make the change in the Card profile, in the load field.
5. Dump profile (optional).
Global dump settings are in the Dump profile. These settings are usually
changed only for debug purposes.
The keep-count field specifies, how many dumps are compressed and
stored at one time for each media card. The default setting is zero (0),
which actually stores two dumps per day (the current dump and the first
dump of the day). Use caution if you change the recommended default.
If you want to change dump settings for one HIPPI card (per physical
interface), make the change in the Card profile, in the dump/config field.
