130 IBM 9077 SP Switch Router: Get Connected to the SP Switch
The arguments field is also used to specify ISO when an ISO address is
being added to an interface’s IP address. Specify the MTU value as
mtu xxxx .
Leave the arguments field blank if you are not using it.
The following excerpt from our /etc/grifconf.conf file shows the format of an
entry:
As you can see, we used three interfaces and left out the specification for the
MTU size on the last two, as 4352 is the default for FDDI.
4.4.7 Specify FDDI Card Parameters
The following steps are, as mentioned, optional, and in an SAS environment
without optical bypass you can safely use the defaults.
If there is a need to set ports from SAS to DAS, refer to GRF Configuration
Guide 1.4, GA22-7366, or look at the example in “Configuring SAS versus
DAS” on page 123 for quick help.
4.4.8 Installing Configurations or Changes
In the command line interface (CLI), which is the working environment on the
GRF with the
super> prompt, use the set and write commands to install
configuration parameters onto the media card.
If you apply changes to files in the /etc directory, do not forget to issue
grwrite -v to have these changes written to flash, so that they are still in
effect after a reboot of the GRF.
Additionally, when you enter configuration information or make changes, you
must also reset the media card for the changes to take place. Enter
grreset <slot_number> to do so.
Hint: We found that some changes did not go into effect until the GRF was
rebooted, although the documentation indicated otherwise. So do not hesitate
to
reboot if things seem not to work as they should.
