The media card adapters on the GRF routers should already be up and running (according to Section 3.7,
On the GRF 1600 (HIPPI card is in slot 8, SP Switch card is in slot 3) check for the following:
1. The file /etc/grifconfig.conf has the following entries:
gh080 | 10.50.1.1 | 255.255.255.0 | - | mtu | 65280 |
gt030 | 192.168.14.4 | 255.255.255.0 | - | mtu | 65520 |
2.The file /etc/grlamap.conf has the following entry (note that ’0x40’ is a hexadecimal value equivalent to 64 decimal):
* | 0xfc0 0x40 | # default mapping of IP for all portcards |
3. The file /etc/grarp.conf has the following entry (I-field):
gh080 | 10.50.1.2 | 0x03666fc0 |
4.The file /etc/grroute.conf has the following line:
192.168.13.0 255.255.255.0 10.50.1.2
This sets the correct route to the other SP Switch network over the HIPPI interface automatically; of course, this route can also be set manually every time the GRF is rebooted.
5.The SP Switch Router Adapter card is connected to the SP Switch and configured. Check with SDRGetObjects switch_responds on the CWS and use Eunfence if needed.
On the GRF 400 (HIPPI card is in slot 0, SP Switch card is in slot 1):
1. The file /etc/grifconfig.conf has the following entries:
gh000 | 10.50.1.2 | 255.255.255.0 | - | mtu | 65280 |
gt010 | 192.168.13.4 | 255.255.255.0 | - | mtu | 65520 |
2. The file /etc/grlamap.conf has the following entry:
* | 0xfc0 0x40 | # default mapping of IP for all portcards |
3. The file /etc/grarp.conf has the following entry
gh000 | 10.50.1.1 | 0x03555fc0 |
4.The file /etc/grroute.conf has the following line:
192.168.14.0 255.255.255.0 10.50.1.1
This sets the correct route to the other SP Switch network over the ATM interface automatically; of course, this route could also be set manually every time the GRF is rebooted.
