IBM 9077 manual Configuration of SP Switch ATM OC-12c SP Switch

Table 25 shows the IP addresses used in our configuration.

Table 25. Configuration of SP Switch - ATM OC-12c - SP Switch

Adapter	IP Address
SP Switch Router Adapter card 1	192.168.13.4
SP Switch Router ATM media card	10.20.30.2
(port 00) in GRF 400
SP Switch Router ATM media card	10.20.30.1
(port 00) in GRF 1600
SP Switch Router Adapter card 2	192.168.14.4

To successfully run this configuration, on every SP Switch Router a route to the distant SP Switch network has to be set. On the nodes of SP2 and SP21, respectively, routes to the nodes of the distant SP have to be set.

The media card adapters on the GRF routers should already be up and running (according to Section 3.7, “Step-by-Step Media Card Configuration” on page 86 and Section 4.3, “ATM OC-12c Configuration” on page 119). The important settings are repeated here, nevertheless, to be on the safe side:

• On the GRF 1600 (ATM card in slot 2, SP Switch card in slot 3):

1.The file /etc/gratm.conf needs the configuration statements for the port used:

Traffic_Shape name=bigg_speed_high_quality \ peak=622000 sustain=622000 burst=2048 qos=high

Interface ga020 traffic_shape=bigg_speed_high_quality

PVC ga020 0/132 proto=ip traffic_shape=bigg_speed_high_quality

2. The file /etc/grifconfig.conf has the following entries:

gt030	192.168.14.4	255.255.255.0	-	mtu 65520
ga020	10.20.30.1	255.255.255.0	-	mtu 9180

3.The file /etc/grroute.conf has the following line:

192.168.13.0 255.255.255.0 10.20.30.2

This sets the correct route to the other SP Switch network over the ATM OC-12c interface automatically; of course, this route could also be set manually every time the GRF is rebooted.

4.The SP Switch Router Adapter card is connected to the SP Switch and configured, too. Check with SDRGetObjects switch_responds on the CWS and use Eunfence if needed.

•On the GRF 400 (ATM card in slot 1, SP Switch card in slot 3):
