168 IBM 9077 SP Switch Router: Get Connected to the SP Switch
Figure 55. SP Switch - ATM Connection
Table 16 shows the IP addresses used in our configuration.
Table 16. Configuration of SP Switch - ATM Connection
To successfully run this configuration, no routes need to be set on the SP
Switch Router. The F50 and the processor nodes in SP21 require attention,
though. To configure the ATM adapter in the F50, follow these steps:
1. On the F50, check that all the required software for ATM support is
installed. There is no need for ATM LAN Emulation software support,
though. If the ATM adapter is in the "available" state (check with
lsdev -C -c adapter), you are probably fine.
2. To avoid any pitfalls, set the signaling protocol for the ATM adapter to
UNI3.0, as this is the default for the GRF and was probably not changed in
the file /etc/gratm.conf on the GRF. You can check and look for a line
where
Signalling card= is not commented with a #.
It escapes our understanding why we had to bother with this, anyhow, as
we could not set up and use SVC between the F50 and the GRF, because
