ATM port configuration

Setting the virtual port to its default configuration

If you are attaching an end-station or an edge device that supports ILMI to a
Cajun M770 then you must ensure that the virtual port on the M770 ATM Switch
is using its default configuration. For a list of the default port settings, see Appendix
A Default Settings on a New Cajun M770 ATM Switch. For example, to set vport
8.4.0 to its default settings type:
M15-155s8:/>vport disable 8.4.0
M15-155s8:/>vport reset all 8.4.0
M15-155s8:/>vport enable 8.4.0
This will enable ILMI to automatically configure the virtual port so that it can
communicate with the attached device. For more information on resetting the
parameters on the virtual port, see Resetting parameters on a virtual port in
Managing Virtual Ports.

Connecting to a device, supporting ILMI

If you are attaching an end-station, edge device or another ATM switch which
supports ILMI then the M770 ATM Switch will automatically configure the virtual
port to communicate with the attached device.
Ensure that ILMI is enabled on all devices and the ports have been set to their
default port configuration before attaching the device. ILMI will not alter any
parameters that have been manually configured by the administrator. If a
parameter has been automatically configured for a port, using ILMI, the parameter
will be displayed with an asterisk "*" next to it.

Connecting to a device not supporting ILMI

If you are attaching an end-station, edge device or another ATM switch that doesn't
support ILMI to a Cajun M770, then you must disable ILMI on the M770 ATM
Switch port that connects the two devices.
You should then verify that the following virtual port parameters on the M770
ATM Switch are the same as the parameters on the attached device:
• The port profile must be set to either "network" or "user" (the opposite to the
configuration on the remote device).
• The signalling stack type must be set to either UNI 3.0, UNI 3.1, UNI 4.0,
IISP 3.0, IISP 3.1 or PNNI 1.0 (according to the configuration on the remote
switch).
• Other signalling parameters on the M770 ATM Switch to match the remote
device like VPI and VCI range.
