Avaya M770 ATM Switch User’s Guide 13
For example, if you are connecting an Avaya M400 Gate Switch LSA+ module
which does not support ILMI, to port 8.4.0 on the M770 ATM Switch, you should
configure port 8.4.0 on the M770 ATM Switch by performing the following steps:
Routing Configuration
PNNI Configuration
When you configure your network you have to decide whether you're going to use
a single peer group (flat) configuration or multiple peer groups (hierarchy)
configuration. In case you have devices that do not support PNNI, please refer to
Section Connecting to another ATM switch which doesn’t support PNNI.
Flat PNNI Configuration
Connecting to another ATM switch which supports PNNI
If you are attaching another ATM switch that supports PNNI ensure that the
following conditions exist:
• All switches should have a different ATM prefix (although the network will
work even if some have the same prefix). To check this in the ATM switch type:
‘address prefix’ (on the Master Agent modules).
• All switches must have a different node_id. By default it will be taken from the
switch address.
• All switches, in the same peer group, must have the same pg_id
• All switches in the same peer group must have the same level.
To check the PNNI and ATM addresses of the switch, type one of the following
commands:
M15-155s8:/> summary info
or
M15-155s8:/> route pnni config show
Note: Changing the PNNI ‘level’ also changes the first byte of the Node ID and the
Peer Group ID.
M15-155s8:/>vport disable 8.4.0
M15-155s8:/>vport disable 8.4.0 ILMI
M15-155s8:/>vport set stacktype 8.4.0 UNI 3.0
