Viewing or changing the switch prefix
When a M770 ATM Switch with a blank EEROM is powered up, a default prefix is
generated and stored in the EEROM.
The default prefix is 39.00.00.00.00.00.00.xx.xx.xx.xx.xx.xx where x is the MAC
address of the switch.
Note that the first byte of all switch prefixes must start with one of the following:

To display the current switch prefix, use the
address prefix
command.
If you have an ATM network that uses its own block of ATM addresses, you can
make the M770 ATM Switch conform to this scheme by changing the default switch
prefix. Any end-stations directly connected to the M770 ATM Switch will only
obtain their new prefix if they re-register over ILMI.

You must reboot the switch before the above command will take affect. You
must update all the other affected switches’ static routing table entries with the new
switch prefix. If you are using PNNI routing then the affected routing entries will be
updated automatically.

Command:
M15-155s8:/>address prefix
Output:
Current Prefix: 39.00.00.00.00.00.00.00.40.0d.87.00.2c
Command:
M15-155s8:/>address prefix <prefix> [node_id] [pg_id]
Parameters:
<prefix>
The new switch prefix. The prefix must be a 13-byte address and
expressed as 13 two-digit hexadecimal numbers separated by periods.
(39.00.01.02.03.04.05.06.07.08.09.aa.bb) is an example of a switch
prefix address.
The first byte of the switch prefix address must be 39, 45, 47 or 49. For
