NetPrefix

Use NetPrefix to set or display network ATM address prefixes on a particular port. The 13-byte net prefix is based on

a hierarchical addressing scheme. The default value starts with the first byte set to 39 (DCC address format), followed

by nine pairs of 00s. The net prefix value typically is supplied by the network side of the UNI (user network interface).

See the ATM address structure diagram following.

2p›F You can hot-swap TSMs. Hot-swapping is replacing a module when the chassis is

powered up. If you replace a TSM with another TSM of the same type (same I/O

ports), existing configuration of port parameters is not affected. This includes

parameters set using any of the following attributes: ATMRoute,

CACServiceClassBw, IlmiConfig, NetPrefix, Port, PortConfig, PVC, PVP,

ServiceRegistry, SigTimer, SigStatistics, SSCOPConfig, and SSCOPStatistics. If

you replace a TSM with another TSM of a different type, existing configuration

of port parameters is deleted. The deletion occurs when the new module is plugged

into the chassis backplane.
