SmartSwitch ATM Switch Reference Manual 2-159

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.

Note The following applies to SmartSwitch 6500 only: 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.
