• LAN Emulation (see Chapter 4, “Conﬁguring LAN Emulation

Interfaces,” on page 37).

Once you have conﬁgured the ATM adapter and conﬁgured at least one

network interface (Classical IP or LAN Emulation), the ATM adapter is

ready to transmit and receive data using Switched Virtual Connections

(SVCs).

Until otherwise conﬁgured, the ATMadapter initially uses a default SVC

trafﬁc proﬁle using Unspeciﬁed Bit Rate (UBR) with a Peak Rate of

either 155 Mbits/s or 622 Mbits/s depending on your ATM adapter. This

default SVC conﬁguration is used for SVCs opened towards unspeciﬁed

destinations. You can modify this default SVC trafﬁc proﬁle as required,

and also create custom SVC trafﬁc proﬁles, which are used for SVCs

toward speciﬁc destinations. For more details about SVCs, see Chapter 5,

“Conﬁguring SVCs and PVCs,” on page 61.

If you wish to conﬁgure PVCs, then you must conﬁgure a Classical IP

interface, because PVCs are supported only on Classical IP over ATM

(see Chapter 3, “Conﬁguring a Classical IP over ATM Interface over an

ATM Interface,” on page 23). For details about conﬁguring PVCs, see

Chapter 5, “Conﬁguring SVCs and PVCs,” on page 61.

NOTE If you change the ATM adapter conﬁguration in your system by adding,

removing, or moving an ATM adapter within the same system, the

correspondence between the hardware paths and the

card_instance_number

s of those adapters might change. So, you must

reconﬁgure the IP interface for any adapters whose conﬁguration has

changed. Patch PHCO_17633 is available to solve this problem. Contact

your HP representative for installation details.
