HOWTO AIX: How to add additional TCP/IP interfaces to an ATM adapter.
I am trying to configure a Turobways 155 ATM adapter in a
RISC System/6000 running AIX V 4.1.4.
I understand that multiple TCP/IP network addresses can be
configured on a single ATM adapter. Unfortunately, I don't
understand how to fill in the SMIT menu. Can you help with
Yes. Here's a look at a sample SMIT menu and some notes on
filling in the data.
Add an ATM Network Interface
Internet Address [188.8.131.52]
Network Mask [255.255.255.0]
Network Interface [at0] \<--- free key field
Connection Type [pvc] \<--- options: svc_c, svc_s, pvc
ATM Server Address [ ] \<--- for svc_c connections only!
Alternate Device [atm0] \<--- ATM adapter name (free key)
Idle Timer 
Activate Interface [yes]
after creating it?
Notice that the network interface value is a free key area. Up
to 64 interfaces (numbered in hex as at0 through at3f) can be
created on a single system. Because it is a free key field,
users may elect to add the interfaces in a chronological or
random order, or they may choose to reserve number ranges for
each adapter. The ability to configure multiple IP addresses of
a single interface type and on a single adapter is unique to the
ATM driver. Each TCP/IP interfaces on a RISC/6000, regardless
of the network type, must be defined for a unique IP subnet. In
our example, a second interface could be defined as 184.108.40.206,
but 220.127.116.11 would be invalid.
Each interface must be configured as either PVC, svc_c (SVC
Client system), or svc_s (for the SVC Server system). The ATM
Address for an SVC Server is required only for SVC Client
systems. Leave this field blank for pvc or svc_s systems.
The "Alternate Device" is the name of the physical adapter.
Currently, two ATM adapter (regardless of speed) are supported
in a single system. Thus, the options are atm0 or atm1.
