SNA Node and Link Conﬁguration

Conﬁguring the SNA Node and Link

For an SNA/X.25 SVC:

• “Network Interface Conﬁguration” screen: The Configured

Network Interfaces list must include the NI name speciﬁed for NS

Network Interface Name on the “SNA Node Conﬁguration: X.25

Link Data” screen.

• “X.25 SVC Address Key Paths” screen: The name of the facility set

conﬁgured for the SVC must be found on this screen, even though it

is not actually used in the SNA/X.25 conﬁguration.

— If you follow our recommendation and reserve the facility set for

the SNA/X.25 SVC’s use only, the X.25 Address you specify for

the facility set on this screen must match the address you specify

for Remote’s X.25 Network Address on the “SNA Node

Conﬁguration: X.25 Link Data” screen. Note that this address is

the remote system’s address. Also, the security speciﬁcation in

the “X.25 SVC Address Key Paths” screen must be compatible

with the Call Direction speciﬁed on the “SNA Node

Conﬁguration: X.25 Link Data” screen.

— If you do not reserve the facility set for SNA/X.25’s use, by

associating it with the remote system’s address, you must

conﬁgure it as the POOL facility set. You do this by specifying the

facility set as the default facility set for the POOL X.25 address

key. Also, the security speciﬁcation in the “X.25 SVC Address Key

Paths” screen must be compatible with the Call Direction

speciﬁed on the “SNA Node Conﬁguration: X.25 Link Data”

screen.
