SNA Node and Link Conﬁguration

Conﬁguring the SNA Node and Link

• Conﬁgured an address key for the SNA/X.25 PVC in the X.25 System

Access network interface conﬁguration, if you want to reserve the

PVC for only SNA/X.25’s use.

For an SNA/X.25 SVC:

• Conﬁgured a network interface (NI) for the SNA/X.25 SVC in the

X.25 System Access conﬁguration. The value you specify for NS

Network Interface Name on the screen shown in Figure 2-8, “X.25

Link Data Screen,” matches the NI name you conﬁgured.

• Conﬁgured a facility set in the network interface with the same

parameters as the facility set on the host. The HP e3000 facility set

can be conﬁgured for the SNA/X.25’s SVC use only, or for use by any

SVC. We recommend that you conﬁgure the facility for only

SNA/X.25’s use, because that ensures that SNA/X.25 receives only

incoming calls intended for it.

Data Required from the NS Conﬁgurations

Certain items from the X.25 System Access conﬁguration and the DTC

Manager conﬁguration or the DTS conﬁguration must match or be

compatible with items in the SNA/X.25 conﬁguration. Listed below are

the X.25 System Access conﬁguration screens and DTC Manager

conﬁguration or DTS conﬁguration screens that contain those items.

For an SNA/X.25 PVC:

• “DTC Manager DTCX25 Board # Level 3” screen or “DTS DTC X.25

Card Conﬁg — Level 3 &Miscellaneous” screen: The PVC LCI Range

must include the PVC number speciﬁed for PVC Number on the

screen shown in Figure 2-8, “X.25 Link Data Screen.”

• “Network Interface Conﬁguration” screen: The Configured

Network Interfaces list must include the NI name speciﬁed for NS

Network Interface Name on the screen shown in Figure 2-8, “X.25

Link Data Screen.”

• “X.25 PVC Address Key Paths” screen: If you want to reserve an

X.25 address key for the SNA/X.25 PVC’s use only, the PVC Number

must match the PVC Number speciﬁed on the screen shown in Figure

2-8, “X.25 Link Data Screen.”

Figure 2-9, “PVC Conﬁguration Dependencies,” shows the conﬁguration

dependencies for an SNA/X.25 PVC.
