Network Directory Data

Fields

Transport services

These three fields describe the transport services that should be configured in each path.

TCP

TCP must be Y (yes) for all nodes. The default is Y.

Checksum for TCP

The checksum setting indicates whether checksumming is optional (N) or required (Y) for TCP. If this field is set to N, then the use of checksums is not requested when communicating with this node. If this field is set to Y then checksums are used when communicating with this node. Checksumming is required for communication to non-HP systems. The default is N.

PXP

PXP must be Y (yes) for all nodes. The default is Y.

Note that the selection of transport services here must match the settings in the remote node's configuration file. If the checksum enabled field in the path NETXPORT.GPROT.TCP of this node is set to Y, then TCP checksum field in the network directory should also be set to Y.

IP Address

One IP address should be entered for each network interface configured on the remote node that is directly reachable from this node. Each address must match an IP address configured in the remote node's configuration file. The path of the screen in the configuration file that contains IP addresses is NETXPORT.NI.NIname.PROTOCOL.IP.

Type

A number indicating the type of path to configure is shown in Table 13-1 "Path Type Configuration":

1

Select this path type when the NI type is ROUTER (point-to-point); or when the NI type is LAN and the destination node supports probe or ARP; or when the NI type is TOKEN or FDDI and the destination node supports ARP.

2

Select this path type when the NI type is LAN, the destination node does not support probe, and 802.3 framing is used.

3

Select this path type when the NI type is X25.

4

Select this path type when the NI type is LAN, the destination node does not support ARP, and Ethernet framing is to be used.

5

Select this path type when the NI type is TOKEN and the destination node does not support ARP.

6

Select this path type when the NI type is FDDI and the destination node does not support ARP.

Table 13-1 Path Type Configuration

NI Type	Framing	Protocols Supported by Remote Node	Type
Point-to-Point (Router)	N/A	N/A	1
LAN, VG100LAN, BT100	802.3 and Ethernet	Either Probe or ARP	1
		Neither Probe nor ARP	4
	802.3 only	Not Probe	2
	Ethernet only	Not ARP	4
X.25	N/A	N/A	3
Token Ring	N/A	ARP	1
	N/A	Not ARP	5
FDDI	N/A	ARP	1
	N/A	Not ARP	6

Additional address

A lower-level address, which depends on the type.

Type 1 does not contain lower-level addressing information. You can leave the field blank, or enter the keyword NONE.

Types 2, 4, 5 and 6 require the destination node's station address, which is a string of six hexadecimal bytes, separated by dashes (XX-XX-XX-XX-XX-XX).

Type 3 requires an X.25 address key, which is an ASCII string of as many as eight characters. Each NETXPORT.NI.NIname.X25.SVCPATH screen may contain up to 2048 X.25 address keys. Each NETPORT.NI.NIname.X25.PVCPATH screen may contain up to 128 X.25 address keys. No address key may be used more than once per system.
