Common Conﬁguration Mistakes

The following list describes some common conﬁguration errors that may

result in failure during veriﬁcation. The errors are grouped by the

conﬁguration ﬁle that contains them.

See the “OTS and Related Parameters” chapter in the OSI Transport

Services manual for detailed information about all the parameters.

ots_dests Common Mistakes

• Mistyped dest_net_address or the dest_phys_address, will

cause a fail in your attempt to connect.

• Destination entries must be made in order for loopback to work over

both CONS and CLNS/X.25. Be sure to include any X.25 subaddress

when specifying the physical address.

• Destination entries must be made in order for loopback to work over

CLNS/ LAN when CLNP Subset 0 is used. In other cases, destination

entries for LAN should be avoided.

• Specifying the incorrect outgoing subnetwork for a destination, will

cause a fail to connect.

• When specifying reverse charging for X.25, the remote must be

conﬁgured to accept it. Otherwise, it will reject your connection.

ots_subnets Common Mistakes

• Mistyping your local address will cause the remote systems to be

unsuccessful in connecting with you.

• Incorrect CLNP subset for LAN. This can prevent interoperability

with other systems on the LAN. See the parameter

snet_clnp_subset.

• LAN-based networks with a large number of nodes (over 200), should

have the parameter snet_max_es_entries increased. Not doing so

can result in failure to establish connections with other systems.
