COS name. Each COS mapping table may have one of these default COS mapping
entries. You can never code a “*” as the native COS name.
High-Performance Routing
See Table 2 on page 25 for a list of ports that support HPR.
See “Configuration Requirements for APPN” on page 26 for information about
configuring the protocols that support APPN and HPR routing over direct DLCs on
the router. In the case of HPR parameters such as retry and path switch timers, the
configuration is done at the node level and is not specified on individual adapters.
DLUR
See Table 2 on page 25 for a list of ports that support DLUR.
Configuring Focal Points
Focal points can be explicit or implicit. Explicit focal points are configured at the
focal point itself. No configuration at the router is required.
Implicit focal points on the other hand are configured at the router. You configure
them with the command add focal_point. Add the primary implicit focal point first. If
you add another focal point, it is known as the first backup implicit focal point. If you
add yet another, it is known as the second backup implicit focal point. Up to eight
backup implicit focal points may be added for a total of 9.
To delete a focal point use the command delete focal_point. You will be prompted
for the name of the focal point to delete. When the name is deleted, the remaining
focal points retain their relative position with each other. Subsequent focal points
will be added at the end of the list.
There is no way to insert a focal point in the middle of the list. You must delete
them one at a time and then re-enter the entire list.
Configuring Held Alert Queue Size
To configure the size of the held alert queue enter the command set management
and answer the
Held Alert Queue Size
question. The queue defaults to a size of
10 alerts, and valid values are from 0 through 255 alerts.
As you increase the size of the held alert queue, additional memory is needed. If
you set it to a high value, you may want to adjust the ″Maximum Shared Memory″
value. See“APPN Node Tuning” on page 38 for additional information.
Defining Transmission Group (TG) Characteristics
When you configure APPN on the router, you can specify the Transmission Group
(TG) characteristics for the link station that defines a connection between the router
network node and an adjacent node. These characteristics, such as the security of
a link or its effective capacity, are used by APPN when calculating an optimum or
least-weight route between nodes in the APPN network.
