mod Node Prefix

This attribute specifies an NSAP prefix which is distributed to all other Passport nodes within a Topology region and by which this node can be identified. This prefix is used by PORS, PNNI routing, and Data Shunts. PORS calls that use NSAP addressing (for example, CES) will look for the node with the longest NSAP prefix that matches the called party address. The NSAP prefixes that PORS matches against are the nodePrefix and the alternatePorsPrefixes. PNNI forms the default value of the nodeAddressPrefix under the AtmPnni component with this NSAP prefix followed by a unique MAC address. Data Shunts uses the nodePrefix to form an NSAP address that is registered with the Networking API. This NSAP address is used to identify this node when establishing a Data Shunt. The value entered must be 26 characters long. All characters must be hexadecimal with the following restrictions: - the first two characters must be either '39', '45', or '47' - if the first two characters are '45', the 18th character must be an 'f' or an 'F'
