Rules for client identifier specification

Observe the following rules for client identifier specification:

• When the Client Identifier is a single entity on a mapping statement rather than part of a group, no wildcarding is allowed.
• A group name must be defined with the appropriate statement before it can be specified on a MAPPING statement. Otherwise, the name is assumed to be a link or interface name.
• User ID and destination IP address require the clid_type keyword to correctly identify the Client Identifier. If clid_type is not used, a user ID Client Identifier is assumed to be a link or interface name and a destination IP address Client Identifier is assumed to be the traditional client (source) IP address.
• Client Identifiers of a particular type, such as IP address or host name, can be defined within only one group of that type. If the Client Identifier is defined in more than one group, a debug warning message is issued showing the Client Identifier that is ignored and the name of the owning group. No error is issued if a Client Identifier is listed twice in the same group.
