Transport channel name

Name of the UDP inbound transport channel.

The name field cannot contain the following characters: # \ / , : ; " * ? < > | = + & % '

This name must be unique across all channels in a WAS environment. For example, a UDP transport channel and a TCP transport channel cannot have the same name if they reside within the same system.

Information Value
Default UDP_(n) where (n) represents the number of instances of this channel in the system


Address exclude list

Specifies the IP addresses that are not allowed to make inbound connections. Use a comma to separate the IPv4 and/or IPv6 addresses to which to deny access on inbound UDP connection requests.

The address include list and host name include list are processed before the address exclude list and the host name exclude list. If all four lists are defined:

Information Value
Data type String
Range Valid IPv4 and IPv6 addresses with a wildcard character (*), an asterisk. All four elements of an IPv4 address must be represented by a number or a wildcard character. All eight numeric values of an IPv6 address must be represented by a number or the wildcard character (*).
Example The following examples are valid IPv4 addresses that can be included in an Address exclude list:
*.1.255.0
254.*.*.9
1.*.*.*
All eight numeric values of an IPv6 address must be represented by a number or the wildcard character (*), an asterisk. No shortened version of the IPv6 address should be used. Even though a shortened version is processed with no error given, it does not function correctly in this list. Each numeric entry should be a 1- 4 digit hexadecimal number. The following examples are valid IPv6 addresses that can be included in an Address exclude list:
0:*:*:0:007F:0:0001:0001
F:FF:FFF:FFFF:1:01:001:0001
1234:*:4321:*:9F9f:*:*:0000
