This table describes the significant commands shown in the SSM mapping configuration example.
Table 20: SSM Mapping Configuration Example Command Descriptions
DescriptionCommand
Disables IP DNS-based hostname-to-address
translation.
The no ip domain-list command is shown
in the configuration only to demonstrate that

translation does not conflict with configuring
SSM mapping. If this command is enabled,
the Cisco IOS XE software will try to resolve
unknown strings as hostnames.
Note
