To specify dynamic asynchronous addressing, use theÂ async dynamic address command in interface configuration mode. To disable dynamic addressing, use theÂ no form of this command.
async dynamic address
noÂ async dynamic address
This command has no arguments or keywords.
Dynamic addressing is disabled.
|10.0||This command was introduced.|
You can control whether addressing is dynamic (the user specifies the address at the EXEC level when making the connection) or whether default addressing is used (the address is forced by the system). If you specify dynamic addressing, the router must be in interactive mode and the user will enter the address at the EXEC level.
It is common to configure an asynchronous interface to have a default address and to allow dynamic addressing. With this configuration, the choice between the default address or dynamic addressing is made by users when they enter theÂ slip orÂ ppp EXEC command. If the user enters an address, it is used, and if the user enters theÂ default keyword, the default address is used.
The following example shows dynamic addressing assigned to asynchronous interfaceÂ six.
interface ethernet 0
Â ip address 10.0.0.1 255.0.0.0
interface async 6
Â async dynamic address
|peer default ip address||Specifies an IP address, an address from a specific IP address pool, or an address from the DHCP mechanism to be returned to a remote peer connecting to this interface.|
