IP Address
Enter an IP address to use for the IDS Sensor interface. Cisco SDM will do the
following:
•Create a loopback interface. The number 255 is used if available, if not,
another number will be used. This loopback interface will be listed in the
Interfaces and Connections window.
•Configure the loopback interface with the IP address you enter.
•Configure the IDS network module IP unnumbered to the loopback interface.
•If the IDS network module has already been configured IP unnumbered to an
existing loopback interface, but the interface does not have a valid IP address,
the loopback interface is given the IP address you enter in this window.
IP Address Determination
Cisco SDM displays this window when it needs to determine the IP address of a
network module that you are attempting to manage. This is typically the IP
address of the module’s external Ethernet interface. Cisco SDM can use the
address it used the last time the management application was run, it can attempt
to discover the IP address, or it can accept an address that you provide in this
window.
Select a method, and click OK. If the method you choose fails, you can select
another method.
Use Cisco SDM last known IP Address
Click to have Cisco SDM use the IP address that it used the last time that the
management application for this network module was run. If the IP address of
module has not been changed since the management application was last run, and
you do not want Cisco SDM to attempt discovery of the address, use this option.
Let Cisco SDM discover IP address
Click to have Cisco SDM attempt to discover the network module’s IP address.
You can use this option if you do not know the IP address, and you are not sure
that the last address Cisco SDM used to contact the network module is still
correct.
