Basic Sensor Setup

You can perform basic sensor setup using the setup command, and then finish setting up the sensor using

the CLI, the IDM, or the IME.

You can perform basic sensor setup using the setup command, and then finish setting up the sensor using

the CLI, IDM, or IME. To perform basic sensor setup using the setup command, follow these steps:

Step 1 Log in to the sensor using an account with administrator privileges.

Note Both the default username and password are cisco.

Step 2 The first time you log in to the sensor you are prompted to change the default password. Passwords must

be at least eight characters long and be strong, that is, not be a dictionary word. After you change the

password, basic setup begins.

Step 3 Enter the setup command. The System Configuration Dialog is displayed.

Step 4 Specify the hostname. The hostname is a case-sensitive character string up to 64 characters. Numbers,

“_” and “-” are valid, but spaces are not acceptable. The default is sensor.

Step 5 Specify the IP interface. The IP interface is in the form of IP Address/Netmask,Gateway:

X.X.X.X/nn,Y.Y.Y.Y, where X.X.X.X specifies the sensor IP address as a 32-bit address written as 4 octets

separated by periods, nn specifies the number of bits in the netmask, and Y.Y.Y.Y specifies the default

gateway as a 32-bit address written as 4 octets separated by periods.

Step 6 Enter yes to modify the network access list:

a. If you want to delete an entry, enter the number of the entry and press Enter, or press Enter to get

to the Permit line.

b. Enter the IP address and netmask of the network you want to add to the access list.

Note For example, 10.0.0.0/8 permits all IP addresses on the 10.0.0.0 network

(10.0.0.0-10.255.255.255) and 10.1.1.0/24 permits only the IP addresses on the 10.1.1.0

subnet (10.1.1.0-10.1.1.255). If you want to permit access to a single IP address than the

entire network, use a 32-bit netmask. For example, 10.1.1.1/32 permits just the 10.1.1.1

address.

c. Repeat Step b until you have added all networks that you want to add to the access list, and then

press Enter at a blank permit line to go to the next step.
