Cisco Intrusion Prevention System CLI Sensor Configuration Guide for IPS 7.1

Chapter 5 Configuring Interfaces
Configuring Inline Interface Mode
• no—Removes an entry or selection setting.
• admin-state {enabled | disabled}—Specifies the administrative link state of the interface, whether
the interface is enabled or disabled.
Note On all backplane sensing interfaces on all modules, admin-state is set to enabled and is
protected (you cannot change the setting). The admin-state has no effect (and is protected)
on the command and control interface. It only affects sensing interfaces. The command and
control interface does not need to be enabled because it cannot be monitored.
Creating Inline Interface Pairs
To create inline interface pairs, follow these steps:
Step 1 Log in to the CLI using an account with administrator privileges.
Step 2 Enter interface submode.
sensor# configure terminal
sensor(config)# service interface
sensor(config-int)#
Step 3 Verify that the subinterface mode is “none” for both of the physical interfaces you are pairing in the
inline interface.
sensor(config-int)# show settings
physical-interfaces (min: 0, max: 999999999, current: 2)

Step 4 Name the inline pair.
sensor(config-int)# inline-interfaces PAIR1
Step 5 Display the available interfaces.
sensor(config-int)# interface1 ?
GigabitEthernet0/0 GigabitEthernet0/0 physical interface.
GigabitEthernet0/1 GigabitEthernet0/1 physical interface.
GigabitEthernet0/2 GigabitEthernet0/2 physical interface.
GigabitEthernet0/3 GigabitEthernet0/3 physical interface.
Management0/0 Management0/0 physical interface.
