An interface group provides a way to group sensing interfaces into one logical
virtual sensor. Only one interface group, 0, is supported. Depending on the
configuration of your sensor, you may need to assign the sensing interface to
interface group 0 and enable the interface.
Review the following guidelines:
If you purchased a new sensor that shipped with Cisco IDS version 4.1:
•
The sensor detects the available sensing (monitoring) interfaces during
–
the bootup process and adds those interfaces to interface group 0.
Note If the XL card is present, only the XL interfaces are added to
interface group 0. If the XL card is not present, all Ethernet
100/1000 interfaces (except the command and control interface)
are added to interface group 0.
– By default, all interfaces the sensor detects and adds to interface group 0
are disabled. You need to use the IDS CLI or other IDS manager to enable
the appropriate interfaces.
Note When you enable an interface the change takes effect
immediately. The sensor does not need to reboot.
If you upgrade an existing sensor to Cisco IDS version 4.1:
•
– The sensor detects the available interfaces during startup but does not
modify the existing interface group 0.
– You must use the IDS CLI or other IDS manager to add the unassigned
interfaces to interface group 0.
If you add or remove interfaces of different types (such as adding
Note
an XL interface and removing an Ethernet 100/1000 interface)
the sensor reboots.
