Chapter 3 Configuring Router and Switch Devices
Generic Router Device
Add and Configure a Generic Router in MARS
To add and configure a generic router device in MARS, follow these steps:
Step 1
Select
Admin > System Setup > Security and Monitor Devices >
Add
.
Step 2
Select
Generic Router version unknown
from the Device Type list.
Step 3
Enter the name of the device in the Device Name
field.
MARS maps this name to the reporting IP address. This name is used in topology maps, queries, and in
the Security and Monitoring Device list. For devices that support the discovery operation, such as routers
and firewalls, MARS renames this field’s value to match the name discovered in the device
configuration, which typically uses the
hostname.domain
format. For devices that cannot be discovered,
such as Windows and Linux hosts and host applications, MARS uses the provided value.
Step 4
(Optional) To enable MARS to discover settings from this device, enter the administrative IP address in
the Access IP field.
To learn more about the access IP address, its role, and dependencies, see
Understanding Access IP,
Reporting IP, and Interface Settings, page 2-8
.
Step 5
Enter the IP address of the interface that publishes syslog messages, SNMP notifications, or both in the
Reporting IP field.
To learn more about the reporting IP address, its role, and dependencies, see
Understanding Access IP,
Reporting IP, and Interface Settings, page 2-8
.
Step 6
If you entered an address in the Access IP field, select
SNMP
from the Access Type
list.
For more information on understanding the access type, see
Selecting the Access Type, page 2-10
.
Step 7
(Optional) To enable MARS to retrieve MIB objects for this reporting device, enter the device’s
read-only community string in the SNMP RO Community field.
Before you can specify the SNMP RO string, you must define an access IP address. MARS uses the
SNMP RO string to read MIBs related to a reporting device’s CPU usage, network usage, and device
anomaly data and to discover device and network settings .
Step 8
To add this device to the MARS database, click
Submit
.
Result
: The submit operation records the changes in the database tables. However, it does not load the
changes into working memory of the MARS Appliance. The activate operation loads submitted changes
into working memory.
Step 9
Click
Activate
.
Result
: MARS begins to sessionize events generated by this device and evaluate those events using the
defined inspection and drop rules. Any events published by the device to MARS before activation can
be queried using the reporting IP address of the device as a match criterion.
