the
Shared

Workspace
3.html

As the administrator, you are responsible for building and maintaining the workspace. The workspace is a virtual work
environment that NetBrain uses to emulate your network. Most of workspace data is maintained in
Gateway

and shared by all
Workstations.


The workspace data in the
Gateway

Server includes the device configurations, the network topology (L3 and L2 topology), the
credentials to access the live network, the public device group and the data retrieved from the live network (live data).

All these

data
can be

managed by the Workstatio
n Administrator user interface and some of these data can be managed in Web Interface of
Gateway Server.

Step

Operation

Description

Note



Live Network Setting

Define the credentials to access the live
network. Used to discover network and tune
live access.

If you do not have the configuration files,

you
can go to step 2 and then step 4 to discover
network devices. The configuration files of
discovered devices are automatically imported
to the system.


Network Discovery

Discover the network devices.
The discovered
devices and configurations are automatically
added into the workspace
.

It is recommended that you run discovery to
uncover and populate network devices into the
workspace. Alternately you can
import
configuration files and run tune live access to
populate network devices into the workspace.


Import Configurations

Import network device configuration files. L3
topology is created from the configurations
.



Tune Live Access

Check the
reach
-
ability of a device and fill in
the credentials for each device.


Alternately you

manually define the
credentials for an individual device and a
device group. However Tune Live Access is
more efficient for a large network.


Benchmark

Setup a sched
ule to benchmark the network.


The data retrieved from Benchmark are used
to update the workspace and build L3/L2
topology. The data is also used for network

analysis such as historical path, configuration
and routing comparison.

Build L3 and L2

topology.

You can select
automatically build topologies after each
benchmarked task or manually build them.

You

can
select

for LAN
segments as well as the whole workspace.


Fix up Network

topology and fix up the network data
such as Route Table and NAT table

Live Network Setting

3.1.html

In order for NetBrain Workstation and Network Server to access the live

network, you must define the credentials to access the
network devices. You c
an define the credentials for each device or a device group. NetBrain provides an efficient and better way:
enter all possible credentials of your network and then run Tune Live Access to have the system automatically fill in credent
ials for
you.

Note:



If both the Network Server and
Workstation can access your
network directly, then you do NOT
need set a Jumpbox. Otherwise
y
ou do need set a Jumpbox so that
the Network server or Workstation
can access the live network.



Network Server must be able to
access the network devices via
telnet/SSH or SNMP. If an ACL is
configured for SNMP RO string,
then network server IP address
mus
t be allowed in that ACL.

After network devices have been discovered by seed router, you can select scanning the IP subnets. During the discovery proce
ss,
the system parses live data such as configuration files and routing tables to create a set of destination subnets and directl
y
connected subnets. You can choose to scan all destination subnets or just directly connected subnets. This scan process may h
elp
discover more devices, however, be aware that the scan process can be time consuming. To select scanning subnet options, cli
ck

Options

button in
Live Network Discovery

window and then

tag.


You can create a discovery report after discovery process is done. Click the

Report
button (
) from the
Workspace

tab. The
discovery results are summarized in Discovery
report.

Import Configuration Files

3.3.html

After a network device is discovered, its configuration file is automatically imported into the workspace. Also you can impor
t the
external configuration files into the Workspace.
The imported configurations are used to

build the
network model

and automatically
uploaded to the Gateway Server.

3.3.2
Inside NetBrain

3.3.2.html




After a configuration file is
imported into the workspace, a
virtual device is added into the
workspace as well as its L3
connection. In the next step, you
will add the credentials (device
settings) to access the live
network such as
username/password (see

the next
step) and so relate the virtual
device with the live device. The
configuration file retrieved from
the live device via Benchmark
(see step 5) is used to update the
virtual model.






Note

NetBrain supports
configuration files of Cisco IOS
router, IOS switch, CatOS switch, Pix/ASA firewall, Junos router, 3COM
router/switch
.
A complete list of vendors and hardware models supported can be found
here
. Configuration files need to be of
original text format.

If a vendor or device type is not sup
ported, you can manually add a device into the system. See 3.1 for detail.

s.

You can manually edit the
device setting of a device,


1.

Right click a device from Workspace Space
and select

menu.

2.

Enter the credential directly. Or you can
click the

ton and select one from the
live network setting you just defined.

3.

You can apply these setting to all devices or
a device group. To do so, select the settings
and device groups and click the

button.






More efficiently use
Tune Live Access

to have the system automatically fill in device settings for all devices.
While tuning live
access, the system polls
live devices
using the credentials defined in live network settings. If the system reaches a device
successfully, it will fill in the corr
esponding device settings
.
The results are saved in Gateway Server.


If the
system fails to reach a device via a method, first click the entry of this device in
Tune Live Access

window and view the log
for any clue. If the system can ping the device succe
ssfully but cannot telnet/SSH to the device or reach the device via SNMP, then
quite possibly some live network settings are missing. Refer to step 2.2 to add live network settings. Click

Route tables can be used to calculate the traffic path.



Configurations are used to update L3 topology.



ARP/MAC/CDP tables are used to discover L2 topology.



Route tables and route tables are used to verify what are changed in network design.

devices in following ways:

1.

Import configurations.
See 2.3 for detail.

2.

Discover the network
devices. See 2.2 for
detail.

3.

If device configuration
fails to be retrieved or
the type of device is not

manually add this
device.


1.

Click

,
and

select
Add Generic Device
and then select add
a type of device, such as Add Router.




2.

Fill in device name, management IP address and SNMP RO
string.

3.

Click
SNMP Get

button to fetch interface info. If it fails, you
need manually add L3 and L2 interface information by clicking
Add

button.



Delete a device



Device is removed from the
network



At Workspace Pane (click
View >> Workspace Pane

if it is not
visible), right click the device and select
Remove from Workspace
.


Alternatively at Server Web interface, go to
Worksapce >> Device

having the same IP
address
.

check the
interface you want in the workspace. The other interfaces having the
same IP address are discarded.



Connect
Unnumbered
Interfaces


NetBrain Workstation
creates a list
of the IP
unnumbered interfaces
while building the
network model from the
configuration files. By
default, the IP
unnumbered
