Introduction

Thank you for choosing the Cisco Small Business Network Storage System (NSS).

Administering a network can be a difficult job. Finding low-cost ways to simplify
your data-management tasks means that you have more resources to dedicate
elsewhere. The NSS is a Network Attached Storage (NAS) unit that appears as a
native file server for the various clients within your network, including Windows,
Apple Macintosh, UNIX, and Linux platforms. The biggest benefit to your users is
that they can now access data that might be stored across different physical
platforms as simply as if it were on their own computers. The NSS provides a
single repository that is completely dedicated to storage, ensuring the integrity,
reliability, and accessibility of your data for a relatively low cost.

The NSS lets you install up to two physical disk drives. The NSS uses the most
common file-based protocols such as NFS, CIFS, and FTP for file sharing.

1

Benefits

The NSS offers the following main advantages to your business:

• Cross-platform File Sharing: Share files easily and inexpensively across

heterogeneous platforms over a cost-effective Ethernet and IP network.

• Easy Installation and Administration: With a basic understanding of

networking, the NSS is easily configured, managed, and made available to
all of your networked users.

• Data Consolidation: Centralize data to reduce management costs and

maximize your investment in existing hardware. This also means better data
security.

The NSS2000 Series includes the NSS2000 and NSS2050 models. Check
www.cisco.com/go/smallbiz for additional information.

Introduction

Using the Help

Using the Help

1

The NSS (Network Storage System) help file provides information about using the
configuration interface to configure the NSS.

Audience

The information contained in these help pages is intended for use by network
administrators. It assumes a basic understanding of storage-related concepts,
including RAID, filesystems, and networking.

About the NSS Configuration Interface

The NSS configuration interface contains some basic navigation features to help
you as you configure the NSS.

• Manager Menu: The Manager Menu forms the left side of the configuration

interface window. It contains the menu options that represent the major
configuration areas for the NSS. For example, System, Network, Share,
Storage. When you click an option, a sub-menu of related options appears.
Clicking a topic opens the associated topic in the To p i c page in the right
side of the window.

• To p ic Pa g e: When you select a topic from the Manager Menu, the

configuration page for that topic appears in the right side of the window.

Getting Help

There are two buttons on the NSS configuration interface window that you can
click to access help:

• From the Manager Menu click Help to display the full online Administrator

Guide. Use the navigation tools within the help to find information for your
chosen topic.

Cisco Small Business NSS2000 Series Administration Guide 2

Introduction

Using the Help

1

• A context-sensitive help button appears in the upper-right corner of the

topic page. Click it to display help on the specific configuration area. For
example, if the current configuration topic is about the status of your
system, click the Help button for information about the details that appear
on the System Status page.

Refreshing the GUI Pages

Although certain GUI pages automatically refresh at a preselected time interval,
some pages do not refresh until they are reselected. The best way to manually
refresh a GUI page is to reselect it through the options in the Manager Menu on the
left side of the GUI window. For example, to refresh the NTP Configuration page,
from the Manager Menu, click Admin and then click Tim e. We recommend you do
not use the Refresh button on the Web browser toolbar as this can cause data
issues.

Cisco Small Business NSS2000 Series Administration Guide 3

Introduction

Using the Quick Setup Wizards

Using the Quick Setup Wizards

There are three wizards available from the Manager Menu of the configuration
interface:

• Initial Setup: This wizard automatically appears when you log into the

configuration interface for the first time. Although you can access it at any
time from the Manager Menu, if you have saved any configuration settings
before you run the wizard, note that running the wizard will erase any saved
data. For example, if you configure a RAID and then run the wizard, the RAID
will be deleted. This wizard steps you through the basic configuration to
create a RAID, volume, share, user, to set the Home Directory location, set
the time, and so on. (For detailed help on the full set of configuration options,
refer to the online help or to the Administrator’s Guide which you can
download from the Cisco website.)

1

• IP Camera Options: The following wizards let you set up the NSS to store

videos from IP surveillance cameras. The type of wizard you should choose
depends on the way the camera transfers the video clips. Note that you only
need to run the wizard once and then you must configure each the camera
to output the video to the configured share. To run either of the following
wizards, make sure you have created a RAID array, a volume, and any users
that you want to grant access to the surveillance videos. After running this
wizard, you must map a network drive to the share on the PC running the
camera utility and configure the camera utility to save the video to this
mapped network drive

- FTP: Run this wizard if the cameras are set up to transfer motion-

triggered clips. Running the wizard creates a single user and FTP share
for the cameras. The videos are then saved within an FTP folder which
contains a subfolder for each camera.

- CIFS: Run this wizard if the cameras have a Windows utility program that

lets you save the streaming video to a local drive (or in this case, the
NSS) and then view the video from its saved location. The wizard
creates a single user and share for all cameras that are configured to
output to the Windows Utility program. After you run the wizard, you
must map the network drive from the PC that runs the Windows utility
program to the CIFS share.

Introduction

Approved Vendor List for Drives

Approved Vendor List for Drives

If you are purchasing disk drives to install in the NSS, refer to the product support
information offered on the Cisco website (www.cisco.com) for a list of
recommended disk drives.

When you select a disk drive, consider the type of RAID levels required to service
your business needs. For example, if you are creating a RAID (versus a JBOD),
make sure that each of the disks used in the array have the same disk capacity.
The RAID is built using the capacity of the smallest disk in the array.

Cisco Small Business NSS2000 Series Administration Guide 5

Managing the System

The System Status page provides an overview of the current operating condition
of the NSS. For example, you can view system alert messages such as if a disk
drive is failing or has failed, if a volume is approaching its full capacity, and if an
array rebuild is complete. You can also view the current status of any of the
following: storage, shares, backups, network, power, and system details. Status
pages like the System Status page automatically refresh on a regular interval and
are helpful for monitoring the progress of certain processes such as building a
RAID.

problems with the NSS. They require immediate action. For example, if a
disk drive or RAID array is in a failed condition.

• Warning: These types of messages indicate there is a problem with the

NSS that requires eventual action. For example, if the amount of storage
used for a volume is over 90%.

• Notification: These types of messages are simply to advise of changes to

the NSS. For example, the RAID rebuild is complete.

Storage Status

The Storage area displays details about the configured storage on the NSS,
including:

• Drives: The number of physical disk drives installed.

Managing RAID Arrays

Managing RAID Arrays

RAID is an acronym for Redundant Array of Inexpensive Disks. In storage
environments, a RAID array uses multiple physical disk drives to create a single
logical unit from which data can be shared or replicated between the drives. A
RAID array also simplifies the data management as the data appears in one logical
unit. Choosing to store your data using a RAID array gives you the benefit of speed
and performance; storage capacity; decreased downtime costs and increased
availability; fault tolerance; and higher data security.

 RAID.

Choosing a RAID Array Level

RAID (Redundant Array of Inexpensive Disks) is a technology that enables multiple
low-cost hard drives to be used together in a way that increases performance
and/or reliability compared to that of a single drive. The component devices in a
RAID array appear as a single logical storage device. There are various types of

Cisco Small Business NSS2000 Series Administration Guide 42

Configuring your Storage

Choosing a RAID Array Level

RAID, referred to as RAID levels. Some RAID levels increase the performance of
the array, some increase the reliability, and others do a mixture of both. The NSS
supports the following RAID levels: 0 and 1. The NSS also supports JBOD (Just a
Bunch of Disks), which is technically not a RAID level.

The following variables are used in the formulas used to calculate the total
capacity of each RAID level:

Stripe (RAID0): RAID0 stripes the data written to the array across the component
disks. The data is broken into chunks and each chunk is written to a different disk.
Reads and writes to each disk occur in parallel, speeding up the total read and
write performance of the array.

4

• m – capacity of the smallest disk in the array

• n – number of disks in the array

• Minimum Number of Disks: 2

• Total capacity: m * n

• Advantages: Increased read and write performance.

• Disadvantages: Decreased reliability. A failure of any component disk in the

array causes the entire array to fail.

Mirror (RAID1): RAID1 writes the same data to each disk in the array. The disks are
referred to as "mirrors" because each one mirrors the data stored on the others. As
long as one disk in the array is intact, all data can be read back from the array. If a
disk fails in the array and is then replaced, the array must copy the entire contents
of a good disk to the new disk. This process is referred to as “resyncing”. During a
resync, the array continues to be available for reads and writes. When an array
contains a failed disk, it is said to be operating in “degraded” mode. This reflects
the decreased performance and reliability of the array when it is missing disks.

• Minimum Number of Disks: 2

• Total capacity: m

• Advantages: Increased reliability. The array can sustain the loss of all but

one disk without any data loss. Each mirror disk added to the array
increases the reliability (for example, a two-disk RAID1 is half as likely to fail,
a three-disk RAID1 is one-third as likely to fail, and so on). Increased read
performance.

• Disadvantages: Decreased aggregate storage capacity (each mirror disk

does not contribute to the total capacity of the array). Decreased write
performance. I/O intensive when resyncing mirrors.

Cisco Small Business NSS2000 Series Administration Guide 43

Configuring your Storage

Choosing a RAID Array Level

JBOD: JBOD lets you combine multiple disks of mixed capacities into a single
logical storage device. The capacity of the JBOD array is the sum of the total
capacities of the individual component disks (that is, it does not have the limitation
of RAID0 where you lose some capacity when using mixed sized disks). JBOD
offers no performance increase compared to the component disks. It has lower
reliability than the component disks, as the failure of a single disk results, in
general, in the failure of the whole array. Depending on how you create volumes on
the JBOD array, you may be able to recover data when one or more disks in the
JBOD fail. This, however, is not guaranteed.

• Minimum Number of Disks: 1

• Total capacity: sum of capacities of component disks.

• Advantages: Maximal storage capacity, especially when using mixed size

disks.

• Disadvantages: Decreased reliability.

Creating a RAID Array

Creating a RAID Array

After you install the physical disks, you can create the RAID arrays. Before you
create a RAID array, either for the first time, or when you are rebuilding it as a result
of failed disks in the array, it is a good idea to set the Rebuild Priority (see ”Storage

Options” section on page 65) to determine how you want to allocate the system

resources for the rebuild.

4

NOTE: When adding disks to an array, we

recommend you use the same model of disk
with the same capacity. With the exception of a
JBOD, RAIDs are configured to use the
maximum of the smallest disk capacity in the
array for each additional disk in the array. For
example, if you install one, 250 GB disk and one
500 GB disk in a RAID0 array, the total capacity
is only 500 GB.

To create an array:

STEP 1 From the Manager Menu, click Storage  RAID.

The RAID page appears:

Configuring your Storage

Deleting an Array

STEP 2 The available disks appear in the New RAID Device table. Select each disk that

you want to include in the array.

STEP 3 From the RAID Level drop-down menu, click the RAID level of the RAID array you

want to create.

STEP 4 Click Add.

4

The RAID creation can take some time to complete (depending on the size of
the disks and the selected RAID level). You can monitor the progress of the
RAID build from the Storage Status page. When the build is finished, the array
appears in the RAID Arrays table. The disks used in the array are no longer
available for creating additional arrays.

Deleting an Array

You can remove an existing array and release the disks used in the array back into
available storage. Note that deleting an array also deletes any existing data on the
array (including the volumes, shares, and quotas). If you delete an array that
contains the volume that is used as the location of your users’ Home Directories,
note that you must assign a new volume as the Home Directory location.

Migrating a RAID Array to another Storage Device

Migrating a RAID Array to another Storage Device

After you build a RAID array, you can migrate it to a different NSS as required. Note
that you cannot migrate a RAID to or from the NSS4000. You can migrate a RAID
array to or from any of the other NSS models. If you are migrating a RAID array
from the NSS to another network NSS, ensure that you coldplug the RAID array
(versus hotplug it) into the new system as per the following:

STEP 1 Power down the NSS (from which you are removing the RAID array).

STEP 2 Remove each of the disk drives that make up the RAID array to be moved.

STEP 3 Power down the NSS to which you are migrating the RAID array.

STEP 4 Insert each of the disk drives in the RAID array into the new NSS.

4

NOTE: You can install the drives into the new

NSS in any order (that is, you do not need to
install them in the same order or slots that they
were installed in the original NSS).

STEP 5 When all the disk drives are installed, power up the NSS.

STEP 6 If any local users were assigned permissions to shares on the RAID array, you

must either save the configuration from the original RAID array device and then
upload it to the new NSS, or manually reconfigure the users and their share
permissions.

from a device that uses imported storage.

Currently Exported Storage

When you display the Storage Virtualization page, the Currently Exported Storage
table appears. It shows the details for any exported disks or arrays:

• Device: The name of the exported disk or array.

• Size: The size of the exported storage.

• Exported As: The serial number of the exported NSS.

• Imported by: The serial number of the NSS that has imported the storage. If

the exported disk or array has not yet been imported by the master NSS,
"None" appears in this column.

• Action: Click the Unexport button to stop the NSS from exporting the

associated drive or array. This frees up the drive or array for use in local
RAID arrays.

Exporting Storage to your Network

Exporting Storage to your Network

If you have multiple NSS units in your network, you can easily export the storage to
form a large, logical storage unit that can be managed from the master NSS. The
first step in creating virtualized storage is to export the disk(s) or array to the
network. Note that when you export storage, you need to consider how things like
rebooting an NSS might impact users of the virtualized storage. While the logical
storage is controlled from the master NSS, the physical device (including the disk
drives) is still controlled through the slave’s configuration interface and is affected
by the conditions of the physical unit.

CAUTION: After you configure a virtual RAID,
you cannot migrate the disks used for that RAID
to another NSS. You also cannot export storage
from a device that uses imported storage.

To export storage to the network:

STEP 1 Log into the configuration interface for the device from which you are exporting

storage.

The selected disk(s) disappear from the available list of arrays and appear in
the Currently Exported Storage table at the top of the page. Follow the steps to
create a JBOD from virtualized storage to use the exported storage.

Creating Virtualized Storage

4

After you export storage from a slave storage unit, it becomes available to other
storage units in your network. The recommended way to use virtualized storage is
to assign a master storage unit (the master must be an NSS6000 series model).
The designated master unit then becomes the configuration point for all your
storage-related management. Exported storage can be used to create a JBOD,
which can then be used to set up volumes and shares. Keep in mind that although
the storage is managed through the master unit, the physical device that contains
the exported storage is still managed through the applicable slave unit. If you
affect the physical disk drives (e.g., shut down the power to the unit), this affects
any logical storage built using those disk drives.

NOTE: After you configure a virtual RAID, you
cannot migrate the disks used for that RAID to
another NSS. You also cannot export storage
from a device that uses imported storage.

To create a JBOD with exported disks:

STEP 1 Log in to the configuration interface from the master NSS6000 series unit.

enter in this field due to filesystem overhead. The minimum volume size is
32 MB. Volume sizes are rounded down to the nearest 32 MB increment.

NOTE: Once the volume is created, you can
expand the volume but you cannot reduce its
size.

NOTE: You can encrypt the volume only when
the volume is first created. After a volume is
created, you cannot change whether it is
encrypted or unencrypted. File transfer
performance to encrypted volumes is generally
lower than to non-encrypted volumes.

STEP 4 Enter a password in the Password field. The password must be entered to unlock

an encrypted volume when the NSS is started up following a power interruption,
shutdown, or rebooted, or, if the volume was manually locked through the NSS
configuration interface. The password can be any alphanumeric characters (with
the exception of the ";" |", and "&"). It cannot contain any spaces and must be a
minimum of one character (no maximum).

CAUTION: Because you need the password to
decrypt a locked volume, keep a secure
backup of the password to ensure that it is
accessible when required. There is no way to
unlock the volume without the password. (If the
password is forgotten, the only way to unlock
the volume is if a known password was saved
in a configuration file. You can then restore the
configuration, and then use that password to
unlock the volume. See Restoring the
Configuration for help on this.)

• Grow By: Select this option to add the space allocated in the Size field to

the existing space for the volume. For example, if the volume currently has
224 MB of space and you want to add another 224 MB, select "Grow By",
then enter 224 in the Size field, and then set the unit field to MB. Note: The
system rounds up the total space to the nearest 32 MB boundary.

• Resulting Size: Select this option to resize the volume to the space entered

in the Size field. For example, if the volume currently has 224 MB of space
and you want it to have 928 MB, select "Resulting Size" and then enter 928 in
the Size field. Note: The system rounds up the total space to the nearest 32
MB boundary.

STEP 4 Depending on your choice in the previous step, enter the new number in the Size

• Idle Drive Spin Down: Configure the NSS to spin down the disk drives after

a predefined time of inactivity. Select the period of time that the disk drive
must be idle before it is spun down.

• RAID Rebuild Priority: During normal operation, the CPU switches between

tasks to service all active tasks on the system. Creating a RAID array or
rebuilding an existing array can take up a significant amount of the available
percentage of CPU processing power. You can control how the system
prioritizes the rebuild and allocates the system’s resources based on your
system’s current workload and need for responsiveness. To set the RAID
rebuild priority, choose one of the following from the RAID Rebuild Priority
field:

- High: The CPU focuses on the RAID rebuilding process. This setting

allows for the fastest possible RAID rebuild at the expense of other
system tasks. File-sharing throughput is adversely affected during a
RAID rebuild when this setting is chosen.

- Medium: This option gives a balance between the rebuild process and

other system tasks. The rebuild process takes longer than if it was set to
High.

- Low: The CPU focuses on other tasks versus the RAID rebuild process.

This results in a longer rebuild time on a busy system. However, if the
workload on the system is low, the CPU services the rebuild process
well. Note that if you are repairing an array, this option leaves the array
the most vulnerable of all the options as it takes the longest for the
rebuild to complete.

users is imported into the Configured Users list. You can view the entire user list
from the Configured Users page but can only edit or delete locally created users
(not domain users). (The one exception to this is that you can edit the email
address directly from the Configuration Manager.) The naming conventions use
the NetBIOS format with the domain name as a prefix of the username. The
primary group for users set up within the ADS, NTv4 or NIS domain is taken from
the user’s domain profile versus the Primary Group field in the NSS user profile.

NOTE: It is important to set up your User and
Group ID ranges before you join the NSS to an
ADS, NTv4, or NIS domain. After you join the
NSS to a domain, you should not make changes
to the range as this might lead to an ID collision.

hostname is "NASadmin" and the local username is "bob", the user would need to
log in as "NASadmin\bob" in the login dialog.

Deleting a User Profile

You can delete user profiles that were created via the NSS. Note: When you delete

The selected user(s) disappear from the list of available users.

Working with Groups

Groups are an easy way to manage users with the same storage needs and
privileges. A group consists of one or more users. You can add or remove users
from a group at any time. The user’s primary group (the group to which quota
charges for storage usage are applied) is set up in the Primary Group field of the
user’s profile.

5

A group called "nasusers" is automatically created when you first install the NSS.
This group is the default primary group when you create new users.

Creating a Group

Groups let you specify the share access privileges for a set of users. After you
create a group, you can define the group’s access privileges on a per-share basis.
You can add or remove users to and from the group at any time. Note that users are
assigned a primary group within their user profile. When users create a file, the
group ownership is automatically set to their primary group. The storage usage is
charged to their primary group for the purposes of volume quota accounting.
Group membership, other than the primary group, is defined in either the Add
Group or Edit Group page and is used only to control access to shares and files.

NOTE: You cannot grant security privileges to
a group for a CIFS share through ACL.

machine before the change takes effect. This
means that users no longer assigned to a group
maintain full group privileges (i.e., access to
shares) until they log off/log on to their
computer.

To change the group membership:

STEP 1 From the Manager Menu, click Access  Groups.

The Configured Groups page appears.

STEP 2 From the list of configured groups, select the group that you want to change.

Integrating Groups from an Active Directory, NTv4, or NIS
Domain

When the NSS is joined to an Active Directory, NTv4, or NIS domain, domain
groups only appear on the Shares page (they do not appear in the list of
configured groups). Group membership for imported domain groups are read­only. The naming conventions use the NetBIOS format with the domain name as a
prefix of the group name. For example, "DOMAINNAME\GroupName".

NOTE: It is important to set up your User and
Group ID ranges before you join the NSS to an
ADS, NTv4, or NIS domain. After you join the
NSS to a domain, you should not make changes
to the range as this might lead to an ID collision.

Managing Volume Quotas

Managing Volume Quotas

You can set up specific space limits for each user or group who has write access
to a volume. Defining a user or group’s quota means that you can set a space limit
(referred to as a soft quota) that, when reached, sends a warning to the
administrator and initiates a countdown of the defined grace period. The user has
the amount of time in the grace period to reduce the amount of space used to
under the soft quota limit. Users who do not reduce the space in the allotted grace
period, or who reach their hard quota limit, no longer have write access to the
volume until they reduce their usage to under their soft quota limit.

When a user creates, modifies or deletes a file on a volume, note that there is a
small delay before the usage is updated on the Filesystem Quota page. This delay
is due to the caching in the filesystem used to provide high performance.

5

NOTE: Before you create or edit a quota

located on an encrypted volume, make sure the
volume is unlocked. You also need to set up the
Warn For time for each volume from the
Filesystem Quota page. The Warn For time only
affects individual quota that was created after
the Warn For time was set.

Changing the User’s Primary Group

Quotas are charged to the group assigned as the user’s primary group at the time
of file creation. If the user’s primary group changes, files created under the
previous group continue to be charged against that group. Note that if the user’s
primary group changes while the user is connected to the NSS, the previous
primary group continues to be the group charged until the user’s connection is
closed. The new primary group becomes the group charged only after the
connection is re-opened.

NOTE: If the user is created within a domain,
the primary group defined is in the user profile
from the domain, not the Primary Group field in
the NSS user profile.

Creating Volume Quota for a User or Group

You can set up a quota on a volume for each user or group. This quota limits the
user or group to the allocated amount of space within the volume. To give certain
users or groups assigned to a volume full access to the space on the volume, do
not create a quota for that user or group.

NOTE: Before you can create quota on an
encrypted volume, make sure it is unlocked.
You also need to set up the Warn For time for
each volume from the Filesystem Quota page.
The Warn For time only affects individual quota
that was created after the Warn For time was

STEP 4 Select the user or group for which you are creating the quota from the For User/

Group drop-down list.

STEP 5 In the Warning at field, enter the threshold of space that, when exceeded, triggers

a warning that the quota is close to being used up. Select the size unit from the
drop-down menu. When the threshold is exceeded, the grace period set up for the
volume begins. The user has the amount of time set in the grace period to reduce
the amount of space used to under the space set in the Warning at field or they are
not allowed to write further data to the volume. Another way to think about this
field is as a "soft quota".

STEP 6 In the Space Limit field, enter the amount of space that the user or group has

available to use, and then select the size unit from the drop-down menu. Another
way to think about this field is as the "hard quota". If the user reaches the space
limit, the user can no longer write data to the volume until they either reduce the
amount of space used to under the limit by deleting files or have the quota
increased.

Setting up the Grace Period for a Volume Quota

You can set up a limit on the amount of space available to your users or groups.
This limit can be set as a soft quota and hard quota. When the users reach their
"soft quota", a warning is issued and the grace period begins. Users then have the
amount of time set in the grace period to either reduce the amount of spaced used
by deleting files, or have the quota increased. If the amount of space is not
reduced before the grace period expires or the user reaches the hard quota, the
user is automatically denied write access to the volume.

NOTE: Before you create quotas for a user or
group, make sure you set up the Warn For time
for each volume from the Filesystem Quota
page. The Warn For time only affects individual
quota that was created after the Warn For time
was set.

Network Filters Overview

Network Filters Overview

In addition to providing storage for your data, the NSS provides a configurable
firewall to protect that data. Defining network filters lets you specify which
network hosts have access to the NSS via the various supported protocols.

To view the network filters:

STEP 1 From the Manager Menu, click Access  Network.

The Network Filters page appears.

5

STEP 2 You can do any of the following:

• Set the default network policy to control what happens to traffic not

explicitly covered by defined filters. See the ”Defining the Default Network

Policy” section on page 88.

• View or delete the existing filters defined for the NSS from the Active

Network Access Filters table. See the ”Network Filters Overview” section

on page 87.

• Create a new filter based on an IP or MAC address or a range of IP

addresses. See the ”Creating a Network Filter” section on page 89.

Cisco Small Business NSS2000 Series Administration Guide 87

Setting up End-User Access

Defining the Default Network Policy

Defining the Default Network Policy

The default network policy is the overarching policy that defines the gateway for
communication to the NSS. It specifies how traffic that is not covered by defined
filters is handled. The default policy can be defined to either accept or reject such
traffic.

To define the default network policy:

STEP 1 From the Manager Menu, click Access  Network.

The Network Filters page appears.

5

STEP 2 From the Default Network Policy drop-down menu, click one of the following:

• Accept Traffic: Allow the NSS to communicate with all initiating hosts.

Select this option if you have a limited number of systems that you want to
disallow. When you set up your individual filters, select those filters that
"disallow" (i.e., drop or reject) certain types of connections. For example, you
might want to disallow CIFS connections but allow all other types.

• Drop Traffic: Disallow the NSS from communicating with any initiating

systems. Select this option if you have a limited number of systems that you
want to allow to communicate with the NSS. When you set up your filters,

Cisco Small Business NSS2000 Series Administration Guide 88

Setting up End-User Access

Creating a Network Filter

STEP 3 Click Change Policy.

select those filters that "allow" certain types of connections. For example,
you might only want to allow FTP connections.

NOTE: If you set the default policy to Drop
and you want to enable FTP connections, make
sure you set the FTP connection type on the
host to "active". (If you set the connection type
to "passive" you can connect to the NSS but are
not able to list, transfer the data, and so on.)

Creating a Network Filter

The Active Network Access Filters table on the Network Filters page displays
currently defined filters. These filters control if access to the NSS from specified
hosts is granted or denied on a per-protocol basis. Each device in your network is
assigned a fixed 48-bit MAC address and changeable 32-bit IP address. When
you define a filter, it grants or denies access via the specified protocol from the
specified IP/MAC address or range of IP addresses.

NOTE: When you define a new filter, any
existing connections that would normally be
denied by this rule remain in tact. These
connections are denied during the next attempt
to connect to the NSS.

The Network Filters page appears.

STEP 2 From the New Network Access Filter table, type the IP/MAC address to which you

are applying the filter, in the IP/MAC address field. You can also enter addresses
for the following:

• An IP Address Range: Type the range according to the following format:

address-last address

first, followed by a hyphen, and then the last IP address in the range.)

. (Where the first IP address in the range is entered

first

• A Subnet: Enter the subnet to set a filter for all the addresses within the

subnet. The format should appear as shown in the following example:

192.168.1.0/24 (where the digits following the slash represent the number of
bits in the network portion of the IP address).

STEP 3 From the Filter drop-down menu, select the type of filter you want to apply to the

IP/MAC address.

STEP 4 Click Add.

Any connections that apply to the new filter rule are affected by the rule during
the next connection attempt.

• Allow All: This is the default filter. It tells the NSS to accept traffic via all

supported protocols.

• Allow CIFS: Allow CIFS filesharing access.

Cisco Small Business NSS2000 Series Administration Guide 91

NOTE: Rejecting versus Dropping Traffic:
When incoming traffic matches a "reject" filter,
the NSS drops the traffic and then sends a
notice to the initiating system of the denial of
service. When incoming traffic matches a "drop"
filter, the NSS drops the traffic but no notice is
sent to the initiating system
