DESCRIPTION

 

Server Access

Select the interface(s) through which a computer may access the NWA1121-NI using

 

 

SNMP and to which the IP and MAC filtering rules you specified below are applied.

 

 

Otherwise, select Disable to allow any computer to access the NWA1121-NI through

 

 

any interface using SNMP.

 

 

 

 

Secured Client IP

A secured client is a “trusted” computer that is allowed to communicate with the

 

Address

NWA1121-NI using this service.

 

 

Select All to allow any computer to access the NWA1121-NI using this service.

 

 

Choose Selected to just allow the computer with the IP address that you specify to

 

 

access the NWA1121-NI using this service.

 

 

 

 

Secured Client MAC

Select All to allow any computer to access the NWA1121-NI using this service.

 

Address

Choose Selected to just allow the computer with the MAC address that you specify to

 

 

 

 

access the NWA1121-NI using this service.

 

 

 

 

SNMP Configuration

 

 

 

 

 

Protocol Version

Select the SNMP version for the NWA1121-NI, which you allow the SNMP manager to

 

 

use to access the NWA1121-NI.

 

 

The SNMP version on the NWA1121-NI must match the version on the SNMP manager.

 

 

 

 

Get Community

Enter the Get Community, which is the password for the incoming Get and GetNext

 

 

requests from the management station.

 

 

 

 

Set Community

Enter the Set community, which is the password for incoming Set requests from the

 

 

management station.

 

 

 

 

Trap Community

Type the trap community, which is the password sent with each trap to the SNMP

 

 

manager.

 

 

 

 

Trap Destination

Type the IP address of the station to send your SNMP traps to.

 

 

 

 

SNMPv3 Admin

 

 

Settings

 

 

 

 

 

SNMPv3 Admin

Select the check box to enable the SNMP administrator account for authentication with

 

 

SNMP managers using SNMP v3.

 

 

 

 

User Name

Specify the user name of the SNMP administrator account.

 

 

 

 

Password

Enter the password for SNMP administrator authentication.

 

 

 

 

Confirm Password

Retype the password for confirmation.

 

 

 

 

Access Type

Specify the SNMP administrator’s access rights to MIBs.

 

 

Read/Write - The SNMP administrator has read and write rights, meaning that the

 

 

user can create and edit the MIBs on the NWA1121-NI.

 

 

Read Only - The SNMP administrator has read rights only, meaning the user can collect

 

 

information from the NWA1121-NI.

 

 

 

 

Authentication

Select an authentication algorithm used for SNMP communication with the SNMP

 

Protocol

administrator.

 

 

MD5 (Message Digest 5) and SHA (Secure Hash Algorithm) are hash algorithms used

 

 

to authenticate SNMP data. SHA authentication is generally considered stronger than

 

 

MD5, but is slower.

 

 

 

 

Privacy Protocol

Specify the encryption method used for SNMP communication with the SNMP

 

 

administrator.

 

 

DES - Data Encryption Standard is a widely used (but breakable) method of data

 

 

encryption. It applies a 56-bit key to each 64-bit block of data.

 

 

AES - Advanced Encryption Standard is another method for data encryption that also

 

 

uses a secret key. AES applies a 128-bit key to 128-bit blocks of data.
