Chapter 32 Access Control

Table 90 Management > Access Control > SNMP (continued)

LABEL

DESCRIPTION

Security

Select whether you want to implement authentication and/or encryption

Level

for SNMP communication from this user. Choose:

 

• noauth -to use the username as the password string to send to the

 

SNMP manager. This is equivalent to the Get, Set and Trap

 

Community in SNMP v2c. This is the lowest security level.

 

• auth - to implement an authentication algorithm for SNMP messages

 

sent by this user.

 

• priv - to implement authentication and encryption for SNMP

 

messages sent by this user. This is the highest security level.

 

Note: The settings on the SNMP manager must be set at the same

 

security level or higher than the security level settings on the

 

Switch.

 

 

Authenticati

Select an authentication algorithm. MD5 (Message Digest 5) and SHA

on

(Secure Hash Algorithm) are hash algorithms used to authenticate

 

SNMP data. SHA authentication is generally considered stronger than

 

MD5, but is slower.

 

 

Privacy

Specify the encryption method for SNMP communication from this user.

 

You can choose one of the following:

 

• 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.

 

 

Apply

Click Apply to save your changes to the Switch’s run-time memory. The

 

Switch loses these changes if it is turned off or loses power, so use the

 

Save link on the top navigation panel to save your changes to the non-

 

volatile memory when you are done configuring.

 

 

Cancel

Click Cancel to begin configuring this screen afresh.
