SNMP Version 1 and Version 2c

SNMP Version 1 (SNMPv1) and SNMP Version 2c (SNMPv2c) use a community string match for user
authentication. Community strings provided a weak form of access control in earlier versions of SNMP.
SNMPv3 provides much improved access control using strong authentication and should be preferred
over SNMPv1 and SNMPv2c wherever it is supported.

SNMP Version 3

SNMP Version 3 (SNMPv3) is an interoperable standards-based protocol for network management.
SNMPv3 provides secure access to devices by a combination of authenticating and encrypting frames
over the network. The security features provided in SNMPv3 are:
•
•
•
SNMPv3 provides for both security models and security levels. A security model is an authentication
strategy that is set up for a user and the role in which the user resides. A security level is the permitted
level of security within a security model. A combination of a security model and a security level
determines which security mechanism is employed when handling an SNMP packet.

Assigning SNMP Switch Contact and Location Information

You can assign the switch contact information, which is limited to 32 characters (without spaces) and
the switch location.
To configure contact and location information, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# snmp-server contact NewUser
switch(config)# no snmp-server contact NewUser
Step 3
switch(config)# snmp-server location SanJose
switch(config)# no snmp-server location SanJose
To configure contact and location information, follow these steps:
Command
