You can begin communicating with the agent once your user name is created, your roles are set up by your administrator, and you are added to the roles. Each access can be enabled or disabled within each group. Each group is defined with three accesses: read access, write access, and notification access. Each group in SNMP is similar to a role through the CLI. SNMP access rights are organized by groups. Note Because group is a standard SNMP term used industry-wide, we refer to role(s) as group(s) in this SNMP section. User-role mapping changes are synchronized in SNMP and the CLI.Deleting a user using either command results in the user being deleted for both SNMP and the CLI.

The password specified in the username command is synchronized as the auth and priv passphrases for the SNMP user.The auth passphrase specified in the snmp-server user command is synchronized as the password for the CLI user.To create an SNMP or CLI user, use either the username or snmp-server user commands. SNMP uses the group names to apply the access/role policy that is locally available in the switch.Īny configuration changes made to the user group, role, or password results in database synchronization for both SNMP and AAA.
Additionally, the AAA server is also used to store user group names. Once user authentication is verified, the SNMP PDUs are processed further. This centralized user management allows the SNMP agent running on the Cisco MDS switch to leverage the user authentication service of the AAA server. SNMPv3 user management can be centralized at the AAA server level. While SNMP and the CLI have common role management and share the same credentials and access privileges, the local user database was not synchronized in earlier releases.

The Cisco SAN-OS software implements RFC 3414 and RFC 3415, including user-based security model (USM) and role-based access control. Switch(config)# no snmp-server location SanJose Switch(config)# snmp-server location SanJose Switch(config)# no snmp-server contact NewUser Switch(config)# snmp-server contact NewUser To configure contact and location information, follow these steps: You can assign the switch contact information, which is limited to 32 characters (without spaces) and the switch location. A combination of a security model and a security level determines which security mechanism is employed when handling an SNMP packet. A security level is the permitted level of security within a security model. A security model is an authentication strategy that is set up for a user and the role in which the user resides. SNMPv3 provides for both security models and security levels. Encryption-Scrambles the packet contents to prevent it from being seen by unauthorized sources.Authentication-Determines the message is from a valid source.Message integrity-Ensures that a packet has not been tampered with in-transit.The security features provided in SNMPv3 are: SNMPv3 provides secure access to devices by a combination of authenticating and encrypting frames over the network. SNMP Version 3 (SNMPv3) is an interoperable standards-based protocol for network management.
SNMPv3 provides much improved access control using strong authentication and should be preferred over SNMPv1 and SNMPv2c wherever it is supported. Community strings provided a weak form of access control in earlier versions of SNMP. SNMP Version 1 (SNMPv1) and SNMP Version 2c (SNMPv2c) use a community string match for user authentication.
