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.

#BROCADE SAN SWITCH ENABLE SNMP SOFTWARE#
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. Assigning SNMP Switch Contact and Location Information.This section includes the following topics: In all Cisco MDS 9000 Family switches, three SNMP versions are available: SNMPv1, SNMPv2c, and SNMPv3 (see Figure 31-1). SNMP is an application layer protocol that facilitates the exchange of management information between network devices. SNMPv3 CLI User Management and AAA Integration.This chapter includes the following sections: A user configured through the CLI can access the switch using SNMP (for example, the Fabric Manager or the Device Manager) and vice versa. Users, passwords, and roles for all CLI and SNMP users are the same. You can use SNMP to modify a role that was created using the CLI and vice versa. The CLI and SNMP use common roles in all switches in the Cisco MDS 9000 Family.
