- Privacy - SNMP frames can carry encrypted data. These mechanisms can be combined to provide three levels of security: - No security - Authentication - Authentication and Privacy. Note that for both authentication and privacy to be enabled, two groups with the same name, one with authentication and one with privacy, must be created. A group is a label for a combination of attributes that determines whether members have read, write, and/or notify privileges. Users can be associated with a group. A group is operational only when it is associated with an SNMP user. Model OIDs The following are the switch model Object IDs (OIDs): Model Name PC5524 PC5524P PC5548 PC5548P Object ID 10895.3030 10895.3032 10895.3031 10895.3033 SNMP Global Settings The Engine ID is used by SNMPv3 entities to uniquely identify themselves. An SNMP agent is considered an authoritative SNMP engine. This means that the agent responds to incoming messages (Get, GetNext, GetBulk, Set), and sends Trap messages to a manager. The agent's local information is encapsulated in fields in the message. Each SNMP agent maintains local information that is used in SNMPv3 message exchanges (not relevant for SNMPv1 or SNMPv2). The default SNMP Engine ID is comprised of the enterprise number and the default MAC address. The SNMP engine ID must be unique for the administrative domain, so that no two devices in a network have the same engine ID. Dell PowerConnect 55xx Systems User Guide 309
