Syntax snmp-server engineID local {engineid-string | default } no snmp-server engineID local • engineid-string - The character string that identifies the engine ID. The engine ID is a concatenated hexadecimal string. Each byte in hexadecimal character strings is two hexadecimal digits. Each byte can be separated by a period or colon. (Range: 6-32 characters) • default - The engineID is created automatically, based on the device MAC address. Default Configuration The engineID is not configured. Command Mode Global Configuration mode User Guidelines If you want to use SNMPv3, you need to specify an engine ID for the device. You can specify your own ID or use a default string that is generated using the MAC address of the device. If the SNMPv3 engine ID is deleted, or the configuration file is erased, then SNMPv3 cannot be used. Since the EngineID should be unique within an administrative domain, the following guidelines are recommended: 1. For standalone devices use the default keyword to configure the Engine ID. 2. For stackable systems, configure your own EngineID, and verify that is unique within your administrative domain. Changing the value of snmpEngineID has important side-effects. A user's password (entered on the command line) is converted to an MD5 or SHA security digest. This digest is based on both the password and the local engine ID. The command line password is then destroyed, as required by RFC 2274. Because of this deletion, if the local value of engineID changes, the security digests of SNMPv3 users will be invalid, and the users will have to be reconfigured. Example The following example configures the Engine ID automatically. console(config)# snmp-server engineID local default snmp-server filter Use the snmp-server filter command in Global Configuration mode to create or update a Simple Network Management Protocol (SNMP) server filter entry. To remove the specified SNMP server filter entry, use the no form of this command. 1051
