Default SNMP Configuration

Feature	Default Setting
SNMP agent	Disabled6.
SNMP trap receiver	None configured.
SNMP traps	None enabled except the trap for TCP connections (tty).
SNMP version	If no version keyword is present, the default is Version 1.
SNMPv3 authentication	If no keyword is entered, the default is the noauth (noAuthNoPriv) security
	level.
SNMP notification type	If no type is specified, all notifications are sent.

6 This is the default when the switch starts and the startup configuration does not have any snmp-serverglobal configuration commands.

SNMP Configuration Guidelines

If the switch starts and the switch startup configuration has at least one snmp-serverglobal configuration command, the SNMP agent is enabled.

An SNMP group is a table that maps SNMP users to SNMP views. An SNMP user is a member of an SNMP group. An SNMP host is the recipient of an SNMP trap operation. An SNMP engine ID is a name for the local or remote SNMP engine.

When configuring SNMP, follow these guidelines:

•When configuring an SNMP group, do not specify a notify view. The snmp-server host global configuration command auto-generates a notify view for the user and then adds it to the group associated with that user. Modifying the group's notify view affects all users associated with that group.
