NETGEAR 8800 User Manual The Simple Book  by Marshall T. Rose ISBN 0-13-8121611-9 Published by Prentice Hall. This section describes the following SNMP topics: • Enabling and Disabling SNMPv1/v2c and SNMPv3 on page 77 • Accessing Switch Agents on page 78 • Supported MIBs on page 78 • Configuring SNMPv1/v2c Settings on page 79 • Displaying SNMP Settings on page 80 • SNMPv3 on page 81 • Message Processing on page 82 • SNMPv3 Security on page 82 • SNMPv3 MIB Access Control on page 86 • SNMPv3 Notification on page 87 Enabling and Disabling SNMPv1/v2c and SNMPv3 XCM8800 can concurrently support SNMPv1/v2c and SNMPv3. The default is both types of SNMP enabled. Network managers can access the device with either SNMPv1/v2c methods or SNMPv3. To allow support for all SNMP access, or SNMPv1/v2c access only, or SNMPv3 access only, use the following command: enable snmp access {snmp-v1v2c | snmpv3} To prevent support for all SNMP access, or SNMPv1/v2c access only, or SNMPv3 access only, use the following command: disable snmp access {snmp-v1v2c | snmpv3} Most of the commands that support SNMPv1/v2c use the keyword snmp; most of the commands that support SNMPv3 use the keyword snmpv3. After a switch reboot, all slots must be in the "Operational" state before SNMP can manage and access the slots. To verify the current state of the slot, use the show slot command. Understanding Safe Defaults Mode and SNMP The safe defaults mode runs an interactive script that allows you to enable or disable SNMP, Telnet, and switch ports. When you set up your switch for the first time, you must connect to the console port to access the switch. After logging in to the switch, you enter safe defaults mode. Although SNMP, Telnet, and switch ports are enabled by default, the script prompts you to confirm those settings. Chapter 3. Managing the Switch | 77
