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.
