Selectively enables SNMP access on the switch.

Disabled.
To have access to the SNMP agent residing in the switch, at least one This command is available on the ExtremeSwitching X440-G2, X450-G2, X460-G2, X465, X590, X620, and X695 series switches. must have an IP address assigned to it.
Any network manager running SNMP can manage the switch for v1/v2c/v3, provided the MIB is installed correctly on the management station. Each network manager provides its own user interface to the management facilities.
For SNMPv3, additional security keys are used to control access, so an SNMPv3 manager is required for this type of access.
This command allows you to enable either all SNMP access, no SNMP access, v1/v2c access only, or v3 access only.
To prevent any SNMP access, use the following command : disable snmp access {snmp-v1v2c | snmpv3}
ExtremeXOS 11.2 introduced the concept of safe defaults mode. 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.
If you choose to keep the default setting for SNMP—the default setting is enabled—the switch returns the following interactive script:
Since you have chosen less secure management methods, please remember to increase the security of your network by taking the following actions: * change your admin password * change your SNMP public and private strings * consider using SNMPv3 to secure network management traffic
In addition, you can return to safe defaults mode by issuing the following command: configure safe-default-script
If you return to safe defaults mode, you must answer the questions presented during the interactive script.
For more detailed information about safe defaults mode, see the Using Safe Defaults Mode section in the ExtremeXOS 32.1 User Guide .
The following command enables all SNMP access for the switch:
enable snmp access
This command was first available in ExtremeXOS 10.1.
SNMPv3 was added to ExtremeXOS 12.2. It was also included in ExtremeXOS 11.6.4 and 12.1.2.
This command is available on ExtremeSwitching X435, X440-G2, X450-G2, X460-G2, X465, X590, X620, and X695 series switches.
