Enabling and Disabling SNMPv1/v2c and SNMPv3
ExtremeWare XOS 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 enable concurrent support, use the following command:
enable snmp access
To prevent any type of SNMP access, use the following command:
disable snmp access
To prevent access using SNMPv1/v2c methods and allow access using SNMPv3 methods only, use the
following commands:
enable snmp access
disable snmp access {snmp-v1v2c}
There is no way to configure the switch to simultaneously allow SNMPv1/v2c access and prevent
SNMPv3 access.
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.
Accessing Switch Agents
To access the SNMP agent residing in the switch, at least one VLAN must have an assigned IP address.
