Managing the Switch
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.
Accessing Switch Agents
To access the SNMP agent residing in the switch, at least one VLAN must have an assigned IP address.
By default, SNMP access and SNMPv1/v2c traps are enabled. SNMP access and SNMP traps can be
disabled and enabled independently—you can disable SNMP access but still allow SNMP traps to be
sent, or vice versa.
Supported MIBs
In addition to private MIBs, the switch supports the standard MIBs listed in Appendix C.
Configuring SNMPv1/v2c Settings
The following SNMPv1/v2c parameters can be configured on the switch:
• Authorized trap receivers—An authorized trap receiver can be one or more network management
stations on your network. The switch sends SNMPv1/v2c traps to all configured trap receivers. You
can have a maximum of 16 trap receivers configured for each switch, and you can specify a
community string and UDP port individually for each trap receiver. All community strings must also
be added to the switch using the
configure snmp add community command.
To configure a trap receiver on a switch, use the following command:
configure snmp add trapreceiver <ip_address> community [[hex <hex_community_name>]
| <community_name>] {port <port_number>} {from <src_ip_address>} {mode <trap_mode>
[enhanced | standard]}
You can delete a trap receiver using the configure snmp delete trapreceiver command.
• Community strings—The community strings allow a simple method of authentication between the
switch and the remote network manager. There are two types of community strings on the switch:
— Read community strings provide read-only access to the switch. The default read-only
community string is public.
— Read-write community strings provide read- and-write access to the switch. The default
read-write community string is private.
• System contact (optional)—The system contact is a text field that enables you to enter the name of
the person(s) responsible for managing the switch.
