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 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:
Note
It is recommended to use a different community name for the trap receiver and other SNMP (Simple Network Management Protocol) read/write operations.

configure snmp add trapreceiver [ip_address | ipv6_address] community [[hex hex_community_name] | community_name] {port port_number} {from [src_ip_address | src_ipv6_address]} {vr vr_name} {mode trap_mode}
To configure the notification type (trap/inform), use the following command specifying trap as the type:
configure snmpv3 add notify [[hex hex_notify_name] | notify_name] tag [[hex hex_tag] | tag] {type [trap | inform]}{volatile}
To delete a trap receiver on a switch, use the following command:
configure snmp delete trapreceiver [[ip_address | ipv6_address] {port_number} | all]
Entries in the trap receiver list can also be created, modified, and deleted using the RMON2 trapDestTable MIB table, as described in RFC 2021.
SNMP INFORM—SNMP INFORM allows for confirmation of a message delivery. When an SNMP manager receives an INFORM message from an SNMP agent, it sends a confirmation response back to the agent. If the message has not been received and therefore no response is returned, the INFORM message is resent. You can configure the number of attempts to make and the interval between attempts.

To configure the notification type (trap/inform), use the following command specifying inform as the type:
configure snmpv3 add notify [[hex hex_notify_name] | notify_name] tag [[hex hex_tag] | tag] {type [trap | inform]}{volatile}
To configure the number of SNMP INFORM notification retries, use the following command:
configure snmpv3 target-addr [[hex hex_addr_name] | addr_name] retry retry_count
To configure the SNMP INFORM timeout interval, use the following command:
configure snmpv3 target-addr [[hex hex_addr_name] | addr_name] timeout timeout_val
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.
To store and display the SNMP community string in encrypted format, use the following command:
configure snmpv3 add community [[hex hex_community_index] | community_index] [encrypted name community_name | name [[hex hex_community_name] | community_name] {store-encrypted} ] user [[hex hex_user_name] | user_name] {tag [[hex transport_tag] | transport_tag]} {volatile}
Note
SNMP community string name can contain special characters.
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.
System name (optional)—The system name enables you to enter a name that you have assigned to this switch. The default name is the model name of the switch (for example, BD-1.2).
System location (optional)—Using the system location field, you can enter the location of the switch.
