System SNMP Configuration Menu
Alteon supports SNMP-based network management. In the SNMP model of network management, a management station (client/manager) accesses a set of variables known as MIBs (Management Information Base) provided by the managed device (agent). If you are running an SNMP network management station on your network, you can manage Alteon using the following standard SNMP MIBs:
*MIB II (RFC 1213)
*Ethernet MIB (RFC 1643)
*Bridge MIB (RFC 1493)
An SNMP agent is a software process on the managed device that listens on UDP port 161 for SNMP messages. Each SNMP message sent to the agent contains a list of management objects to retrieve or to modify. SNMP parameters that can be modified include:
*System name
*System location
*System contact
*Use of the SNMP system authentication trap function
*Read community string
*Write community string
*Trap community strings
Notes
*If the traps are configured to be sent from an SNMP data port, the source address of the received trap is the IP of the interface defined in the /cfg/sys/ssnmp/trsrc command.
*If the traps are configured to be sent from an SNMP management port, the source address of the received traps is the management interface IP.
*SNMP-v1 traps do not support IPv6 addresses. If an IPv6 address is configured, the SNMP-v1 trap will send the first 4 octets of the IPv6 address in the agent-addr field in place of an IPv4 address.

Command Syntax and Usage
snmpv3
 
Displays the SNMPv3 menu. To view this menu, see /cfg/sys/ssnmp/snmpv3 SNMPv3 Configuration Menu.
name <new string (maximum 64 characters)>
 
Configures the name for the system.
Values: 1 – 64 characters
Note: Only use non-special alphanumeric characters.
locn <new string (maximum 64 characters)>
 
Configures the name of the system location.
Values: 1 – 64 characters
cont <new string (maximum 64 characters)>
 
Configures the name of the system contact.
Values: 1 – 64 characters
rcomm <SNMP read community name(s), max 32 chars per community name, up to 15 community names with pipe delimiter>
 
Configures the SNMP read community string. The read community string controls SNMP get access to Alteon.
Values: Up to 32 characters per community name, up to 15 community names with pipe (|) delimiter.
Default: public
wcomm <SNMP write community name(s), max 32 chars per community name, up to 15 community names with pipe delimiter>
 
Configures the SNMP write community string. The write community string controls SNMP set and get access to Alteon.
Values: Up to 32 characters per community name, up to 15 community names with pipe (|) delimiter.
Default: private
trsrc <interface number (1-256)>
 
Defines the interface number for SNMP trap source interface. This command lets you select one of the configured interfaces as the source interface using the interface number.
Note: This command is applicable only to SNMPv1 and SNMPv2 traps because only they contain the source IP address that can be set with this command. The SNMPv3 packets do not contain this field.
Note: This command is relevant only if the SNMP traps are configured to be sent from an Alteon data port (/cfg/sys/mmgmt/snmp data).
trap1 <new SNMP trap host IP address v4 or v6)>
 
Sets the first SNMP trap host address.
The following prompts appear when using this command:
Current first SNMP trap host address:
Enter first SNMP trap host address (v4 or v6):
trap2 <new SNMP trap host IP address v4 or v6)>
 
Sets the second SNMP trap host address.
The following prompts appear when using this command:
Current second SNMP trap host address:
Enter second SNMP trap host address (v4 or v6):
timeout <SNMP state machine timeout minutes, 1-30>
 
Defines the timeout period for the SNMP state computer. When you use diff and apply, memory is allocated to store the output of the command. The timeout period determines when the resources/memory allocated for the output will be freed.
auth disable|enable
 
Enables or disables the use of the system authentication trap facility.
Default: disable
linkt <port disable|enable>
 
Enables or disables the sending of SNMP link up and link down traps.
Default: enable
cur
 
Displays the current SNMP service settings.
