Usage guidelines The snmp-agent command is optional for an SNMP configuration task. The SNMP agent is automatically enabled when you execute any command that begins with snmp-agent except for the snmp-agent calculate-password command. Examples # Enable the SNMP agent. system-view [Sysname] snmp-agent snmp-agent calculate-password Use snmp-agent calculate-password to convert a plaintext key to an encrypted key for authentication or encryption in SNMPv3.

The view-name argument represents a MIB view name, a string of 1 to 32 characters. A MIB view represents a set of accessible MIB objects.
Related commands snmp-agent mib-view snmp-agent group Use snmp-agent group to create an SNMP group and specify its access right. Use undo snmp-agent group to delete an SNMP group.
included in the MIB view. By default, no notify view is configured, which means the agent does not send traps to the NMS. acl acl-number: Specifies a basic ACL to filter NMSs by source IPv4 address. The acl-number argument represents a basic ACL number in the range of 2000 to 2999. In the specified SNMP group, only the NMSs with the IP addresses permitted in the ACL can access the SNMP agent. acl ipv6 ipv6-acl-number: Specifies a basic ACL to filter NMSs by source IPv6 address.
If you have configured SNMPv3 users, change the local SNMP engine ID only when necessary. The change can void the SNMPv3 usernames and encrypted keys you have configured. Examples # Configure the local engine ID as 123456789A. system-view [Sysname] snmp-agent local-engineid 123456789A Related commands snmp-agent usm-user snmp-agent log Use snmp-agent log to enable SNMP logging. Use undo snmp-agent log to restore the default.

Syntax snmp-agent mib-view { excluded | included } view-name oid-tree [ mask mask-value ] undo snmp-agent mib-view view-name Default The system creates the ViewDefault view when the SNMP agent is enabled. In the default MIB view, all MIB objects in the iso subtree but the snmpUsmMIB, snmpVacmMIB, and snmpModules.18 subtrees are accessible.
[Sysname] snmp-agent community read public mib-view mibtest An SNMPv1 NMS in the public community can query the objects in the mib-2 subtree, but not any object (for example, the ipForwarding or ipDefaultTTL node) in the ip subtree.

Default The SNMP proxy agent function is disabled. Views System view Default command level 2: System level Parameters ip ipv4-address: Specifies the IPv4 address of the SNMP agent that uses the SNMP agent proxy service. ipv6 ipv6-address: Specifies the IPv6 address of the SNMP agent that uses the SNMP agent proxy service. Usage guidelines The SNMP proxy agent function is designed for access controllers installed with a SecBlade IAG card.
snmp-agent sys-info Use snmp-agent sys-info to configure system information for the SNMP agent, including the contact, location, and SNMP versions. Use undo snmp-agent sys-info contact and undo snmp-agent sys-info location to restore the default. Use undo snmp-agent sys-info version to disable an SNMP version.
snmp-agent target-host Use snmp-agent target-host to configure a target host for receiving traps sent by the SNMP agent. Use undo snmp-agent target-host to remove settings for an SNMP trap target host.
Make sure the SNMP agent uses the same UDP port number as the target host for traps. If udp-port port-number is not specified, UDP port 162 is used by default. Port 162 is the SNMP-specified port used for receiving traps, and is used by most NMSs, including IMC and MIB Browser. Make sure the SNMP agent uses the same SNMP version as the trap host so the host can receive traps. If none of the keywords v1, v2c, or v3 is specified, SNMPv1 is used.
• authentication: Enables sending authentication failure traps in the event of authentication failure. • coldstart: Sends coldstart traps when the device restarts. • linkdown: Globally enables sending linkDown traps when the link of a port goes down. • linkup: Globally enables sending linkUp traps when the link of a port goes up. • warmstart: Sends warmstart traps when the SNMP restarts. system: Enables system event (private MIB) traps. vrrp: Enables traps for the VRRP module.
Default command level 3: Manage level Usage guidelines The extended linkUp and linkDown traps add interface description and interface type to the standard linkUp and linkDown traps for fast failure point identification. When you configure the snmp-agent trap if-mib link extended command, make sure the NMS supports the extended linkUp and linkDown traps. If not, the NMS will be unable to parse the traps.
Parameters seconds: Specifies the timeout time, in the range of 1 to 2592000 seconds. Usage guidelines The SNMP module sends traps in queues. As soon as the traps are saved in the trap queue, a timer is started. If traps are not sent out until the timer times out (in other words, the holding time configured by using this command expires), the system removes the traps from the trap sending queue. Examples # Configure the holding time of traps in the queue as 60 seconds.
Related commands • snmp-agent target-host • snmp-agent trap enable • snmp-agent trap life snmp-agent trap source Use snmp-agent trap source to specify the source IP address contained in the trap. Use undo snmp-agent trap source to restore the default. Syntax snmp-agent trap source interface-type interface-number undo snmp-agent trap source Default SNMP chooses the IP address of an interface as the source IP address of the trap.

If the cipher and sha keywords are specified, auth-password is a hexadecimal string of 40 characters or a non-hexadecimal string of 57 characters. privacy-mode: Specifies an encryption algorithm for privacy. The encryption algorithms AES, 3DES, and DES are in descending order of security. Higher security means more complex implementation mechanism and lower speed.
command is consistent with the SNMP entity engine ID specified in the snmp-agent calculate-password command. When you execute this command repeatedly to configure the same user (the usernames remain the same, and there is no limitation to other keywords and arguments), the most recent configuration takes effect. For secrecy, all keys, including keys configured in plain text, are saved in cipher text. Remember the username and the plaintext password when you create a user.
Views System view Default command level 3: Manage level Parameters Statistics-interval: Specifies the statistics interval (in seconds) for the user-specified MIB nodes. The value range is 0 to 900.

Syntax reset userlog flow logbuffer Views User view Default command level 2: System level Usage guidelines Flow logs are saved in the cache before being exported to the information center or log server. Clearing flow logs in the cache causes the loss of log information. Use this command with caution. Examples # Clear flow logs in the cache.
You can specify at most two log servers of the same type or different types for a device. There are two types of log servers, the IPv4 flow logging server and the IPv6 flow logging server. If you have already specified two servers, you need to delete one to specify a new one. If you specify a new server that has the same IP address as but has different other information from the current server, the new configuration overwrites the previous one.
