SNMP over IPv6Last Updated: July 23, 2012
Simple Network Management Protocol (SNMP) can be configured over IPv6 transport so that an IPv6 host can perform SNMP queries and receive SNMP notifications from a device running IPv6. Finding Feature InformationYour software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module.

Information About SNMP over IPv6SNMP over an IPv6 TransportSimple Network Management Protocol (SNMP) can be configured over IPv6 transport so that an IPv6 host can perform SNMP queries and receive SNMP notifications from a device running IPv6 software. The SNMP agent and related MIBs have been enhanced to support IPv6 addressing. This feature uses the data encryption standard (3DES) and advanced encryption standard (AES) message encryption. How to Configure SNMP over IPv6Configuring an SNMP Notification Server over IPv6Use an SNMP community string to define the relationship between the SNMP manager and the agent. The community string acts like a password to regulate access to the agent on the device. Optionally, you can specify one or more of the following characteristics associated with the string:
You can configure one or more community strings. To remove a specific community string, use the no snmp-server community command. The snmp-server host command specifies which hosts will receive SNMP notifications, and whether you want the notifications sent as traps or inform requests. The snmp-server enable traps command globally enables the production mechanism for the specified notification types (such as Border Gateway Protocol [BGP] traps, config traps, entity traps, and Hot Standby Router Protocol [HSRP] traps). DETAILED STEPS Configuration Examples for SNMP over IPv6Examples: Configuring an SNMP Notification Server over IPv6The following example permits any SNMP to access all objects with read-only permission using the community string named public. The device also will send Border Gateway Protocol (BGP) traps to the IPv4 host 172.16.1.111 and IPv6 host 3ffe:b00:c18:1::3/127 using SNMPv1 and to the host 172.16.1.27 using SNMPv2c. The community string named public will be sent with the traps. Device(config)# snmp-server community public Device(config)# snmp-server enable traps bgp Device(config)# snmp-server host 172.16.1.27 version 2c public Device(config)# snmp-server host 172.16.1.111 version 1 public Device(config)# snmp-server host 3ffe:b00:c18:1::3/127 public Example: Associate an SNMP Server Group with Specified ViewsIn the following example, the SNMP context A is associated with the views in SNMPv2c group GROUP1 and the IPv6 named access list public2: Device(config)# snmp-server context A Device(config)# snmp mib community-map commA context A target-list commAVpn Device(config)# snmp mib target list commAVpn vrf CustomerA Device(config)# snmp-server view viewA ciscoPingMIB included Device(config)# snmp-server view viewA ipForward included Device(config)# snmp-server group GROUP1 v2c context A read viewA write viewA notify access ipv6 public2 Example: Create an SNMP Notification ServerThe following example configures the IPv6 host as the notification server: Device> enable Device# configure terminal Device(config)# snmp-server community mgr view restricted rw ipv6 mgr2 Device(config)# snmp-server engineID remote 3ffe:b00:c18:1::3/127 remotev6 Device(config)# snmp-server group public v2c access ipv6 public2 Device(config)# snmp-server host host1.com 2c vrf trap-vrf Device(config)# snmp-server user user1 bldg1 remote 3ffe:b00:c18:1::3/127 v2c access ipv6 public2 Device(config)# snmp-server enable traps bgp Device(config)# exit Additional ReferencesRelated Documents
