How to enable the listen of the SNMP global IPv6 address?

[angelyouyou]

I'm using Cisco ISO 7200 (15.2M11) release product. When I enable SNMP, I cannot get the SNMP information of the device through the IPv6 global address, but I can get the device information through SNMP normally through the IPv4 address. Check the listening UDP port and find that the device only enables the listen port of link-local address of the SNMP link. How to enable the listen of the SNMP global IPv6 address?

Below is my topology, I am using g0/0 on R1 to connect my computer.

I have attached my config file of R1 router.

My computer has already got the  global IPv6 address by SLLAC.

Hi @angelyouyou ,

You should be able to poll the device using IPv6 using the global unicast address, even though the "show udp" states that the device is listening on the link local address.

Did you try to perform a snmpget or snmpwalk from the workstation using the IPv6 address of the router?

Thanks very much.

You're right. IPv6 SNMP server is not relate with IPv6 address UDP status (caused a bit of confusion), even there're only link-local address were listened.

MG-SOFT MIB Browser(v10.0) can not send IPv6 SNMP request after I captured the packet, maybe some settings are wrong.

When I use another SNMP client util(iReasoning MIB Browser), I can get or walk SNMP information by IPv6 address communicated with Cisco Router.My problem was solved.
