Scenario 3: NMS uses SNMP v3 to obtain information from the switch.

The configuration on the switch is listed below:

Switch(config)#snmp

-server

Switch

(config)#snmp-server user tester UserGroup authPriv auth md5 hellotst

Switch

(config)#snmp-server group UserGroup AuthPriv read max write max notify max

Switch(config)#snmp-server view max 1 include

Scenario 4: NMS wants to receive the v3Trap messages sent by the switch.

The configuration on the switch is listed below:

Switch(config)#snmp

-server enable

Switch(config)#snmp

-server host 10.1.1.2 v3 authpriv tester

Switch(config)#snmp-server enable traps

Scenario 5: The IPv6 address of the NMS is 2004:1:2:3::2; the IPv6 address of the switch (Agent) is

2004:1:2:3::1. The NMS network administrative software uses SNMP protocol to obtain data from the switch.

The configuration on the switch is listed below:

Switch(config)#snmp

-server enable

Switch(config)#snmp

-server community rw private

Switch(config)#snmp

-server community ro public

Switch(config)#snmp-server securityip 2004:1:2:3::2

The NMS can use private as the community string to access the switch with read-write permission, or use

public as the community string to access the switch with read-only permission.

Scenario 6: NMS will receive Trap messages from the switch (Note: NMS may have community string

verification for the Trap messages. In this scenario, the NMS uses a Trap verification community string of

dcstrap).

The configuration on the switch is listed below:

Switch(config)#snmp

-server host 2004:1:2:3::2 v1 dcstrap

Switch(config)#snmp-server enable traps

4.4.6 SNMP Troubleshooting

When users configure the SNMP, the SNMP server may fail to run properly due to physical connection failure

and wrong configuration, etc. Users can troubleshoot the problems by following the guide below:

 Good condition of the physical connection.

 Interface and datalink layer protocol is Up (use the “show interface” command), and the connection

between the switch and host can be verified by ping (use “ping” command).
