| The LLDP function is disabled on the switch. |
If the LLDP function is disabled on the switch, the switch
cannot obtain the LLDP neighbor information, and the NMS fails to
operate LLDP MIB objects. As a result, the LLDP neighbor information
cannot be obtained through SNMP. |
Run the lldp enable command in the system view to enable
LLDP globally. By default, LLDP is enabled globally and on the interface. |
| The LLDP-MIB objects are not in the default MIB view. |
The LLDP module has two MIB files, that is, HUAWEI-LLDP-MIB
and LLDP-MIB. The root directory of the LLDP-MIB is iso(1).std(0).iso8802(8802).ieee802dot1(1).ieee802dot1mibs(1).lldpMIB(2).
The default MIB view that can be operated by the NMS is 1.3.6.1, and
all LLDP-MIB objects are not in the default MIB view, so the operations
performed on LLDP-MIB objects do not take effect. |
- Run the snmp-agent mib-view included iso-view iso command
to create the MIB view iso-view that can access all MIB objects.
- Run the snmp-agent community { read | write } community-name mib-view iso-view command to grant the access permission on the MIB view iso-view to the NMS.
- Run the snmp-agent sys-info version all command to configure
all SNMP versions on the switch.
