Why do operations on the lldpNotificationInterval fail after LLDP is enabled globally on an S series switches

6

For Huawei S series switches (except the S1700), the lldpNotificationInterval object is in LLDP-MIB.mib. The root object of LLDP-MIB.mib is iso(1).std(0).iso8802(8802).ieee802dot1(1).ieee802dot1mibs(1).lldpMIB(2). The default MIB views operable to the NMS have an OID prefix 1.3.6.1. The lldpNotificationInterval object is not in any operable MIB view, so the operations performed on the lldpNotificationInterval object on the NMS do not take effect.

To make operations on the lldpNotificationInterval object performed on the NMS take effect, perform the following configuration on the managed device:
[HUAWEI] snmp-agent mib-view included test iso
[HUAWEI] snmp-agent community read huawei123 mib-view test
[HUAWEI] snmp-agent community write huawei123 mib-view test
[HUAWEI]snmp-agent sys-info version all
The community name (huawei123) and MIB view name (test) in the preceding commands are used as an example. You can change them as required.

How to configure LLDP on S series switches
On Huawei S series switches (except the S1700), LLDP can be enabled globally or on a specified interface. For example: 1. Enable LLDP globally. [HUAWEI] lldp enable 2. Enable LLDP on GigabitEthernet0/0/1 of SwitchA. [HUAWEI] interface gigabitethernet 0/0/1 [HUAWEI-GigabitEthernet0/0/1] lldp enable

Some services are interrupted after IPSG is configured on an S series switch. Why
If some services are interrupted after IPSG is configured on an S series switch (except the S1700), possible causes include the following: 1. DHCP snooping is not enabled on a DHCP terminal or the DHCP terminal does not obtain an IP address again after DHCP snooping is enabled. As a result, the dynamic binding table does not contain correct information about the terminal. IP packets sent by the terminal are discarded, and the terminal cannot communicate with the network. Solution: Enable DHCP snooping on the terminal and make the terminal obtain an IP address again to generate a dynamic binding entry in the binding table. 2. No static binding entry corresponding to a static user is generated. As a result, the user cannot go online. Solution: Create a static binding entry for each authorized user connected to the switch. Note: After the ip source check user-bind enable command is configured on an interface or in a VLAN. The interface or VLAN matches all received IP packets against a binding table and discards those not matching the binding table.

The dhcp select global command is added to the VLANIF interface view after S series switch is upgraded
On fixed switches running V100R003, the DHCP server function (the dhcp select global command) is enabled in the VLANIF view by default, and there is no buildrun information. On fixed switches running V100R005 or a later version, the DHCP server function is disabled in the VLANIF view by default. To ensure compatibility with earlier versions, the DHCP server function is enabled in the VLANIF view after an upgrade. If the DHCP function (the dhcp enable command) is disabled globally, the dhcp select global command will not take effect, and you can manually delete this command. If the DHCP function (the dhcp enable command) is enabled globally after the upgrade, contact Huawei technical support for help before deleting the dhcp select global command.

What should I do if an S series switches fails to discover LLDP neighbors
If a Huawei S series switch (except the S1700) fails to discover LLDP neighbors, the solutions are as follows: 1. Ensure that LLDP is enabled globally on the local switch and not disabled on related interfaces. 2. Ensure that LLDP is enabled globally on the peer switch and not disabled on related interfaces. 3. Ensure that the BPDU processing function is enabled on the related interfaces on the local and peer switches, and no other policy is used to discard LLDP BPDUs.

Is the network affected after LLDP is configured on an S series switch
S series switches (except the S1700) use LLDP to discover link information, which does not affect the network.
