Link Layer Discovery Protocol (LLDP) on Huawei S3300

Download as PDF

The Link Layer Discovery Protocol (LLDP) is an layer 2 discovery protocol defined in the IEEE 802.1ab. How does it work? The LLDP protocol collects information about local interfaces, sends this information to neighbours, and receives information from the neighbours as well. In short, when the LLDP protocol runs on devices, the NMS can obtain the Layer 2 information about all the devices it connects and the detailed network topology. It does it by searching the layer 2 information in Management Information Base (MIB). NMS uses LLDP management address to identify the device. Trap message is triggered in case when local management address is changed, LLDP is enabled or disabled globally and there are changes on neighbouring devices.

Lets try to configure LLDP based on the following topology:Huawei S3300 LLDP topology

First of all configure SNMP trap for LLDP:

[Switch]snmp-agent trap enable feature-name lldptrap

[Quidway]dis snmp-agent tr feature-name lldptrap all
------------------------------------------------------------------------------
Feature name: LLDPTRAP                      
Trap number : 4         
------------------------------------------------------------------------------
Trap name                       Default switch status   Current switch status 
lldpRemTablesChange             on                      on                  
hwLldpEnabled                   on                      on                  
hwLldpDisabled                  on                      on                  
hwLldpLocManIPAddrChange        on                      on

And now turn on traps to be displayed on the screen:

<Switch>terminal monitor 
Info: Current terminal monitor is on.
<Switch>terminal trapping 
Info: Current Terminal trapping is on.

Enable LLDP globally and look what kind of trap will be displayed:

[Switch]lldp enable
Info: Global LLDP is enabled successfully.

Configure LLDP management address:

Info: Setting management address successfully.

Now change physical parameters of neighbouring interfaces and trap will be send to NMS that LLDP neighbour information is changed:

If you want to test it on eNSP, unfortunately I was not able to do it. It looks like LLDP is not supported yet, even the necessary commands are available.
