We have two devices that are connected in the network. A switch and a Linux workstation. Spectrum is not able to create the connection between these two devices.
After enabling the Spectrum AutoDiscovery debug, we see the following in the AutoDiscovery debug file.
- The Linux workstation (Linux_WS) has two MAC addresses:
Device Linux_WS/0x1000277 (Host_Device) has 2 MAC addresses:
1: a4:bf:1:57:4c:34 --> Port Linux_WS_eno1(ifType=6) ,
2: a4:bf:1:57:4c:35 --> Port Linux_WS_eno2(ifType=6) ,
- The switch (Switch) hears the a4:bf:1:57:4c:34 MAC address of the Linux_WS in the switches LLDP table:
Mar 05 08:07:18 LLDP 1: Port Switch_xe-0/0/14(ifType=6) has neighbor A4.BF.1.57.4C.34 (type=4) port A4.BF.1.57.4C.34 (type=3 with desc )
Port Switch_xe-0/0/14(ifType=6) heard Device Linux_WS/0x1000277 (Host_Device) ( LLDP ):
- However, Spectrum is unable to create the connection between the Switch and Linux_WS models:
Mar 05 08:07:19 Port Switch_xe-0/0/14(ifType=6) : Unable to find remote port on device Linux_WS/0x1000277. Discovery Protocol = 400000
Mar 05 08:07:19 Switch_xe-0/0/14(ifType=6) heard 1 ports on remote PDP device Linux_WS/0x1000277. But no PC resolved.
When using the LLDP table to create a connection between two models in Spectrum:
1 - Both models MUST support the LLDP mib
2. Both models MUST "hear" each other in their respective LLDP tables
Release : Any
Component : Spectrum Discovery
Since only the Switch supports the LLDP table, Spectrum does not make the connection between the Switch and Linux_WS models.
This is functioning as designed.
