Hello, I have instantiated a new cluster and I can’t seem to figure out why the Network Visualization won’t work for my cluster. LLDP is enabled on my Meraki switch. I can see when new devices join my network as Nutanix on both my eero and firewalla. When I do lldpctl from the host it shows the following:-------------------------------------------------------------------------------LLDP neighbors:-------------------------------------------------------------------------------Interface: eth0, via: LLDP, RID: 1, Time: 1 day, 01:01:39 Chassis: ChassisID: mac ac:17:c8:2f:de:80 SysName: Home - switch SysDescr: Meraki MS225-24P Cloud Managed PoE Switch MgmtIP: x.x.x.x Capability: Bridge, on Port: PortID: ifalias 9 PortDescr: Port 9 TTL: 120 VLAN: 1, pvid: yes Unknown TLVs: TLV: OUI: 00,18,0A, SubType: 1, Len: 4 00,2C,32,89-------------------------------------------------------------------------------Interface: eth1, via: LLDP, RID: 1, Time: 1 day, 01:01:38 Chassis: ChassisID: mac ac:17:c8:2f:de:80 SysName: Home - switch SysDescr: Meraki MS225-24P Cloud Managed PoE Switch MgmtIP: x.x.x.x Capability: Bridge, on Port: PortID: ifalias 15 PortDescr: Port 15 TTL: 120 VLAN: 1, pvid: yes Unknown TLVs: TLV: OUI: 00,18,0A, SubType: 1, Len: 4 00,2C,32,89------------------------------------------------------------------------------- When I search the health_server.log I see the following errors:2024-08-08 13:00:36,222Z INFO scheduler.py:472 Sch:SCH_0 Pool Exec Count 316 Executing Plugin (task, id: 21, name: switch_interface_stats_collector, scope: Local)2024-08-08 13:00:36,223Z INFO scheduler.py:128 [switch_interface_stats_collector] PID 30898 Exec Count 316 Started the execution of pool task (task, id: 21, name: switch_interface_stats_collector, scope: Local).2024-08-08 13:00:36,224Z INFO ncc_task.py:430 [switch_interface_stats_collector] Timeout for switch_interface_stats_collector is 1230 seconds2024-08-08 13:00:36,227Z INFO base_plugin.py:1835 [switch_interface_stats_collector] Check name = collect_interface_stats2024-08-08 13:00:36,228Z INFO network_config_manager.py:47 [switch_interface_stats_collector] NWVIZ: Reading the network configuration from Zookeeper.2024-08-08 13:00:36,229Z INFO scheduler_job_queue_manager.py:362 Adding task: (task, id: 65, name: ahv_remote_log_forwarding_check, scope: Local) Init Delay: 52024-08-08 13:00:36,230Z ERROR network_config_manager.py:202 [switch_interface_stats_collector] NWVIZ: Could not parse switch configuration - Error parsing message.2024-08-08 13:00:36,230Z ERROR network_config_manager.py:77 [switch_interface_stats_collector] NWVIZ: Empty/Invalid network configuration received.

Meraki Switch Unknown in Network Visualization

Hello,

I have instantiated a new cluster and I can’t seem to figure out why the Network Visualization won’t work for my cluster. LLDP is enabled on my Meraki switch. I can see when new devices join my network as Nutanix on both my eero and firewalla.

When I do lldpctl from the host it shows the following:

Is there a requirement for me to use SMTP or shouldn’t LLDP/CDP be enough.

Page 1 / 1

To have this (the info at the right) I always need to enable SNMP on the switch and configure this in SNMP under settings in prism element.

LLDP will only give me this information:

@JeroenTielen

Thanks for the info. So I added the Switch information where I think it needed to be added.

I can see the switch now on the switch configuration

Still showing up as unknown / data unavailable on the visualization page.

I know that the SNMP is working on the switch correctly because I can walk the switch with the credentials I set up from a different device no problem.

I dig through the logs some more.

I”m not sure if you’ve seen this document yet: https://portal.nutanix.com/page/documents/kbs/details?targetId=kA032000000TVfiCAG

However you’ll note in the lldpctl data the interfaces are labeled as ‘ifAlias’ and not ‘ifname’, this may be the reason the port information is not populating.

If you added the SNMP configuration correctly (and the cluster has access to it) then you need to wait before it will be shown. We are almost a day further at the moment of writing this, so it should be visible now :P

If not, the link from Kurt above is really helpful.

Thanks guys!

@ktelep - I did see this page and to be honest, I got caught up on it saying local vs ifalias/ifname in Issue 1. I have a ticket opened with Meraki.

FYI, Meraki doesn’t support interface name only interface alias. Thanks for all your help.
