Nutanix Network Visualization

Hi there.

 

Running on QFX 5100 switches, with Junos 14.1X53-D45.3 it seems that the network hardware / switch part of Prism does not work correctly. I can see my switch, but i can't see any interfaces. SNMP v3 and V2 is enabled and configured, snmpwalk from cvm lists A LOT. Do anyone have this working on Juniper switches?

Re: Nutanix Network Visualization

Correct, it is not supported at the moment likely because parsing Juniper output has not been tested at all. I shared information to make the Juniper switch change the way it outputs the information that seemingly has worked for someone else in the past, but unfortunately that doesn't appear to work in this case. I do see that there is an internal ticket to enhance the discovery tool to properly parse Juniper output but no ETA at the moment.

Hi @m1kkel

 

I don't know if that switch is specifically supported though if it's RFC 2674 compliant it should work. In addition to SNMP LLDP must also be enabled on the the switch for network visualization. Do you know if it is?

 

From the documentation:"

To track and record networking statistics for a cluster, the cluster requires information about the first-hop network switches and the switch ports being used. Switch port discovery is supported with switches that are RFC 2674 compliant. Switch port discovery involves obtaining statistics from the Q-BRIDGE-MIB on the switch and then identifying the MAC address that corresponds to the host. Such discovery is currently best-effort, so it is possible that, at times, an interface might not be discovered." 

 

And:"

Enable LLDP or CDP on the first-hop switches. The visualizer uses LLDP or CDP to determine which switch port is connected to a given host interface. If LLDP or CDP is unavailable, SNMP data is used on a best-effort basis. For information about configuring LLDP or CDP, see the switch manufacturer’s documentation."

Re: Nutanix Network Visualization

Hi there.

 

Thanks for replying. 

 

LLDP is already enabled, and Nutanix see's the vlan interfaces as well. It is just not able to make the visualization, and show port stats. 

 

Any ideas?

Re: Nutanix Network Visualization

I'm not an expert on that functionality but it may be a parsing issue.

 

If you ssh into the AHV host and run the command "lldpctl" what is the output? I can ask someone internally to take a look.

Yeah please do that. Here is the output:

Re: Nutanix Network Visualization

Hi.

 

Did you delete your last post with the update from your colleague regarding 

protocols lldp port-id-subtype interface-name; interface all;

 

??

 

I cant find it in the thread, but i have the reponse in my mail.. just need to know if you withdraw your answer?

Re: Nutanix Network Visualization

I did not delete it and am not sure why it's not showing up. Did the command work to fix the issue?

Re: Nutanix Network Visualization

Weird, because it was there.

 

I will try the command thie evening, remove the switch and readd it again and we will see.

 

I hope it does.

Re: Nutanix Network Visualization

Hello.

 

I ran the command today, but the interfaces are still not showing in Nutanix Prism/hardware/Switch tab.

 

Here is the new output of lldpctl:
