Routing

Anyway know of a free way to get a list of top-talkers across a routed interface ?

We spent a ton of money on a new environment only to find that Juniper wants to charge us more to issue a simple show top talkers command. (something that is free in the Cisco world) I have Junos space but not the network director piece.

Any help is appreciated, Thanks,

Justin

Info found on getting this to work in Network Director: 

Requirements for Flow Analysis To perform flow analysis with Network Director, you must: 

Ensure that the components of Cloud Analytics Engine are installed on your network devices and that the Compute Agent discovery file has been created and uploaded to the Data Learning Engine (DLE).

See “Understanding Cloud Analytics Engine and Network Director” on page 16 for more information. •

Specify the DLE IP address under Preferences > Monitoring> Data Learning Engine Settings.

 Enable LLDP on the servers hosting the VMs, on the BMSs, and on the connecting switches. I

n addition, the switches must be discovered by using the SNMP option in Network Director

. See the Cloud Analytics Engine documentation in the QFX Series switch documentation for more information about Cloud Analytics Engine.

Network Director performs flow analysis between VMs and BMSs in the following topologies: •

BMSs connected by a Layer 3 IP fabric •

VMs connected by VMware NSX or OpenStack VXLAN tunnels overlaid on a Layer 3 IP fabric

this is nuts. Still cant figure this out. All I want to do is a simple show top talkers. Something that would have taken 3 minutes in Cisco. Help.

Download a free netflow collector/analyzer:

Configure your router:

set interfaces <interface> unit 0 family inet sampling input
set interfaces <interface> unit 0 family inet sampling output
set forwarding-options sampling input rate 1000
set forwarding-options sampling family inet output flow-server <flow-server> port 2055
set forwarding-options sampling family inet output flow-server <flow-server> source-address <router-ip>
set forwarding-options sampling family inet output flow-server <flow-server> version 5

or switch:

set protocols sflow polling-interval 15
set protocols sflow sample-rate ingress 1000
set protocols sflow sample-rate egress 1000
set protocols sflow source-ip <switch-ip>
set protocols sflow collector <flow-server> udp-port 2055
set protocols sflow interfaces <interface>
