Analytics topology with vrf

EF — Wed, 21 Feb 2024 19:47:10 GMT

Hi Team!!

I have an analytics engine and XIQ-SE doesn't show any graph and/or flow data.

I verified with tcp dump that no traffic is reaching it from VSPs.

The VSPs configuration:

- separated VRF from GRT (user defined) to split Telemetry and sFlow from customer traffic.
- interface vlan with IP address (on this VRF) in the same subnet of Analytics engine as agent IP

Two more:

- All the VSPs are able to reach the IP of Analytics with ping.
- This interface vlan is not from nls module (is not mgmt vlan )

Is this topology allowed, int vlan from user defined VRF?

Best!!!

Hi Team,

I found the solution my self, I read this:

"sFlow supports user created VRFs when Segmented Management Instance CLIP interface IP address is used as the sFlow source IP"

So it seems that int vlan in user defined VRF doesnt work.

I did a lab with CLIP MGMT on user defined VRF and it works, Here the commands, maybe is usefully for someone:

- VSP

ip vrf analytics vrfid 10

vlan create 10 name "SERVER" type port-mstprstp 0
vlan i-sid 10 444410
interface Vlan 10
vrf analytics
ip address 192.168.1.100 255.255.255.0
exit

mgmt clip vrf analytics
ip address 1.1.1.1/32
enable
exit

sflow agent-ip 1.1.1.1
sflow enable
sflow collector 1 address 192.168.1.99
sflow collector 1 owner SRVLABANALYTICS

app-telemetry enable

int giga X/X

sflow sampling-rate 8192
sflow collector 1

- Analytics, route the IP loopbak

Best!!
