Hello all,
We use somes Nexus 9372PX switches in VXLAN/MP-BGP EVPN topology and we are facing a strange limitation with VNI Number selection can't below 4096, invalid message look like this :
switch(config-evpn)# vni 20 l2 ^ % Invalid number, range is (4096:16777215) at '^' marker.
We used VNI number under 4096 in our IP Fabric and we don't have this limitation with Nexus 9236C. So i have two questions :
1) is it possible to deactivate this limitation by some magical CLI keyword ?
2) is it just NX-OS version limitation ?
Software BIOS: version 07.51 NXOS: version 7.0(3)I4(6) BIOS compile time: 02/15/2016 NXOS image file is: bootflash:///nxos.7.0.3.I4.6.bin NXOS compile time: 3/9/2017 22:00:00 [03/10/2017 07:05:18] Hardware cisco Nexus9000 C9372PX chassis
Solved! Go to Solution.

Hi there,
I believe the full range was added in 7.0(3)I7(x) -- Sample from my lab:
########################## NXOS: version 7.0(3)I4(7) ########################## N9K-VTEP(config)# vlan 10 N9K-VTEP(config-vlan)# vn-segment ? <0-0> Segment-id <4096-16777214> Segment-id <<<<< N9K-VTEP(config-vlan)# vn-segment 1000 ^ % Invalid number, range is (4096:16777214) at '^' marker.

NX-OS 7.0(3)I7(6) is our current long-lived and recommended release as well.
Hope that helps.
