Nexus 9372 Vxlan VNI number limitation

C3H5N3O9
Level 1
Level 1

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

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 ?

                              ^

                       ^

N9K-VTEP(config-evpn-evi)# route-target import auto
N9K-VTEP(config-evpn-evi)# route-target export auto
<snip>

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

 

Hope that helps.
