L2 Gateway VXLAN Configuration capability error on VDX8770

[thaizoun]

Greeting,

I am trying to configure a VXLAN Tunnel on a VDX8770 device. The VDX8770 is running code 7.0.d4 and when i started implementing the L2 VXLAN configuration , i got the following error 

rb1(config-rbridge-id-4)# overlay-gateway VXLAN-GW

rb1(config-overlay-gw-VXLAN-GW)#  type layer2-extension

rb1(config-overlay-gw-VXLAN-GW)# attach rbridge-id add 4

%Error : Some of specified rbridges are not overlay capable

I am configuring  the VDX8770 (rb4) from the principal fabric  switch 6740 (rb1). both VDX switches are running the same NOS code.
When attached rbridge-id 1 instead of 4 (rb4) , the VXLAN tunnel was built 

rb1(config-rbridge-id-4)# overlay-gateway VXLAN-GW

rb1(config-overlay-gw-VXLAN-GW)#  type layer2-extension

rb1(config-overlay-gw-VXLAN-GW)# attach rbridge-id add 4

%Error : Some of specified rbridges are not overlay capable

rb1(config-overlay-gw-VXLAN-GW)# attach rbridge-id add 1

rb1(config-overlay-gw-VXLAN-GW)# map vlan 10 vni 1012

rb1(config-overlay-gw-VXLAN-GW)#  site SITE-A

rb1(config-site-SITE-A)#   ip address 10.20.4.4

2021/10/22-13:45:27, [NSM-1004], 600, SW/0 | Active | DCE, INFO, rb1,  Interface Tunnel 61441 is created.

2021/10/22-13:45:27, [NSM-1010], 601, SW/0 | Active | DCE, INFO, rb1,  InterfaceMode changed from None to L2 for interface Tunnel     61441.

I am wondering if the VDX 8770 is not VXLAN capable or it needs a license . I cannot use 6740  for various reasons .

Any feedback is greatly appreciated .

Talal,

This is expected behavior.  The 8770 does not support VXLAN, per the NOS L2 guide which refers to it as a "VXLAN-incapable aggregation switch (such as a Brocade VDX 8770)".  The guide details how to correctly setup VXLAN using the 6740 or 6940 devices and can be found here:

NOS 7.0.0 Layer 2 Switching Guide

Hi Michael,

Thank you kindly for responding to my question and for providing the L2 NOS guide.

I am still new to the VDXs in general .

I am very grateful for having this community to  post questions and help each other

Thanks again
