L2 vxlan evpn on catalyst switch 9500/9600 network

[Deepak Bansal]

Hi Experts,

we have l2 vxlan evpn network.The l3 of the end-host is configured on nexus7k.what we notice that the end-host not able to reach to gateway I.e VIP HSRP.

When we clear the ARP on the gateway it started working. 

My question is if ARP supression works in l2 vxlan evpn? We can see the evpn route for gateway on our VTEPs. 

can someone share me the command to check arp supression table on catalyst 9500/9600. On nexus switch it’s show ip arp supression-cache vlan xxx but I’m not able to find the equivalent command on catalyst switch.

Best Regards,

Deepak

I found the command - show ip device-tracking database

This command will show you if ARP is dropped by vxlan fabric or it forward as unicast packet to destinaiton VTEP where gateway is configured.

Thanks
