Wired Intelligent Edge

Hi,

Trying to implement DHCP and ARP snooping on AOS switches with UBT mode on. Will enabling these features on Tunnel-Reserved-Vlan on access switches be enough for all UBT vlans that reside on the core side?

Thanks,
Pavan.

I would think you should enable those features on the controller/gateway, as with UBT all traffic is handled there.

Thanks Herman.

If we have to apply on both switch (Customer's security requirement) and controller,
On switch - trusting uplink port and Tunnel-Reserved-Vlan be enough ?
On Controller - Will configure as normal. Uplink trunk and uplink vlans as trust.

I would not know... probably the best is to check with TAC, or just test it. Not sure if it is supported.
