CISCO ASA 5505 - Do I need a license to configure trunk ports?

[c.mcauley1]

I currently have the base license with the CISCO ASA 5505. Do I need to purchase the Security Plus license or any other "trunking license" in order to be able to configure trunk ports? Or is trunking enabled by default? Thanks.

EDIT: And if I do indeed need  Security Plus license, where can I purchase this separately? (As I already have the ASA 5505 with Base license)

Hi 

I didnt think you could enable trunking on the ASA ? 

I did try to enable VTP on ASA but it didnt work ?

Trunking is only available with the SecurityPlus license which you can buy at your preferred Cisco reseller.

But as this license is quite expensive, also consider to migrate to a new 5506-X as the 5505 is legacy technology and approaching EOL in the near future.

@aaronkb2002: VTP is not available on the ASA and typically not needed as the ASA has only to know a subset of the VLANs available on the switches.

Thanks very much for this answer. This was exactly what I needed.
