An admin has created a RUCKUS GRE tunnel profile in SmartZone. Why is the new tunnel unavailable in the GRE Tunnel Profile dropdown when configuring…

In the RUCKUS SmartZone management platform, configuration objects are organized hierarchically and scoped by AP Zones. An AP Zone is a logical grouping of Access Points that share a common configuration. For a GRE tunnel profile to be usable by a WLAN, it must first be explicitly associated with the AP Zone in which the WLAN is being configured. If the administrator creates the GRE tunnel profile but fails to assign it to the target AP Zone, the profile will not be visible or available for selection in the dropdown menu during the WLAN configuration process for that specific zone.

A. WLAN does not support GRE tunnels.

This is factually incorrect. RUCKUS WLANs fully support tunneling client traffic over GRE to a centralized controller or gateway.

B. A split tunnel profile has not been created.

Split tunneling is an optional feature, not a prerequisite. A standard (non-split) GRE tunnel profile should be visible if correctly associated.

C. The maximum GRE tunnel count has been reached.

This would prevent the creation of a new tunnel profile, not cause an existing, successfully created profile to be hidden from the selection list.

1. RUCKUS SmartZone 5.2.1 Administrator Guide: In the section "Creating a Ruckus GRE Tunnel Profile," Step 5 explicitly states: "In AP Zones, select the AP zones to which you want to apply this profile." This step confirms that associating the profile with an AP Zone is a mandatory part of the configuration process for it to be applied. (Page 578)

2. RUCKUS SmartZone 6.1.0 Administrator Guide: Chapter 25, "Working with AP Zones," explains that AP zones are logical groupings where specific configurations, including WLANs, are applied. This establishes the principle that configurations are zone-dependent. The guide for creating a WLAN (Chapter 27) is performed within the context of a zone, which inherits available profiles like GRE tunnels that have been associated with it.
