Controller Based WLANs

Why does the controller show the “No available license” error when enough AP licenses are available?

Aruba Employee

Product and Software: This article applies to Aruba OS 3.x and later.

Symptom

Campus APs or remote APs cannot come up due to a "No available license" error.

#show log system 10 | include stm
Jan 8 14:27:27 stm[1335]: <305014> <WARN> |stm| No available license for remote AP CV c5:bc:6e
Jan 8 14:28:05 stm[1335]: <305038> <WARN> |stm| No available license for AP 00:1a:1e:c6:76:3a

However, unused campus AP or remote AP license are available.

#show ap license-usage
Total AP Licenses : 8
AP Licenses Used : 6
MUX Licenses Used : 0
Unused AP Licenses : 2
Total RAP Licenses : 16
RAP Licenses Used : 2

Root Cause
Not enough WIP licenses are available.

In ArubaOS 3.3.2 code or later, WIP license capacity must equal the sum of the "campus-connected APs" and "remote APs", up to the "remote AP" platform limit. If there is a mismatch between the WIP license capacity and the sum of campus-connected APs and remote APs, the lower of the two license counts is enforced.

Real Case Example

#show log system 10 | include stm
Jan 8 14:27:27 stm[1335]: <305014> <WARN> |stm| No available license for remote AP CV c5:bc:6e
Jan 8 14:28:05 stm[1335]: <305038> <WARN> |stm| No available license for AP 00:1a:1e:c6:76:3a

In this case, there are only eight WIP licenses, which allow a maximum of eight campus APs or remote APs in the controller. In the "show ap database" command, eight APs are up with license, and four APs are unlicensed (flag: IL). To solve this problem, more WIP licenses must be added to this controller.

Note: The 3.x licensing model for legacy platforms, that is 200, 800, 2400, SC-1, and SC-II, is different and therefore this rule is not applicable.
