ALE OmniSwitch stack does not form due to incompatible licenses
Table of Contents
Today I saw an interesting behaviour of two Alcatel-Lucent Enterprise OmniSwitch 6450. Both switches has been configured as a stack, but one of the switches showed a flashing ID after the startup, and the stack was not formed. While I checked the logs and the status of the stack, I noticed that the slot number was incorrect. Furthermore the status showed “INC-LIC”.

According to the stack status and the switch logs, there seems to be a problem with the licenses. So I checked the installed licenses on both switches. On switch showed Metro license:
-> show license info NI Application License Type Time Left ———–+———————+—————————+————– 1 METRO Permanent 0 1 10G Permanent 0 1001 10G Permanent 0
The other switch not:
-> show license info NI Application License Type Time Left ———–+———————+—————————+————– 1 10G Permanent 0
Don’t be confused because of the slot numbering. I pulled the stacking cable.
The solution was easy: I removed the metro license and after a reboot of the switch, from which I removed the license, the stack formed properly.
