ATA DLU/Essential Licenses

[billybjo1]

We recently purchased a number of licenses for adding some ATA187 ports to a CUCM 8.0 system.

We didn't receive any PAK/Serial number and are being told none are issued for Essential licenses. Is that correct?

The ATA ports will still each use 1 DLU, so surely there must be a license file to load. We do have spare DLUs, so it won't prevent configuration.

But I'm just curious for a point of accuracy if PAK/Serial numbers are issued for LIC-CUCM-ESS orders?

I don't have an CUCM 8.0 here but in 8.5 ATA187-Ports consume 0 (zero) DLUs.

Only ATA186-Ports use 1 DLU per Device

Maybe you have a look at the License Unit Calculator (System -> Licensing -> ...)

Actually looking on CUCM, I've just realised that an ATA187 does not consume a DLU, whereas an AT186 does!

Also other devices covered by Essential don't consume DLUs.

So it would appear Cisco don't enforce DLUs/License for Essential based usage. Does this change on V9+, how would they enforce it on that version?

Hi,

ATA 186 consumes DLU. ATA 187 is counted as an essential device like 3905 where in only paper licnese is required.

you can refer the link where it shows ATA 186 consumes 2 DLU.

Starting with CUCM 9 there are no DLUs any longer.

The licenses are enforced!
