MPLS DS-TE IETF and MAM/RDM selection on Cisco IOS platforms

[GIANRICO FICHERA]

I read that in IOS 12.2(33)SRB-C-D-E there are new CLI commands to include the IETF DS-TE.
In this way we can use the MAM or RDM model for MPLS-TE in IOS using the new command "mpls traffic-eng ds-te bc-model [rdm | mam]"

I'm unable to find this command for release 15.1 or 15.2 of IOS software. It seems to me that this is available only in some IOS platforms (like 7600?) and only for 12.2(33)SR releases but I cannot find a confirmation of this.  The question is if there is a full support for IETF DS-TE with IOS and for what kind of platforms.

Thankyou

I think I found the answer by myself. DS-TE with RDM and MAM are supported by the IOS "S" release (service provider) and for the platforms 7200/7300/7600 and ASR901. The latest release is 15.3S.
