Cisco ASR 1002-X - Recommended stable IOS release for ISG feature?

[Kourilenko Konstantin]

Hello ALL.

I use Cisco ASR 1002-X for termination of users (ISG feature, IP authorisation without NAT).

Now I use IOS: asr1002x-universal.03.11.00.S.154-1.S-std.SPA.bin.

After 10 months from the last reload I see warning and error in to log messages.

%CPPOSLIB-3-ERROR_NOTIFY: SIP0: cpp_cp:  cpp_cp encountered an error -Traceback= ...

%CPP_FM_TCAM_WARNING: SIP0: cpp_sp:  TCAM limit exceeded: HW TCAM cannot hold Class group ess-tc-cg:1459765883.  Use SW TCAM instead.

I think that reload a Cisco will solve this problem for a certain time.

But I want to solve this problem further.

What version of IOS at the moment is considered the stablest?

On the Cisco WEB-site I see two the recommended IOS with Extendet-Support timeline.

Suggested

3.16.5S(ED) 

3.13.6aS(MD) 

Many Thanks.
