[cisco-bba] Cisco 10008ESR PRE2 - "ip tcp adjust-mss <value>" support?

[A]

Hi list,
I've recently been advised by Cisco that the "ip tcp adjust-mss <value>" 
command that we've previously used to great affect on our 7301s for working 
around fragmentation and MTU issues in an LNS environment is not supported 
on the Cisco 10008ESR-PRE2 platform that we had planned on eventually 
upgrading to.

Our research has come up with a few (less attractive) possiblities for 
working around these issues (some of which are documented here:
http://www.cisco.com/en/US/tech/tk801/tk703/technologies_tech_note09186a0080094c4f.shtml), 
but due to the large number of clients/cpe that don't perform lcp 
renegotiation correctly and the issues with pmtu discovery none of these 
workarounds seems to be ideal when compared to having the LNS adjust the MSS 
of TCP connections.

Have other SP's utilising the 10K platform run into this and how are you 
working around these types of issues?

Any advice would be greatly appreciated - Thank you.

Regards,
Chris
