ACE 4710 upgrade to A4(2.1)

[g-georgiou]

Hi,

I am currenlty running A3(2.6) and evaluate the possibility of upgrading to A4(2.1).

The Instal & Upgrade Guide A4(2.0) mentions that A4(2.0) does not include all features of A4(1.1).

Does this apply to A4(2.1)? The Release Notes mentions a list of features merged from A4(1.1) to A4(2.1)

but does not clarify if there any features not merged.

Does anybody experienced an upgrade to A4(2.1) and are there any implications (other than the ones mentioned in the Release Notes)?

George-

You probably want to get a tac case open to be sure you don't have any SSL related issues/bugs going on here. However, my ininitial thought was either HTTP parse length is too short for the HTTP header your client may be sending.

Check "show stat http" and look for both of these:

"Max parselen errors" and "Static parse errors"

If you see any, then create an http parameter map and apply it to the class map under the policymap multimatch.

i.e.

parameter-map type http FixMe

set header-maxparse-length 8192

Policy-map multi-match PMM

  Class VIP

   loadbalance vip inservice

   loadbalance policy LBPM

   appl-parameter http advanced-options FixMe
