Hi, > Lastest one running SXH1. No problems so far with FWSM, ACE and 6748s. we've got a 12.2(33)SXH3 box up and alive now - so far so much better than SXH2 (and 2b) but we've yet to drive packets through in anger. certainly looks like we might be SXH'd by the new year (but dont quote me on that! ;-) ) alan
