Hi Chris, Jeff,
yesterday we upgraded our 7507/RSP4 from 12.0(10)S1 to 12.0(13)S. We
have two PA-A3-OC3-MM (HWrev 2.0) interfaces, both sitting in a
dedicated VIP2-50, each with 128DRAM/8SRAM, in total ~30 subinterfaces
and ~40 PVCs configured, one PA-A3 is peaking up to 60Mbps the other one
to 120Mbps. Still knocking on wood, but it's working so far. Last
weekend colleagues of mine failed with a similar upgrade (12.0(13)
mainstream not S) and a PA-A3 w HWrev 1.0.
So Jeff's problems indeed seem to be related to the HWrev of the PA-A3 !
Yet, just one flaw identified in our config with 12.0(13)S:
"ip accounting mac-address input" does no longer work (on a PA-FE in
our case), config command disappeared and can not be re-entered.
However, we have not yet turned on "dCEF" just plain CEF (and 70% CPU
:-(, probably we turn on dCEF tomorrow. Will keep you informed ...
Best wishes
CP
