Are ACL supported on all linecards?

I know that there are some problems with access-lists on GSR linecards. There are some problems on engine 2 linecards (in the FAQ) - but what about ACLs on engine 0 linecards (I need an acls on a STM4 card engine 0)? Does it work and how strongly will the performance suffer from that?

Re: Are ACL supported on all linecards?

E0 linecard with the Salsa4 ASIC (also called E0.5) and E1 linecardswith the Salsa4 ASIC can do ACL processing in hardware as it does route lookup. Without Salsa, the performance degradation can drop from 650Kpps to as low as 32Kpps. Salsa ACLs are enabled with the access-list hardware salsa configuration command.

Confirm that you have a Salsa4 ASIC on your E0 or E1 linecard with the command ?exec slot x show controller l3 | include ASIC?. If the output shows Revision number(Rev) >= 4, then the linecard has Salsa4 ASIC and can do Salsa ACL if it is configured.
