Hi Nikhil, You can implement a crosscall function in the L3Forwarder microace using the idl provided. Then you can call that function from the stack ace. The SDK Reference and the SDK Guide provides the necessary information on how to implement and invoke crosscall api. -- Shyamal Pandya Arizona State University Addr: 920 S Terrace Rd #102 Tempe AZ 85281 Phone: 1-480-966-1982

I need to send a packet from a Linux user application to the core component of the L3Fwdr ace. This packet will pass through the stack ace. Right now the stack ace is bound to egress ace. What is the mechanism for hooking the stack ace to some callback function in the L3Fwdr ?

Nikhil
