PCR: 40647 Module: ETHLevel: 2
When a virtual Eth interface was created over ATM, for example, using the command:
create eth=0 over=atm=0.1
and a VPN configuration was applied directly to that Eth interface, the router ran out off buffers and caused a fatal exception under heavy reception load.
This issue has been resolved: a limit has now been set so that the virtual Ethernet interfaces, like physical Eth interfaces, stop reception by dropping excess packets when the ethernet receive queue is too long or when the router is running out of buffers. The ifInDiscards counter, displayed in the output of the show eth counter command, is incremented when this happens on a virtual Eth interface.
