Patch 54266-02
C613-10417-00 Rev B
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.
