Cpu Queues - Alcatel-Lucent 7210 SAS M OS Quality Of Service Manual

CPU Queues

The packets that are destined to the CPU are prioritized based on the application. Some of the
applications that are prioritized are Layer 2 data packets (copy of which is sent to CPU for MAC
learning), EFM, CFM, STP, LACP, OSPF, IS-IS, RSVP, TLDP, etc.
The packets destined to the CPU are classified internally and are put into the correct queue. These
packets are rate-limited to prevent DoS attacks. The software programs the classification entries to
identify these packets and assigns appropriate bandwidth and priority to them. It is not
configurable by the user.
