Classifiers and Hardware Filters

On AT-8948, AT-9900, AT-9900s, and x900 series switches, the switching hardware has a limit of 16 bytes to use for matching on incoming packets.

EPSR creates a hardware filter that uses 2 bytes for VLAN identification (since version

291-04). This means that you have to design your network carefully when using EPSR with DHCP snooping, QoS, or other hardware filters.

For example:

•DHCP snooping uses 5 bytes to match on the source and destination UDP ports and the protocol field. With EPSR and DHCP snooping both enabled, 7 out of the 16 bytes are used.

•IP addresses use 4 bytes. So if you configured EPSR, DHCP snooping, and a QoS policy that classified on source IP address, then 11 of the 16 bytes would be used.
