Traffic Classification
QoS Support
3 port trunking groups, one for the 2 Gigabit ports, and two groups for 10/100 ports, with up to 4 10/100
ports per group. Or 8 groups for 10/100 ports with up to 2 10/100 ports per group
Load sharing among trunked ports can be based on source MAC and/or destination MAC. The Gigabit
trunking group has one more option, based on source port
Port Mirroring to any two ports of 0-15 in managed mode or to a dedicated mirroring port in unmanaged
mode
Full set of LED signals provided by a serial interface, or 6 LED signals dedicated to Gigabit port status only
(without serial interface)
Built-in MIB statistics counters
Recognizes Simple Bandwidth Management (SBM) and Resource Reservation Potocol (RSVP) packets and
forwards to CPU
Hardware auto-negotiation through serial management interface (MDIO) for Ethernet ports
Built-in reset logic triggered by system malfunction
Built-in self test for internal and external SRAM

553 BGA package
• 4 transmission priorities for Fast Ethernet ports with 2 dropping levels
• Classification based on:
• The precedence of the above classifications is programmable
• Supports IEEE 802.1p/Q Quality of Service with 4 transmission priority queues with delay bounded, strict
• Provides 2 levels of dropping precedence with WRED mechanism
• User controls the WRED thresholds
• Buffer management: per class and per port buffer reservations
• Port-based priority: VLAN priority in a tagged frame can be overwritten by the priority of Port VLAN ID
