QoS Support
•
•
•
•
•
Supports per-system option to enable flow control for best effort frames even on QoS enabled ports
Classification based on:
•
•
•
•
The precedence of the above classifications is programmable
Supports IEEE 802.3ad link aggregation
•
•
Supports module hot swap on all ports
MIB Statistics counters for all ports
Full Duplex Ethernet IEEE 802.3x Flow Control
Backpressure flow control for Half Duplex ports
Hardware auto-negotiation through MII management interface (MDIO) for Ethernet ports
Built-in reset logic triggered by system malfunction
Built-In Self Test for internal SRAM
IEEE-1149.1 (JTAG) test port
Static address filtering for source and/or destination MAC
Static MAC address not subject to aging
Secure mode freezes MAC address learning (each port may independently use this mode)
Supports port authentication (IEEE 802.1x)
Supports IEEE 802.1p/Q Quality of Service with 2 transmission priority queues (4 for uplink port), with
strict priority and/or WFQ service disciplines
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
Port based priority
VLAN Priority field in VLAN tagged frame
DS/TOS field in IP packet
UDP/TCP logical ports: 8 hard-wired and 8 programmable ports, including one programmable range
Up to 8 trunk groups, with up to 8 ports per group
Supports load sharing among trunk ports based on:
