Link Aggregation
• 802.3ad support
- Number of Link Aggregation Groups (LAGs) supported: 64
- Maximum number of ports per LAG: 8
• LAG load-sharing algorithm—bridged or routed (unicast or
multicast) traffic:
- iP: S/D iP
- TcP/UDP: S/D iP, S/D Port
- Non-iP: S/D MAc
- Tagged ports support in LAG
Spanning Tree
• Spanning Tree Protocol (802.1D)
• Multiple Spanning Tree Protocol (MSTP) (802.1s)
• rapid Spanning Tree Protocol (rSTP) (802.1w)
• VSTP - VLAN Spanning Tree
• BPDU protect
• Loop protect
• root protect
Quality of Service (QoS)
• Layer 2 QoS
• Layer 3 QoS
• rate Limiting:
- ingress policing: 1 rate 2 color
- Egress shaping: per-queue, per-port
• Eight hardware queues per port
• Scheduling methods (egress): Strict priority (SP), shaped
deficit weighted round-robin (SDwrr)
• 802.1p remarking
• Layer 2-4 classification criteria: interface, MAc address,
Ethertype, 802.1p, VLAN, iP address, DScP/iP precedence, TcP/
UDP port numbers, etc.
UDP port numbers, etc.
• congestion avoidance capabilities: weighted tail drop eight
queues
