or datacom rack
LEDs
• System LEDs that indicate status
Airflow
• Front-to-back or back-to-front cooling

Software
Security
• RADIUS
• TACACS+
• Access control lists (ACLs): Allow and deny
• SSH v1, v2
• Secure interface login and password
• Local proxy Address Resolution Protocol (ARP)
• Static ARP support
Layer 2 Switching
• Maximum number of MAC addresses in hardware: 32,000*
• Jumbo frames: 9,216 bytes
• Number of VLANs: 4,096
• Port-based VLAN
• 4,096 VLAN IDs supported
• Routed VLAN interface (RVI)
* MAC address table uses a hash-based scheme to program entries; therefore, some entries
may not be programmed due to hash index collision.

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
• RSTP and VSTP running concurrently
• 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)
• EZQoS
• CoS on L3 VLAN
• Per interface rewrite
• Per interface classification
• Policer mark down action
• Remarking of bridged packets
• 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.
• Congestion avoidance capabilities: Weighted tail drop eight
queues
