Features

Quality of Service (QoS)
- Traffic policing: supports Committed Access Rate (CAR) and line rate

Management
- Industry-standard CLI with a hierarchical structure: reduces training time and expenses, and increases productivity in multivendor installations

Connectivity
- High-density port connectivity: provides up to 4 interface module slots and up to 18 Fast Ethernet ports

Performance
- Powerful encryption capacity: includes embedded hardware encryption accelerator to improve encryption performance

Resiliency and high availability
- Backup Center: acts as a part of the management and backup function to provide backup for device interfaces; delivers reliability by switching traffic over to a backup interface when the primary one fails

Layer 2 switching
- Spanning Tree: fully supports standard IEEE 802.1D Spanning Tree Protocol, IEEE 802.1w Rapid Spanning Tree Protocol for faster convergence, and IEEE 802.1s Multiple Spanning Tree Protocol

Layer 3 services
- Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a Layer 2 network
