Traffic Management and QoS

• IEEE 802.1p
• 8 egress queues per port for different types of traffic
• WFQ (Weighted Fair Queue) scheduling for different prioritization of packets.
• Strict priority queuing for highest priority packets to get best service
• IEEE 802.1Q tag-based and port-based VLAN
• 256 static VLAN, up to 4K dynamic VLAN

• Supports IGMP snooping.
• Congestion control on all ports

Rate Limiting

• Allow bandwidth to be shaped in steps at 64Kbps
• Rate limiting based on combination of L2/L3/L4 fields using ACL

Link Aggregation

• IEEE 802.3ad compliant.
• Support LACP, static and dynamic link aggregation.
• Up to 6 aggregation groups.
• 8 ports per group randomly selected.

Redundancy for Fault Backup

• IEEE802.1w Rapid Spanning Tree Protocol (RSTP) provides rapid convergence of spanning tree independent of spanning-tree timer
• Supports ZyXEL Backup Power System (BPS) that provides internal power source redundancy, improve fault tolerance

User Security and Authentication

• MAC filtering per port secures access to each port
• Specific MAC forwarding per port: only specified MAC addresses can access the network (port lock).
• Limit the number of MAC address per port.
• 802.1x port-based security, prevent unauthorized client access to the network.
• Private VLAN provides security and isolation between ports on a switch, ensures that users can not snoop on each other’s traffic

Network Administration Security

• User name/password required for web/telnet/local console administrators
• Two level security by specific SNMP read/write community
• SSH provides network security by encrypting administration traffic

Network Management
