Ethernet features

Ethernet

• Ethernet ports support GE and 10GE and full duplex.
  NOTE:

  • 10GE optical ports support SFP electrical modules.
• Flow control on interfaces
• Jumbo frames
• Link aggregation
• Load balancing among links within a trunk
• Interface isolation and forwarding restrictions
• Broadcast storm suppression

Virtual Local Area Network (VLAN)

• Multiple interface types: Access, Trunk, and Hybrid
• Default VLAN

Media Access Control (MAC)

• Automatic learning and aging of MAC addresses
• Static, dynamic, and blackhole MAC address entries
• Packet filtering based on source MAC addresses
• Interface-based MAC learning limits

Address Resolution Protocol (ARP)

• Static and dynamic ARP entries
• ARP in a VLAN
• Aging of ARP entries

Ethernet loop protection

Multiple Spanning Tree Protocol (MSTP)

• Spanning Tree Protocol (STP)
• Rapid Spanning Tree Protocol (RSTP)
• MSTP
• Bridge protocol data unit (BPDU) protection, root protection, and loop protection

QoS features

Traffic classification

Traffic classification based on combination of the L2 protocol header, IP 5-tuple, outbound interface, and 802.1p priority

Traffic behavior

• Access control after traffic classification
• Traffic policing based on traffic classifiers
• Re-marking based on the traffic classification result
• Class-based packet queuing
• Association between traffic classifiers and traffic behaviors

Queue scheduling

• Priority queuing (PQ) scheduling
• Deficit round robin (DRR) scheduling
• PQ+DRR scheduling
• Weighted round robin (WRR) scheduling
• PQ+WRR scheduling

Congestion avoidance

Weighted Random Early Detection (WRED)

Rate limiting on outbound interfaces

Configuration and maintenance

Terminal service

• Configuration using command lines
• Error messages and online help in English and Chinese
• Login through console and STelnet terminals
• Send function and data communications between terminal users

File system

• Directory and file management
• File upload and download using File Transfer Protocol (FTP) and Trivial File Transfer Protocol (TFTP)

Debugging and maintenance

• Unified management of logs, alarms, and debugging information
• Electronic labels
• User operation logs
• Detailed debugging information for network fault diagnosis
• Network test tools such as tracert and ping commands
• Port mirroring and traffic mirroring

Version upgrade

• Device software loading and in-service software loading
• In-service upgrade using the basic input/output system (BIOS) menu

Security and management

System security

• Hierarchical command-line protection based on user levels, preventing unauthorized users from using commands to access switch modules
• Secure Shell (SSH)
• Access control list (ACL) filtering
• DHCP packet filtering (appending the Option 82 field)
• Defense against control packet attacks
• Defense against attacks of source address spoofing, LAND, SYN flood (TCP SYN), smurf, ping flood (ICMP echo), teardrop, and ping of death

Network management

• ICMP-based ping and tracert
• Simple Network Management Protocol Version 1/2c/3 (SNMPv1/v2c/v3)
• Standard management information base (MIB)

Serial port

RJ–45

10GE optical port

SFP+

16

This port is used to exchange data with a service network.

Each port has two indicators. The orange one is a data transmission status indicator, and the green one is a connection status indicator.

8G FC optical port

SFP+

8

This port is used to connect to a storage network.

Each port has two indicators. The orange one is a data transmission status indicator, and the green one is a connection status indicator.
