Features and specifications

The G7028 switch has the following features and specifications:

• Form factor: 1U rack mount switch
• Ports:
  • A total of 24 10/100/1000 Mb Ethernet ports with RJ-45 connectors.
  • Four ports for 1 Gb or 10 Gb Ethernet SFP/SFP+ transceivers (support for 1000BASE-SX, 1000BASE-LX, 1000BASE-T, 10GBASE-SR, or 10GBASE-LR) or SFP+ direct-attach copper (DAC) cables. SFP/SFP+ modules or DAC cables are not included and must be purchased separately (for more information, see Table 3).
  • One Ethernet port (RJ-45 connector) for out of band (OOB) management.
  • One RS-232 serial port (RJ-45 connector) that provides another means to configure the switch module.
  • One USB port for mass storage devices.
• Scalability and performance:
  • 10 Gb Ethernet ports for maximum network bandwidth
  • Autosensing 10/1000/1000 Gigabit Ethernet ports for bandwidth optimization
  • Non-blocking architecture with wire-speed forwarding of traffic; up to 128 Gbps of full duplex switching throughput
  • Up to 96 Million packets per second (Mpps) with switching latency of 3.3 microseconds
  • Media access control (MAC) address learning: Automatic update, support of up to 8,000 MAC addresses
  • Static and LACP (IEEE 802.3ad) link aggregation
  • Support for jumbo frames (up to 12,288 bytes)
  • Broadcast/multicast storm control
  • IGMP snooping for limit flooding of IP multicast traffic
  • IGMP filtering to control multicast traffic for hosts participating in multicast groups
  • Configurable traffic distribution schemes over trunk links based on source/destination IP or MAC addresses, or both
  • Fast port forwarding for rapid STP convergence
• Availability and redundancy:
  • IEEE 802.1D STP for providing L2 redundancy
  • IEEE 802.1s Multiple STP (MSTP) for topology optimization, up to 32 STP instances are supported by single switch
  • IEEE 802.1w Rapid STP (RSTP) (provides rapid STP convergence for critical delay-sensitive traffic such as voice or video)
  • Per-VLAN Rapid STP (PVRST) enhancements
  • Layer 2 Trunk Failover to support active/standby configurations of network adapter teaming on compute nodes
  • Hot Links provides basic link redundancy with fast recovery for network topologies that require Spanning Tree to be turned off
• VLAN support:
  • Port-based and protocol-based VLANs
  • Up to 4095 VLANs supported per switch (512 active VLANs), with VLAN numbers 1 - 4095 (4095 is used for management connection only)
  • 802.1Q VLAN tagging support on all ports
  • 802.1x with Dynamic VLAN assignment
  • Private VLANs
• Virtualization: Virtual Link Aggregation support
• Security:
  • VLAN-based, MAC-based, and IP-based access control lists (ACLs)
  • 802.1x port-based authentication
  • Multiple user IDs and passwords
  • User access control
  • Radius, TACACS+ and LDAP authentication and authorization
• Quality of Service (QoS):
  • Support for IEEE 802.1p, IP ToS/DSCP, and ACL-based (MAC/IP source and destination addresses, VLANs) traffic classification and processing
  • Traffic shaping and re-marking based on defined policies
  • Eight priority queues per port for processing qualified traffic
  • Weighted random early detection with explicit congestion notification (WRED/ECN)
  • CPU priority policies (CoPP)
  • IPv4/IPv6 ACL metering
• IP v4 Layer 3 functions:
  • Host management
  • IP filtering with ACLs
  • Support for DHCP client
  • Support for IGMP snooping and IGMP relay
• IP v6 Layer 3 functions:
  • IPv6 host management
  • IPv6 filtering with ACLs
• Manageability:
  • Industry-standard CLI (isCLI)
  • Simple Network Management Protocol (SNMP V1 and V3)
  • HTTP/HTTPS browser GUI
  • Telnet interface for CLI
  • SSH and SSH v2
  • Secure Copy (SCP)
  • Serial interface for CLI
  • Firmware image update (TFTP and FTP)
• Monitoring:
  • Switch LEDs for port status and switch module status indication
  • Remote Monitoring (RMON) agent to collect statistics and proactively monitor switch performance
  • Port mirroring for analyzing network traffic passing through the switch
  • Change tracking and remote logging with the syslog feature
