    Chapter 1 | Introduction Description of Software Features Description of Software Features The switch provides a wide range of advanced performance enhancing features. Flow control eliminates the loss of packets due to bottlenecks caused by port saturation. Storm suppression prevents broadcast, multicast, and unknown unicast traffic storms from engulfing the network.
  • Page 50 Chapter 1 | Introduction Description of Software Features server located in a different network. And DHCP Relay Option 82 controls the processing of Option 82 information in DHCP request packets relayed by this device. Port Configuration You can manually configure the speed, duplex mode, and flow control used on specific ports, or use auto-negotiation to detect the connection settings used by the attached device.
  • Page 51 Chapter 1 | Introduction Description of Software Features source IP/MAC address pairs based on static entries or entries stored in the DHCP Snooping table. IEEE 802.1D Bridge The switch supports IEEE 802.1D transparent bridging. The address table facilitates data switching by learning addresses, and then filtering or forwarding traffic based on this information.
  • Page 52 Chapter 1 | Introduction Description of Software Features Virtual LANs The switch supports up to 4094 VLANs. A Virtual LAN is a collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network. The switch supports tagged VLANs based on the IEEE 802.1Q standard.

  • Page 53: Ip Routing

    Chapter 1 | Introduction Description of Software Features Quality of Service Differentiated Services (DiffServ) provides policy-based management mechanisms used for prioritizing network resources to meet the requirements of specific traffic types on a per-hop basis. Each packet is classified upon entry into the network based on access lists, IP Precedence or DSCP values, or VLAN lists.

    Chapter 1 | Introduction Description of Software Features Policy-based Routing for BGP – The next-hop behavior for ingress IP traffic can be determined based on matching criteria. Equal-cost Multipath When multiple paths to the same destination and with the same path cost are Load Balancing found in the routing table, the Equal-cost Multipath (ECMP) algorithm first checks if the cost is lower than that of any other routing entries.

  • Page 811: Glossary

    Glossary Access Control List. ACLs can limit network traffic and restrict access to certain users or devices by checking each packet for certain IP or MAC (i.e., Layer 2) information. Address Resolution Protocol converts between IP addresses and MAC (hardware) addresses. ARP is used to locate the MAC address corresponding to a given IP address.
  • Page 812 Glossary DiffServ Differentiated Services provides quality of service on large networks by employing a well- defined set of building blocks from which a variety of aggregate forwarding behaviors may be built. Each packet carries information (DS byte) used by each hop to give it a particular forwarding treatment, or per-hop behavior, at each network node.
  • Page 813 Glossary ICMP Internet Control Message Protocol is a network layer protocol that reports errors in processing IP packets. ICMP is also used by routers to feed back information about better routing choices. IEEE 802.1D Specifies a general method for the operation of MAC bridges, including the Spanning Tree Protocol.
  • Page 814 Glossary IGMP Query On each subnetwork, one IGMP-capable device will act as the querier — that is, the device that asks all hosts to report on the IP multicast groups they wish to join or to which they already belong. The elected querier will be the device with the lowest IP address in the subnetwork.
  • Page 815 Glossary Management Information Base. An acronym for Management Information Base. It is a set of database objects that contains information about a specific device. Multicast Router Discovery is a A protocol used by IGMP snooping and multicast routing devices to discover which interfaces are attached to multicast routers. This process allows IGMP-enabled devices to determine where to send multicast source and group membership messages.
  • Page 816 Glossary Port Trunk Defines a network link aggregation and trunking method which specifies how to create a single high-speed logical link that combines several lower-speed physical links. QinQ QinQ tunneling is designed for service providers carrying traffic for multiple customers across their networks.
  • Page 817 Glossary Secure Shell is a secure replacement for remote access functions, including Telnet. SSH can authenticate users with a cryptographic key, and encrypt data connections between management clients and the switch. Spanning Tree Algorithm is a technology that checks your network for any loops. A loop can often occur in complicated or backup linked network systems.
  • Page 818 Glossary XModem A protocol used to transfer files between devices. Data is grouped in 128-byte blocks and error-corrected. – 812 –...

    Chapter 1 | Initial Switch Configuration Stack Operations Stack Operations Up to eight switches can be stacked together as described in the Installation Guide. One unit in the stack acts as the Master for configuration tasks and firmware upgrade. All of the other units function in Slave mode, but can automatically take over management of the stack if the Master unit fails.
  • Page 900 Chapter 1 | Initial Switch Configuration Stack Operations Selecting the Once the Master unit finishes booting up, it continues to synchronize configuration information to all of the Slave units in the stack. If the Master unit fails or is powered Backup Unit off, a new master unit will be selected based on the election rules described in the preceding section.
  • Page 901 Chapter 1 | Initial Switch Configuration Stack Operations failover events, you should include port members on several units within the primary VLAN used for stack management. Resilient Configuration If a unit in the stack fails, the unit numbers will not change. This means that when you replace a unit in the stack, the original configuration for the failed unit will be restored to the replacement unit.

    Enabling SNMP Management Access The switch can be configured to accept management commands from Simple Network Management Protocol (SNMP) applications such as Edge-Core ECView Pro. You can configure the switch to respond to SNMP requests or generate SNMP traps. When SNMP management stations send requests to the switch (either to return information or to set a parameter), the switch provides the requested data or sets the specified parameter.
