  • Page 24: Store And Forward Switching

    ELS10-27 does not need to learn network topology, requiring less programming and conÞguration time. Store and Forward Switching As an intelligent Ethernet switch, the SmartSTACK Ethernet ELS10-27 uses store and forward switching. Store and forward switching allows the SmartSTACK Ethernet ELS10-27 to temporarily store packets until network resources, typically an unused link, are available for forwarding.

  • Page 25: Discarding Local Traffic

    Introduction This allows for complete error checking, and limits the amount of time between a device request access to the network, and permission to transmit. In addition, full store and forward switching ensures data integrity; preventing network error conditions from being generated throughout the network.

  • Page 26: Spanning Tree Algorithm

    Introduction Spanning Tree Algorithm The SmartSTACK Ethernet ELS10-27 supports the IEEE 802.1D Spanning Tree algorithm. The Spanning Tree algorithm converts multiple LANs into a Òspanning treeÓ of networks. It is used to prevent bridging loops. This standard deÞnes a logical (not physical) network conÞguration consisting of one extended LAN without active duplicate paths between spanning tree bridges.

  • Page 27: Chapter 5 Smartstack Ethernet

    ¥ The age of the entry The SmartSTACK Ethernet ELS10-27 database allows for 2048 entries. Some of these entries will be used for permanent entries needed by the switch, and temporary entries dependent on the feature set selected. The remainder will be available for user addresses.

  • Page 28: Smartstack Ethernet Els10-27 Sample Applications

    With address mirroring, a unicast MAC address and a destination port are speciÞed. Any time a valid packet is received on any port with that destination MAC address within the switch, that packet will be monitored to the destination port. If the address form of the mirror command is issued multiple times, all unicast MAC addresses selected will be mirrored.

This only applies to multi-protocol environments, such as a combination of Ethernet, FDDI, and Token Ring protocols and does not apply to the SmartSTACK Ethernet ELS10-27. 802.1Q does NOT replace 802.1D but limits the relaying of packets on the spanning tree to a subset.
