The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them.
Common Internal Spanning Tree (CIST): Identifies regions in a network and administers the CIST root bridge for the network, for each region and for each spanning tree instance in each region. It's also the default spanning tree instance of MSTP so that any VLAN which isn't a member of a particular MSTI, will be a member of the CIST.
This means that SPBV can use this traditional spanning tree for computation of the common and internal spanning tree (CIST). The CIST is the default tree used to interwork with other legacy bridges. It also serves as a fallback spanning tree if there are configuration problems with SPBV. SPBV has been designed to manage a moderate number of ...
IEEE 802.1D is the Ethernet MAC bridges standard which includes bridging, Spanning Tree Protocol and others. It is standardized by the IEEE 802.1 working group. It includes details specific to linking many of the other 802 projects including the widely deployed 802.3 (Ethernet), 802.11 (Wireless LAN) and 802.16 (WiMax) standards.
IEEE 802.1Q, often referred to as Dot1q, is the networking standard that supports virtual local area networking (VLANs) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames.
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
Within the IEEE Ethernet standards, the Link Aggregation Control Protocol (LACP) provides a method to control the bundling of several physical links together to form a single logical link. LACP allows a network device to negotiate an automatic bundling of links by sending LACP packets to their peer, a directly connected device that also ...
Unidirectional Link Detection (UDLD) is a data link layer protocol from Cisco Systems to monitor the physical configuration of cables and detect unidirectional links. UDLD complements the Spanning Tree Protocol which is used to eliminate switching loops .
