IEEE 802.1w | An IEEE standard for the Rapid Spanning Tree Protocol (RSTP) which is |
| designed to supersede IEEE 802.1D. RSTP provides considerably faster |
| convergence for topology changes. |
IEEE 802.3 | Defines carrier sense multiple access with collision detection (CSMA/CD) |
| access method and physical layer specifications. |
IEEE 802.3ab | Defines CSMA/CD access method and physical layer specifications for |
|
|
IEEE 802.3ac | Defines frame extensions for VLAN tagging. |
IEEE 802.3u | Defines CSMA/CD access method and physical layer specifications for |
|
|
IEEE 802.3x | Defines Ethernet frame start/stop requests and timers used for flow control on |
|
|
IEEE 802.3z | Defines CSMA/CD access method and physical layer specifications for |
| 1000BASE Gigabit Ethernet. |
IGMP Snooping | Listening to IGMP Query and IGMP Report packets transferred between IP |
| Multicast Routers and IP Multicast host groups to identify IP Multicast group |
| members. |
Internet Control |
|
Message Protocol |
|
(ICMP) | Commonly used to send echo messages (Ping) for monitoring purposes. |
Internet Group |
|
Management Protocol |
|
(IGMP) | A protocol through which hosts can register with their local router for |
| multicast services. If there is more than one multicast router on a given |
| subnetwork, one of the routers is made the “querier” and assumes |
| responsibility for keeping track of group membership. |
Management of the network from a station attached directly to the network. | |
IP Multicast Filtering | A process whereby this switch can pass multicast traffic along to participating |
| hosts. |
LAN Segment | Separate LAN or collision domain. |
LED | Light emitting diode used for monitoring a device or network condition. |
Link Segment | Length of |
| and a PC. |
Local Area Network |
|
(LAN) | A group of interconnected computer and support devices. |
