D - Glossary The following networking and teaming terms are used in this document: 802.1D Refers to the IEEE 802.1D specification. This is the original Spanning Tree specification. 802.3ad Dynamic Refers to the IEEE 802.3ad specification. This specification provides for manual and automatic (dynamic) port grouping for fault tolerance and load balancing between two network devices. Active Path An advanced redundancy mechanism used by HP Integrity Network Adapter Teaming that allows the team to monitor per-teamed port connectivity with an external device (Echo Node). ALB (Adaptive Refer to Transmit Load Balancing (TLB). Load Balancing) ARP Address Resolution Protocol. A Layer 2 protocol used to determine a MAC address from an IP address. A network device broadcasts an ARP request to ask for the MAC address for a given IP address. The network device with the given IP address responds back with an ARP reply providing its MAC address to the original requester. BIA Burned In Address. The Layer 2 address that is permanently assigned to a piece of hardware by the vendor. Referred to as a MAC address. Can be overridden by a Locally Administered Address (LAA). Bit The smallest value in binary. A bit is a single value that's equal to either 1 or 0. The collection of 8 bits is called a byte. BPDU Bridge Protocol Data Unit. A special configuration frame used by the Spanning Tree Protocol. Broadcast domain Set of all devices that will receive Layer 2 broadcast frames originating from any device within the set. Broadcast domains are typically bounded by routers because routers do not typically forward Layer 2 broadcast frames. Byte Eight bits Collision domain A single Ethernet network segment in which there will be a collision if two computers attached to the system transmit simultaneously. Component Pack An HP-specific term used for a self extractable package for installing drivers on a server. The file name syntax is CPnnnnn.exe. Degraded A team or teamed port status that indicates it is still in use but not completely whole. Dual Channel A special team type used by HP Integrity Network Adapter Teaming that allows for NIC port redundancy, switch redundancy, outbound load balancing, and receive load balancing all on the same team. Echo Node A special device used by the Active Path mechanism. This is a device that is simply "designated" for use. The device doesn't need any special software or configuration other than an IP address. Echo Node probe A special frame used by Active Path to validate connectivity with the Echo Node. Failed A team or teamed port status that indicates it is not in use because of a failure important enough to cause it to be disabled. Failover A term used to describe any event that causes the role of Primary port in a team to change from one teamed port to another. Fast Path An advanced redundancy mechanism used by HP Integrity Network Adapter Teaming that allows the team to monitor per-teamed port connectivity with the Spanning Tree root switch and monitor network bandwidth. FEC Fast EtherChannel. A method of load balancing that both transmits and receives traffic across multiple Fast Ethernet connections (100 Mbps) between two devices. Developed by Cisco Systems.
