If an adapter is operating in normal mode, it will drop this frame, and the IP stack never sees or responds to it. If the adapter is in promiscuous mode, the frame will be passed on, and the IP stack on the machine (to which a MAC address has no meaning) will respond as it would to any other ping. [6]
A network interface controller (NIC, also known as a network interface card, [3] network adapter, LAN adapter and physical network interface [4]) is a computer hardware component that connects a computer to a computer network. [5] Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus.
QLogic offers CNAs via their QLogic 8200 & 8300 series Converged Network Adapters. They offer single and dual port PCI cards with copper or optical fibre interfaces. [4] QLogic CNAs are available under the QLogic brandname and as OEM cards. The QME CNA and drivers were supported by Citrix, NetApp, EMC and IBM. [5]
The port will not send out DTP frames or be affected by any incoming DTP frames. If you want to set a trunk between two switches when DTP is disabled, you must manually configure trunking using the (switchport mode trunk) command on both sides. The configured switch port mode setting is referred to as the port's trunking administrative mode.
Mapping between Fibre Channel N_port IDs (aka FCIDs) and Ethernet MAC addresses. "Converged" network adapter. Computers can connect to FCoE with converged network adapters (CNAs), which contain both Fibre Channel host bus adapter (HBA) and Ethernet network interface controller (NIC) functionality on the same physical card. CNAs have one or more ...
A bypass switch (or bypass TAP) is a hardware device that provides a fail-safe access port for an in-line active security appliance such as an intrusion prevention system (IPS), next generation firewall (NGFW), etc. Active, in-line security appliances are single points of failure in live computer networks because if the appliance loses power, experiences a software failure, or is taken off ...
Autonegotiation is a signaling mechanism and procedure used by Ethernet over twisted pair by which two connected devices choose common transmission parameters, such as speed, duplex mode, and flow control. In this process, the connected devices first share their capabilities regarding these parameters and then choose the highest-performance ...
TUN, namely network TUNnel, simulates a network layer device and operates in layer 3 carrying IP packets. TAP, namely network TAP, simulates a link layer device and operates in layer 2 carrying Ethernet frames. TUN is used with routing. TAP can be used to create a user space network bridge. [2]
