• NIC + HBA = CNA

• Nexus 1000v
• Virtual Ethernet Module (VEM) - like virtual SW
• Virtual Supervisor Module (VSM) - like vCenter

• Virtual Port Channel (vPC) - allows redundant uplink access while the the redundant upstream devices appear as a single logical device to the access host. Support load balance in addition to redundancy.

• Overlay Transport Virtualization (OTV) - allows MAC transport LAN extension to other enterprise sites. Based on frame tunneling inside overlay IP packet. Use IP multicast for optimal forwarding. "MACinIP".

• Cisco FabricPath - Implement IS-IS routing principle in L2 domain, thus removing the need of STP, and offer load-balancing over parallel path.

• Locator/ ID Separation Protocol (LISP) - provides mobile access based on mapping a local address to globally reachable address.

• TrustSec - data link layer cryptography, provides protection for packet by encrypting packet on egress and decrypting on ingress at the device. Whinin device itself its in plain text, allowing to continue performing all packet inspection functions. 

• SGACL - Security Group Access Control List
• N-Port ID Virtualization (NPID) - provides a means to assign multiple FCIDs to a single N-Port. (NPIV allows multiple applications to share the same HBA).
• N-Port Virtualization - Extension to NPIV. Allows to blade switch or ToR fabric device to behave as an NPIV-based HBA to the core FC switch.
• Cisco Fabric Extenders Link (FEX-Link) (VN-TAG)
• Virtual Device Contexts (VDC)
• Ternary Content Addressable Memory (TCAM)
• Link Layer Discovery Protocol (LLDP)
• Adapter FEX (VM-FEX) - divide a single physical link into multiple virtuals links or channels. Each channel has unique channel number, and its scope is limited to the physical link.
• Fabric Extenders (FEX)
• FEX Deployment:
1. Straight-through FEX using static pinning
2. Straight-through FEX using dynamic pinning
3. Active-Active FEX using vPC.
• Private VLAN (PVLAN)

• Rapid Per VLAN STP (Rapid PVST+)
• Multiple Spanning Tree Protocol 802.1s (MST)
• Fibre Channel

• Fibre Channel Port

• Fibre Channel Registration

• Fibre Channel over Ethernet (FCoE):

• Data Center Bridging (DCB) addressed the QoS related challenges of FC deployment over classical Ethernet.
• Priority Flow Control (PFC) this is one of the 802.1bb standard providing lossless delivery for selected classes of service. (PAUSE frame).
• Enhanced Transmission Selection (ETS) this is 802.1Qaz standard providing bandwidth management and priority selection. Enables intelligent sharing of bandwidth.
• Quantized Congestion Notification (QCN) this is the 802.1Qan standard providing congestion awareness and avoidance. This is an optimal standard that vendor can choose to implement.
• Data Center  Bridging Exchange (DCBX) this is the 802.1Qaz standard. It provides a protocol for exchanging parameters between DCB-capable devices and taking advantage of function that are provided by the Link Layer Discovery Protocol (LLDP)
• DCBX is an extension of LLDP.
•
