Converged Network Adapter. A device used for I/O consolidation such as that in 
Converged Enhanced Ethernet (CEE) environments implementing Fibre Channel over 
Ethernet (FCoE). The CNA performs the duties of both a Network Interface Card 
(NIC) for Local Area Networks (LANs) and a Host Bus Adapter (HBA) for Storage 
Area Networks (SANs).

The destination IP address of a frame.

The destination port (application socket: for example, http-80/https-443/DNS-53)

Host Bus Adapter. An adapter or card that interfaces with device drivers in the host 
operating system and the storage target in a Storage Area Network (SAN). It is 
equivalent to a Network Interface Controller (NIC) from a Local Area Network 
(LAN).

Network Address Translation. Any time an IP address is changed from one source IP 
or destination IP address to another address, network address translation can be said to 
have taken place. In general, half NAT is when the destination IP or source IP address 
is changed from one address to another. Full NAT is when both addresses are changed 
from one address to another. No NAT is when neither source nor destination IP 
addresses are translated. 

In VRRP, preemption will cause a Virtual Router that has a lower priority to go into 
backup should a peer Virtual Router start advertising with a higher priority.

In VRRP, the value given to a Virtual Router to determine its ranking with its peer(s). 
Minimum value is 1 and maximum value is 254. Default is 100. A higher number will 
win out for master designation.

The protocol of a frame. Can be any value represented by a 8-bit value in the IP header 
adherent to the IP specification (for example, TCP, UDP, OSPF, ICMP, and so on.)

The source IP address of a frame.

The source port (application socket: for example, HTTP-80/HTTPS-443/DNS-53).
