CNA

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).

 

 

DIP

The destination IP address of a frame.

 

 

Dport

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

 

 

HBA

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).

 

 

NAT

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.

 

 

Preemption

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.

 

 

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.

 

 

Proto (Protocol)

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.)

 

 

SIP

The source IP address of a frame.

 

 

SPort

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