Glossary
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).
