DIP (Destination IP	The destination IP address of a frame.
Address)
Dport (Destination	The destination port (application socket: for example, http-80/https-443/DNS-53)
Port)
NAT (Network Address	Any time an IP address is changed from one source IP or destination IP address to another
Translation)	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). Min-
	imum 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 (Source IP Address)	The source IP address of a frame.
SPort (Source Port)	The source port (application socket: for example, HTTP-80/HTTPS-443/DNS-53).
Tracking	In VRRP, a method to increase the priority of a virtual router and thus master designation
	(with preemption enabled). Tracking can be very valuable in an active/active configura-
	tion.
	You can track the following:
	ifs: Active IP interfaces on the Web switch (increments priority by 2 for each)
	ports: Active ports on the same VLAN (increments priority by 2 for each)
	vrs: Number of virtual routers in master mode on the switch
VIR (Virtual Interface	A VRRP address that is an IP interface address shared between two or more virtual rout-
Router)	ers.
