Lease
The amount of time that a DHCP client can keep the configuration information
that it was given by a DHCP server. When this time has expired the DHCP client
must again ask for configuration information.
Limit
A definition to specify the maximum average number of matches to allow during
the defined time frame. This parameter can take the form of X/s, X/m, X/h, or
X/d where X is the number of packets and s=seconds, m=minute, h=hour, and
d=hour. Traffic less than the limit activates the corresponding action. Traffic flow
greater than this rate causes the corresponding filtering action to be skipped for
all exceeding data packets UNLESS you specify burst sizes.
This is a filtering option where other types of tags can be used to identify types of
data along with a limited throughput and actions such as dropping or rejecting can
be specified.

123456789ABC, or 123456–789ABC. The first 6 digits is the identifying code of
the manufacturer of the device.
Metric
The number of routers between one IP address and another. This field allows you
to keep track of and manage routes according to the distance between any two
computers. Note: this is a manually entered field and will not be computed for
you.
