ECURITY
The Network Power Switch can be configured to keep unauthorized IP addresses
from getting Telnet access to the Switch. This allows you to grant Telnet access to
only a specific group of IP addresses, or block a particular IP address from gaining
access. In the default state, the Network Power Switch accepts incoming IP
connections from all hosts. To configure the IP Security feature:
1. Access the Network Parameters menu as described in
Section 4.6
. Note that
the Network Parameters menu is not available in User Mode.
2. When the Network Parameters menu appears, type
4
and press
[Enter]
to
access the IP Security menu.
3. The IP Security menu lists five IP Security “masks” along with the selected
permit/deny action for each mask.
a) Each Security Mask prompt is used to define a specific IP address or
range of IP addresses. Each Mask Action prompt is used to define the
permit/deny action for the corresponding Mask.
b) Masks are listed in order of ascending priority; Mask 1 has the lowest
priority, Mask 5 has the highest priority.
c) Masks have a cumulative effect; high priority masks supersede the effect
of lower priority masks.
d) Each IP Address consists of a series of four eight-bit numbers. The
number 255 is used as a wild card.
