Communication Protocol Options (3 of 3)

Communication Port Subnet Mask

Possible Settings: 000.000.000.000 – 255.255.255.255, Clear
Default Setting: 000.000.000.000

Specifies the subnet mask needed to access the unit when the port is configured as a
network communication link. The subnet mask is only in effect when the Communication
Port Use configuration option is set to Net Link (see

Table 5-10

000.000.000.000 – 255.255.255.255 – Shows the subnet mask for the node, which you
can view or edit.

Clear – Clears the subnet mask for the communication port and fills the address with
zeros. When the node subnet mask is all zeros (i.e., 000.000.000.000), the IP protocol
creates a default subnet mask based on the class of the IP address:
Class A: 255.000.000.000, Class B: 255.255.000.000, or Class C: 255.255.255.000.

Communication Port Link Protocol

Possible Settings: PPP, SLIP
Default Setting: PPP

Specifies the link layer protocol to use when the communication port is configured as a
network communication link.

PPP – Point-to-Point Protocol.

SLIP – Serial Line IP Protocol.

This protocol is only in effect when the Communication Port Use configuration
option is set to Net Link (see

Table 5-10

Alternate Communication Port IP Address

Possible Settings: 000.000.000.000 – 223.255.255.255, Clear
Default Setting: 000.000.000.000

Specifies the alternate IP address for the communication port. The Alternate IP Address
is used when a call attempt does not complete on the primary alarm/trap telephone
number contained in the Alarm directory and the alternate dial-out directory is used to
try another telephone number.

000.000.000.000 – 223.255.255.255 – Shows the communication port IP address,
which you can view or edit. The first digit (i.e.,

xxx.255.255.255) cannot be 0 or 127, or

greater than 223. However, 000 is valid, representing a null address.

Clear – Clears the alternate IP address for the communication port and fills the address
with zeros (i.e., 000.000.000.000).

Alternate Communication Port Subnet Mask

Possible Settings: 000.000.000.000 – 255.255.255.255, clear
Default Setting: 000.000.000.000

Specifies the alternate subnet mask needed for the communication port. The alternate
subnet mask is used when a call attempt does not complete on the primary alarm/trap
telephone number contained in the Alarm directory and the alternate dial-out directory is
used to try another telephone number.

000.000.000.000 – 255.255.255.255 – View or edit the alternate subnet mask for the
node.

Clear – Clears the alternate subnet mask for the communication port and fills the
address with zeros (i.e., 000.000.000.000). When the alternate subnet mask is all zeros,
the IP protocol creates a default subnet mask based on the class of the IP address:
Class A: 255.000.000.000, Class B: 255.255.000.000, or Class C: 255.255.255.000.
