Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
When an emergency call is placed from a properly
configured class 3 endpoint device to an appropriate
PSAP, the country code, device type, and type/value
pairs configured on the switch port are included in the
transmission. The “type” specifiers are used by the
PSAP to identify and organize the location data
components in an understandable format for response
personnel to interpret. A civic-addr command requires
a minimum of one type/value pair, but typically
includes multiple type/value pairs as needed to
configure a complete set of data describing a given
location.
CA-TYPE: This is the first entry in a type/value pair,
and is a number defining the type of data
contained in the second entry in the type/value
pair (
CA-VALUE). Some examples of CA-TYPE
specifiers include:
•3 = city
• 6 = street (name)
•25 = building name
(Range: 0 - 255)
For a sample listing of
CA-TYPE specifiers, refer to
table 15-5 on page 15-60.
CA-VALUE: This is the second entry in a type/value
pair, and is an alphanumeric string containing
the location information corresponding to the
immediately preceding
CA-TYPE entry. Strings
are delimited by either blank spaces, single
quotes (‘ ... ‘), or double quotes (“ ... “). Each string
should represent a specific data type in a set of
unique type/value pairs comprising the
description of a location, and each string must
be preceded by a CA-TYPE number identifying the
type of data in the string.
Note: A 5300xl port allows one instance of any given CA-
TYPE. For example, if a type/value pair of 6 Atlantic (to
specify “Atlantic” as a street name) is configured on port
A5 and later another type/value pair of 6 Pacific is
configured on the same port, then Pacific replaces
Atlantic
in the civic address location configured for port A5.
