How do I specify the emergency location in CDP?
- by chrish
In the LLDP-MED and Cisco Discovery Protocol whitepaper, it compares LLDP-MED and CDP. The part I am interested in is emergency location configuration. In LLDP-MED, I can specify the Emergency Line Indentification Number (ELIN) and that number will be used by some IP Phones (e.g. Aastra) when placing emergency calls.
The whitepaper states:
Location Identification Discovery
This capability is important because
it normally provides location
information from the switch to the
phone. (If the phone is configured
with location information or can
determine its location, then it may
send this information to the switch.
However, the real value is getting
this information from the switch to
the phone for phones that cannot
determine their own location.)
Location identification discovery
allows the phone to be aware of its
location-information that can be used
for location-based applications on the
phone. More importantly, this
capability can be used to provide
location information when making
emergency calls. Both Cisco Discovery
Protocol and LLDP-MED support the
transportation of location
information. However, LLDP-MED has
more supported data formats than Cisco
Discovery Protocol.
I have found the documentation on how to set the location and associate the location to the interfaces for LLDP-MED. How is this done for CDP? Is ELIN supported for CDP?
