PoS Commands
The Packet over SONET (PoS) modules are I/O modules for the BlackDiamond switch. These modules
connect a BlackDiamond 6800 series switch to the SONET infrastructure used by metropolitan area
service providers and operators of server co-location networks. (The BlackDiamond 6800 series switch is
a chassis-based switch designed to be placed in the core of your network.)
Two key applications for the PoS modules are: interconnecting metropolitan area networks across the
SONET network infrastructure, and interconnecting server co-location network sites directly using
SONET links.
In the first application, the metropolitan area network service provider can build service network sites
in various cities, then use PoS modules in a BlackDiamond switch to connect those cities to a carrier’s
SONET infrastructure.
In the second application, operators of server co-location networks can use PoS modules in
BlackDiamond switches to create a SONET-based connection between server co-location sites. The result
is that their network is simpler to manage, and problems can be isolated and resolved more expediently.
This chapter documents the PoS command set. Some commands are new for the PoS modules; other
commands have been enhanced to support the PoS modules.
