Excess-Priority is a scheme for distributing excess bandwidth. The lowest number is the highest priority
for a connection to receive excess bandwidth. If two or more connections have equal priority, the excess
bandwidth is equally distributed between them.
Explicit Rate Stamping (ERS) applies to only ABR connections.
Cell loss ratio (CLR) is currently hard-coded, so do not attempt to modify it through the Cisco WAN
Manager application or the CLI commands.

Display VC thresholds for SCT 2.
The Scaling COSB value applies to congestion in a Class of Service Buffer: if a particular buffer
becomes congested, this scaling factor determines the how quickly the rate at which cells enter the buffer
is throttled back (until the buffer is no longer congested, at which time normal rates resume).
The Scaling Log-If is a scaling factor that applies to congestion on an entire port: when the whole port
is congested, this factor determines the rate at which traffic is throttled back (until the port is no longer
congested, at which time normal rates resume).
