Port Status and Basic Configuration
QoS Pass-Through Mode on the Series 2800 Switches
This command can be enabled and disabled only from the switch's CLI. QoS
passthrough mode cannot be enabled or disabled through either the switch's
menu or web browser interfaces.
Once enabled, this feature adds
qos-passthrough-mode to the switch’s startup­
config file. For example, in an otherwise default configuration, executing show
config lists the startup-config file (with QoS pass-through mode enabled) as
follows:
Indicates QoS Pass-
Through mode enabled.
