22 power-saving command
This command is used to enable the power-saving function for the interface port(s). If it is enabled and auto-
negotiation is also enabled, the interface port(s) will go to low-power mode when link down. That can reduce power
consumption of the switch. When link is detected, ports will come back to normal working state automatically.
power-saving command is used to enable the power-saving function for the interface port(s).
no power-saving command is used to disable this function on the interface port(s).
23 qos command
This command is used to set port-based priority on the interface port(s). And enable 802.1P priority, DSCP priority
on the interface port(s).
(config-if)# qos ?
dscp enable IP DSCP priority
port Port priority map
precedence enable IP precedence priority
qos dscp command is used to enable DSCP priority operation on the interface port(s). And no qos dscp command is
used to disable it.
qos precedence command is used to enable 802.1P priority operation on the interface port(s). And no qos
precedence command is used to disable it.
qos port x command is used to set port-based priority on the interface port(s). “x” is the priority queue, and its value
is 0-3 (0:Low, 1:Normal, 2:Medium, 3:High).
Note
: If DSCP priority, 802.1P priority and Port-based priority are enabled on the interface port(s) at the same time,
its decision flow is DSCP -> 802.1P -> Port-base.
