19. 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

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.
20. rate-limit command
This command is used to set the ingress and egress rate limit level of the
interface port(s). The working rate limit number is counted with (rate limit
level)x(rate limit unit). The rate limit unit is set by “rate-limit unit x”
command in general configuring mode (under “(config)#” prompt). And the
rate-limit level is set by this command.
rate-limit input level x command is used to specify the ingress rate-limit level
of the interface port(s). x” is the level number and its valid value is 0~31. If
x”=0, it means “no limit”.
rate-limit output level x command is used to specify the egress rate-limit level
of the interface port(s). x” is the level number and its valid value is 0~31. If
x”=0, it means “no limit”.
21. shutdown command
This command is used to disable the interface port(s).
shutdown command is used to disable the interface port(s).
no shutdown command is used to enable it.
22. spanning-tree command
