COMMAND STRUCTURE
■ [no] qos apptype < udp-port | tcp-port > -- Configure priorities for TCP/UDP services (p. 383)

■ range -- Specify range of TCP/UDP ports from [to] which to prioritize traffic. (p. 391)
■ port-num -- TCP/UDP port from [to] which to prioritize traffic. (TCP/UDP-PORT) (p. 388)
■ max-port-num -- Maximal TCP/UDP port in the range from [to] which to prioritize traffic.
(TCP/UDP-PORT) (p. 388)
■ dscp < 000000 | 000001 | 000010 | ... > -- Specify DSCP policy to use. (p. 386)
■ priority < 0 | 1 | 2 | ... > -- Specify priority to use. (p. 388)
■ [no] qos device-priority -- Configure device-based priority (IP-ADDR) (p. 385)
■ dscp < 000000 | 000001 | 000010 | ... > -- Specify DSCP policy to use. (p. 386)
■ priority < 0 | 1 | 2 | ... > -- Specify priority to use. (p. 388)
■ [no] qos dscp-map < 000000 | 000001 | 000010 | ... > -- Define mapping between a DSCP
(Differentiated-Services Codepoint) value and an 802.1p priority. (p. 386)
■ name -- Specify DSCP->priority mapping name. (p. 388)
■ name-string -- Specify DSCP->priority mapping name. (ASCII-STR) (p. 388)
■ priority < 0 | 1 | 2 | ... > -- Specify priority to use. (p. 388)
■ [no] qos protocol < IP | IPX | ARP | ... > -- Configure protocol-based priority (p. 390)
■ priority < 0 | 1 | 2 | ... > -- Specify priority to use. (p. 388)
■ qos queue-config -- Sets the number of outbound port queues that buffer the packets depending
on their 802.1p priority. (p. 390)
■ 2-queues -- Set the number of outbound port queues for all switch ports. (p. 383)
■ 4-queues -- Set the number of outbound port queues for all switch ports. (p. 383)
■ 8-queues -- Set the number of outbound port queues for all switch ports. (p. 383)
■ [no] qos type-of-service -- Configure the Type-of-Service method the device uses to prioritize IP
traffic (p. 391)
■ diff-services -- In IP Differentiated Services (Diffserv) mode, IPv4 packets are classified and
given a QoS priority based on the upper 6 bits of the IP ToS field from the packets as they enter
the switch. The assignment of Diffserv Codepoints to 802.1p priorities is done via the qos
dscp-map command. Any Diffserv Codepoint in an inbound IPv4 packet can be re-mapped to
a different codepoint (and its associated 802.1p priority) on outbound. This is done by using
the syntax: qos type-of-service diff-services <000000...111111> dscp <000000..111111> (p. 385)
■ codepoint < 000000 | 000001 | 000010 | ... > -- Configure the Type-of-Service method the
device uses to prioritize IP traffic (p. 384)
