Product manual

the 'no dscp-map <000000.111111>' function must be used.
o diff-services <000000|000001...111111> - The value of the upper
6 bits in the ToS eld.
o dscp <000000|000001...111111> - Re-maps a given inbound Differentiated
Services codepoint to the specied DSCP Policy and codepoint on
outbound.
Supported Values:
Binary formatted value from 000000 to 111111
Next Available Option:
■ dscp < 000000 | 000001 | 000010 | ... > -- Define Differentiated Services Codepoint to which to
map IP ToS.(p. 386)
device-priority
■ [no] qos device-priority IP-ADDR
Usage: [no] qos device-priority IP-ADDR [dscp <000000|000001...111111>|
priority <0-7>]
Description: Congure device-based priority. The priority can be set for
IP packets from/to a particular IP Address. The specied
priority value will be placed in the 802.1p priority eld of
outgoing tagged packets. The packets will also be placed in
the appropriate outbound priority queue. '7' means highest
priority. If 'dscp' is specied, the priority of the outgoing
packets is dened by the Differentiated Services Codepoint
mapping (see 'show qos dscp-map'). Using 'no' removes any
priority assignment for this IP address.
Next Available Options:
■ dscp < 000000 | 000001 | 000010 | ... > -- Specify DSCP policy to use. (p. 386)
■ priority < 0 | 1 | 2 | ... > -- Specify priority to use. (p. 388)
diff-services
■ qos type-of-service diff-services
In IP Differentiated Services (Diffserv) mode, IPv4 packets are classied
and given a QoS priority based on the upper 6 bits of the IP ToS
eld 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>
