Quality of Service (QoS): Managing Bandwidth More Effectively Using QoS Classifiers To Configure Quality of Service for Outbound Traffic . Syntax: qos type-of-service diff-services Enables ToS diff-services. Syntax: qos type-of-service diff-services < current-codepoint > dscp < new-codepoint > Configures the switch to select an incoming IP packet carrying the and then use the to assign a new, previously configured DSCP policy to the packet. The policy overwrites the with the < new-codepoint > and assigns the 802.1p priority specified by the policy. (Use the qos dscp-map command to define the priority for the DSCPs-page 5-51.) Syntax: no qos type-of-service Disables all ToS classifier operation. Current ToS DSCP policies and priorities remain in the configuration and will become available if you re-enable ToS diff-services. Syntax: no qos type-of-service [diff-services < codepoint >] Deletes the DSCP policy assigned to the < codepoint > and returns the < codepoint > to the 802.1p priority setting it had before the DSCP policy was assigned. (This will be either a value from 0 - 7 or No-override.) Syntax: show qos type-of-service Displays a listing of codepoints, with any corresponding DSCP policy re-assignments for outbound packets. Also lists the (802.1p) priority for each codepoint that does not have a DSCP policy assigned to it. For example, suppose you want to configure the following two DSCP policies for packets received with the indicated DSCPs. Received DSCP 001100 001101 Policy DSCP 17 16 802.1p Priority 6 4 Policy Name (Optional) Level 6 Level 4 1. Determine whether the DSCPs already have priority assignments, which could indicate use by existing applications. This is not a problem as long as the configured priorities are acceptable for all applications using the same DSCP. (Refer to the "Note On Changing a Priority Setting" on page 5-34
