qos map default-drop-
precedence
This command maps the internal per-hop behavior (based on packet priority) to a
default drop precedence for internal processing of untagged packets. Use the
no
form to restore the default settings.
Syntax
qos map default-drop-precedence drop-precedence from phb0 ... phb7
no map default-drop-precedence phb0 ... phb7
drop-precedence - Drop precedence used for controlling traffic congestion.
(Range: 0 - Green, 3 - Yellow, 1 - Red)
phb - Per-hop behavior, or the priority used for this router hop. (Range: 0-7)

Command Usage
◆
Enter a drop precedence, followed by the keyword “from” and then up to four
per-hop behavior values separated by spaces.
◆
This command only applies to Layer 2 untagged ingress packets. The drop
precedence for any priority tagged ingress packets will be based on the other
corresponding QoS mapping schemes described in those sections.
Example
Console(config)#interface ethernet 1/5
Console(config-if)#qos map default-drop-precedence 1 from 0 1 2
Console(config-if)#qos map default-drop-precedence 3 from 3 4 5
Console(config-if)#qos map default-drop-precedence 0 from 6 7
Console(config-if)#
