Syntax
qos trust [default|dot1p|dscp|ip-prec|none|device [none|<DEVICE-TYPE>]]
Description
Set the QoS Trust Mode configuration for the port.
Options
- default
Trust 802.1p priority and preserve DSCP or IP-ToS.
- device <DEVICE-TYPE>
On approved devices, trust IP-ToS Differentiated-Services in IP packets, and use the DSCP-MAP to remark the 802.1p priority. If the DSCP codepoint does not have an associated priority, the priority will be remarked to 0. On unapproved devices, trust 802.1p priority and preserve any IP- ToS values.
- dot1p
Trust 802.1p priority and preserve DSCP or IP-ToS.
- dscp
Trust IP-ToS Differentiated-Services in IP packets, and use the DSCP-MAP to remark the 802.1p priority. If the DSCP codepoint does not have an associated 802.1p priority, the priority will be remarked to 0.
- ip-precedence
Trust IP-ToS IP-Precedence mode in IP packets and remark the 802.1p priority.
- none
Do not trust either the 802.1p priority or the IP-ToS values.
QoS trust devices
Both SNMP and the CLI will verify that the current QoS Port Priority and desired QoS Trust Mode configuration are not mutually exclusive (and conversely).
