WebMar 17, 2024 · From reading technical articles from Aruba, the DSCP to 802.1d UP is mapped using the first 3 bits of the last 6 bits of the DSCP. DSCP 46 = 0X2e = 0010 1110 = use 101 = 5. So a traditional wired voice tag of DSCP 46 is 802.1d UP of 5. Issue is that the 802.1d UP value of 5 is classified in wmm as video. 7/6 is voice.
