I posted this in another HP forum and I was told I should probably post here

I've got an HP Procurve 1810-24g v2. According to the documentation it supports mapping DSCP to 802.1p.
I cannot find any documentation on how it maps the many DSCP codes to the 802.1p codes.
I could try to make an educated guess, but I have two conflicting thoughts on this
1) The 1810v2 maps the 8 802.1p codes to 4 internal queues. DSCP has 4 primarly classifications that they recommend, so I thought these 4 classes would map to the 4 internal queues.
2) There are 8 other DSCP classifications, 4 of which are subsets of the 4 primary classifications.
I have no idea if the 8 classifications map to the 8 802.1p classifications and would be prooperly mapped to the 4 hardware queues or if the first 4 classfications would be considered part of the 4 primary classfications and get mapped directly to the hardware queues.
Does ECN break these mappings? ECN changes the two rightmost bits in the ToS field, which is used by DSCP.
If the 1810v2 maps the 8 Class selector values to the 8 802.1p queues, the Class selector values don't use the 3 right most bits, so if the 1810v2 only looks at the left most bits, then it should be fine.
