Trusted priority type Description
DSCP
1) The switch looks up the DSCP-precedence-to-other-prece
dence mapping table for the set of precedence values cor
responding to the DSCP value of the packet.
2) When configuring the switch to trust the DSCP precedence
of packets, you can further configure the switch to process
each received packet in one of the following modes:
z In the default mode, deliver the packet with its original
802.1p precedence value unchanged.
z In the automap mode, deliver the packet with the target
802.1p precedence value after mapping in place of its
original one.
z In the remap mode, look up the DSCP-precedence-to-DSC
P-precedence mapping table for a new DSCP value corres
ponding to the current DSCP value, then search for the set
of precedence values corresponding to the new DSCP val
ue in the DSCP-precedence-to-other-precedence mapping
table, and then deliver the packet with the target 802.1p pr
ecedence value after mapping in place of the original 802.
1p precedence value of the received packet.
The S5100-SI/EI series switches provide CoS-precedence-to-other-precedence,
DSCP-precedence-to-other-precedence, and DSCP-precedence-to-DSCP-precedence
mapping tables for priority mapping.
Table 1-6 through Table 1-10 list the default settings
of these tables.
