Command Usage
◆ The default mapping of CoS/CFI to Queue/CFI values shown in Table 103 is
based on the recommended settings in IEEE 802.1p for mapping CoS values to
output queues.
◆ Enter a value for the per-hop behavior, followed by the keyword “from” and
then up to eight CoS/CFI paired values separated by spaces.
◆ If a packet arrives with a 802.1Q header but it is not an IP packet, then the
CoS/CFI-to-Queue mapping table is used to generate priority for processing.
Note that priority tags in the original packet are not modified by this command.
Example
Console(config)#interface ethernet 1/2
