When both DSCP and L2CoS are used

If an FCIP tunnel or circuit is VLAN tagged, both DSCP and L2CoS are relevant, unless the VLAN is

end-to-end, with no intermediate hops in the IP network. The following table shows the default

mapping of DSCP priorities to L2Cos priorities. This may be helpful when consulting with the WAN

administrator. These values may be modified per FCIP tunnel.
