Abstract
According to one embodiment, a method may include writing a congestion forward indicator (CFI) bit of an outer virtual local area network (VLAN) tag in an Ethernet frame to one of a first setting or a second setting, reading the CFI bit of the outer VLAN tag at a switching element, copying priority (PRI) bits of the outer VLAN tag to PRI bits of an inner VLAN tag if the CFI bit of the outer VLAN tag is set to the first setting, and maintaining the state of the PRI bits of the inner VLAN tag if the CFI bit of the outer VLAN tag is set to the second setting.
