Chapter 24 Configuring PFC3BXL and PFC3B Mode Multiprotocol Label Switching
Any Transport over MPLS
–
Outgoing tag or VC—Label assigned by next hop.
–
Prefix or Tunnel Id—Address or tunnel to which packets with this label are going.
–
Bytes tag switched— Number of bytes switched out with this incoming label.
–
Outgoing interface—Interface through which packets with this label are sent.
–
Next Hop—IP address of neighbor that assigned the outgoing label.
• To view the state of the currently routed VCs, enter the show mpls l2transport vc command.
Router# show mpls l2transport vc
Local intf Local circuit Dest address VC ID Status
------------- -------------------- --------------- ---------- ----------
Vl2 Eth VLAN 2 11.11.11.11 2 UP
Vl3 Eth VLAN 3 11.11.11.11 3 UP
To see detailed information about each VC, add the keyword detail.

Configuring PFC3BXL or PFC3B Mode Port-Based EoMPLS
When configuring PFC3BXL or PFC3B mode port-based EoMPLS, follow these guidelines and
restrictions:
• The AToM control word is not supported.
• Ethernet packets with hardware-level cyclic redundancy check (CRC) errors, framing errors, and
runt packets are discarded on input.
