Layer-2 and Layer-3 Switching Attributes

The MPLS module relies on the MSM switch fabric to support the layer-2
switching functions.
If MPLS is enabled, the switch fabric hardware does not perform layer-3 switching for
any protocols. The MPLS module performs layer-3 forwarding for IP.
All of the IP routing protocols are supported: RIP, OSPF, BGP, DVMRP, PIM.
IPX routing is not supported when MPLS is enabled.

Debug Trace Commands

System-level debug tracing is provided for the MPLS subsystem. To enable this support,
use the following commands:
config debug-trace mpls <level>
config debug-trace mpls-signalling <level>
The interface numbers displayed by the
mpls-signalling
config debug-trace mpls
commands) start at 0.
Attributes Not Directly Applicable to the MPLS
Module
The following attributes (and related commands) are not directly applicable to the
MPLS module:
• Port attributes
The MPLS module does not have any external ports. Therefore, the port commands
are not directly applicable to the MPLS module. The slot in which the MPLS module
cannot be used as part of a port specification in any command.
The MPLS module supports the MTU size configured using the
jumbo-frame size
9-10
command start at 1. The interface numbers displayed by the
command (and other ExtremeWare debug-trace
command.
