MPLS Module Installation and User Guide 9-11
Attributes Not Directly Applicable to the MPLS Module
• Differentiated services (diffserv)
• Quality of Service (QoS)
• Spanning Tree Protocol (STP)
• RMON
• Access list
The MPLS module relies on the ingress switch fabric to support access list functions.
Thus, access list functions are not applicable to MPLS-encapsulated packets.
• IGMP snooping
OSPF and LDP session establishment require the MSM to receive and process IP
multicast frames. Therefore, IGMP snooping must be enabled to support MPLS.
• GVRP
GVRP is not supported over MPLS LSPs.
• Server Load Balancing (SLB)
SLB and MPLS are mutually exclusive functions. Both functions cannot be
simultaneously enabled.
• IP flow redirection
IP flow redirection commands and MPLS are mutually exclusive functions. Both
functions cannot be enabled simultaneously.
