C6K_MPLS_RP Messages
Error Message %C6K_MPLS_RP-2-NO_IP_QOS_RSVD_VLAN: IP QoS features will not be
applied to MPLS->IP packets due to a lack of internal VLAN resources
Explanation
The total number of VLANs in use might have exceeded 4096. The VLAN resources are
shared by VLANs used for SVI, VLANS used for subinterfaces, hidden VLANs used for routed
ports, and internal VLANs used for some VRFs. An internal VLAN is needed when an IP QoS
feature is applied to a VRF interface. If the total number of VLANs in use exceeds 4096, no more
internal VLANs can be allocated, so IP QoS features will not be applied to MPLS-to-IP packets.
Recommended Action Reduce the total number of VLANs in use by removing SVI interfaces,
subinterfaces, and/or VRF interfaces.
C6K_MPLS_RP-3
Error Message %C6K_MPLS_RP-3-L2_CONFIG_NOT_RECOMMENDED: xconnect is configured on
interface vlans and WAN interfaces are facing the MPLS Core. Do not configure LAN
interfaces facing the MPLS Core.
Explanation
An attempt was made to configure a LAN interface to face the MPLS core. The current
network configuration has cross-connection services configured on interface VLANs and has WAN
interfaces facing the MPLS core.
Recommended Action Do not configure MPLS on LAN interfaces facing the MPLS core if the
network has cross-connection services configured on an interface VLAN and WAN interfaces that
face the MPLS core.
Error Message %C6K_MPLS_RP-3-L3_CONFIG_NOT_RECOMMENDED: LAN interfaces are facing
the MPLS Core. Do not configure xconnect on interface vlans.
Explanation
An attempt was made to configure a cross-connection service on an interface VLAN.
The current network configuration has MPLS configured on a LAN interface that is facing the MPLS
core.
Recommended Action Do not configure cross-connection services on an interface VLAN if the
network has MPLS configured on a LAN interface.
