– The router is configured with multiple ECMP paths
– MPLS IP is not enabled on one of the ECMP paths
Workaround: There is no workaround.
• CSCud35689
Symptoms: The router accepts a queue-limit configuration at the parent level of a policy or at the
Vlan class/ port level. This configuration is not supported.
Conditions: Occurs when you add a queue-limit configuration on a policy at the parent level or at
the vlan class/ port level.
Workaround: There is no workaround.
