This accessible-for-notify object carries a text string naming the Layer 3 service that failed to be delivered because of insufficient ACL resources. An admin reads this in a trap to identify exactly which Layer 3 feature is being denied due to exhausted ACL table space, rather than just seeing a generic resource alarm. For example, this string might read "QoS policy application", indicating that a QoS policy could not be applied to traffic because ACL resources were exhausted.
