# [COSD_HIGH_PRIO_QUEUES_INTERFACE](https://apps.juniper.net/syslog-explorer/?msg=COSD_HIGH_PRIO_QUEUES_INTERFACE)

## SYSLOG Details
- **Message**: Unable to apply scheduler map <variable>scheduler-map</variable> to interface <variable>interface-name</variable>, because multiple schedulers in map have "high,""medium-high," or "strict-high" priority
- **Help**: Multiple schedulers for interface have high-level priority
- **Description**: The class-of-service (CoS) process (cosd) did not apply the indicated scheduler map to the indicated interface, because the map includes more than one scheduler that has high, medium-high, or strict-high priority. For interfaces that are housed by certain PICs, such as an IQ2 PIC, the scheduler map can include only one scheduler that specifies one of those three priority levels. In terms of configuration, the 'priority' statement at the [edit class-of-service schedulers &lt;scheduler-name>] hierarchy level has the value 'high, ' 'medium-high, ' or 'strict-high' for more than one of the schedulers in the map.
- **Type**: Error: An error occurred
- **Severity**: error
- **Cause**: -
- **Action**: Correct the configuration so that the scheduler map includes only one scheduler with high, medium-high, or strict-high priority.
- **Attributes**: scheduler-map
interface-name
- **Facility**: LOG_DAEMON
