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

## SYSLOG Details
- **Message**: Unable to apply CoS to L2TP session <variable>session-id</variable>, because scheduler map <variable>scheduler-map</variable> specifies exact rate transmission
- **Help**: Exact transmission rate not applied to L2TP session
- **Description**: The class-of-service (CoS) process (cosd) did not apply CoS settings to the indicated Layer 2 Tunneling Protocol (L2TP) session, because the scheduler map specified by the RADIUS server for the session is configured for exact transmission rate. Exact transmission rate is not supported for L2TP sessions on the type of PIC that houses the interface, such as an IQ2 PIC. In terms of configuration, the 'exact' statement is included in a scheduler definition at the [edit class-of-service schedulers &lt;scheduler-name> transmit-rate (&lt;rate> | percent &lt;percentage>)] hierarchy level. The scheduler is included in a scheduler map that is associated with a traffic control profile. The traffic control profile is named by an attribute in the RADIUS server's configuration file, which makes the profile apply to the session.
- **Type**: Error: An error occurred
- **Severity**: error
- **Cause**: -
- **Action**: Remove the 'exact' statement from the scheduler in the scheduler map applied to the session.
- **Attributes**: session-id
scheduler-map
- **Facility**: LOG_DAEMON
