## SYSLOG Details
- **Message**: Delay buffer rate cannot exceed total transmission rate of IFL(<variable>logical-interface-index</variable>) hosted on the L2TP session(ID:<variable>cos-node-name</variable>) of node type <variable>session-id</variable>
- **Help**: L2TP delay-buffer-rate exceeds interface speed
- **Description**: The delay-buffer-rate for Layer 2 Tunneling Protocol (L2TP) session hosted on the logical-interface(IFL) exceeds the total transmission-rate of the interface
- **Type**: Error: An error occurred
- **Severity**: error
- **Cause**: Delay-buffer-rate configuration
- **Action**: Configure L2TP delay-buffer-rate less than the interface speed
- **Attributes**: logical-interface-index
cos-node-name
session-id
- **Facility**: LOG_DAEMON
