Write CTE
Description A write CTE operation writes the CTE configuration table from the specified data
(DATABUF) to a specified Ethernet configuration extension table or to a specific slot.
To program an MBP_MSTR block to perform a write CTE operation, use function
code 12 (see Operational Function Codes, p. 151).
Network
Implementation
A write CTE operation can be performed on TCP/IP Ethernet (see TCP/IP Ethernet
Network Statistics, p. 174) and SY/MAX Ethernet networks.
