set Sets a given RMON register and its software 64-bit shadow register word to the

specified value.

reg RMON register number.

offset [0|1] Each RMON register is 64 bits wide divided into two 32-bit words. 0 and 1 specify

the high and low registers respectively.

value The 32-bit hex value to be placed into the high or low register specified by offset

above.

Both the high and low 32-bit words of the 64-bit register should be written. This requires two

command assumes that auto-negotiation is off. The available values are:

• 100fd 100 Mbps, Full Duplex

• 100hd 100 Mbps, Half Duplex
