Due to ASIC limitation, there are some 100GE interfaces on certain platforms do not support port splitting. The following table gives a summary.

NOTE:

For AS7726-32X, AS7326-56X, N8550-48B8C and N8550-32C, by default, there are no such limitation described in the below table. The limitation of port breakout only happens when the 10G-Base-KR ports are enabled as either front panel ports or management ports. For details about 10G-Base-KR ports, see 10G-Base-KR Interface Configuration.

Platform	Limitation Description
AS6812_32X	Ports xe-1/1/13, xe-1/1/14, xe-1/1/15, xe-1/1/16, xe-1/1/29, xe-1/1/30, xe-1/1/31 and xe-1/1/32 are not allowed to be split into four Gigabit Ethernet ports.
AS5835_54X/AS5835_54T/ N5850-48X6C	Only ports xe-1/1/1 and xe-1/1/4 can be split into four Gigabit Ethernet ports, other ports are not allowed to be split.
AS7726-32X	Port xe-1/1/32 is not allowed to be split into four Gigabit Ethernet ports.
N8550-32C	Port xe-1/1/32 is not allowed to be split into four Gigabit Ethernet ports.
AS7326-56X	Port xe-1/1/8 is not allowed to be split into four Gigabit Ethernet ports.
N8550-48B8C	Port xe-1/1/8 is not allowed to be split into four Gigabit Ethernet ports.
S5232F-ON	Port xe-1/1/32 is not allowed to be split into four Gigabit Ethernet ports.
AS7816-64X	Only the ports on the first row of front panel are allowed to do breakout, that is, only ports 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29 and 31 can be split into four Gigabit Ethernet ports.
Z9264F-ON	Only the ports on the first row of front panel are allowed to do breakout, that is, only ports 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29 and 31 can be split into four Gigabit Ethernet ports.
