NOTEs:

1. The last two ports are 10G-Base-KR ports which can be configured as two 10G SFP+ ports on the front panel or two 10G-KR ports linked to CPU. By default, 10G-Base-KR ports are disabled. For details please refer to document 10G-Base-KR Interface Configuration.

2. On N8550-48B8C switch, when the 10G-Base-KR ports are enabled as either front panel ports or management ports, xe-1/1/8 port is not allowed to be split into four Gigabit Ethernet interfaces.

3. The first 48 ports are grouped as shown in the following table, four ports form a group.

When configuring the rate, the supported port rates are 25 Gbit/s, 10 Gbit/s, and 1 Gbit/s. The four ports of a group can be configured with the same port rate or different rate. When configuring at different port rates, 10G and 1G can coexist, but 25G cannot coexist with 10G or 1G. The following table gives several cases of speed setting for the group of ports.
