Ports

This topic describes the features, numbering rules, names, types, and quantities of the CX920 ports.

The CX920 provides ports for users to operate and configure. The ports are used to send and receive data.

The CX920 Ethernet ports are numbered in Slot number/Subcard number/Port number format.

  • Slot number: indicates the slot number of the current switch module. The value ranges from 1 to 4, mapping to slot numbers 1E, 2X, 3X, and 4E.
  • Subcard number: indicates the number of a subcard supported by service ports. The value ranges from 1 to 19.
  • Port number indicates the serial number of the port on the subcard.

For details about the values, see Figure 2-5, Table 2-2, and Table 2-3.

For example, if the CX920 is in slot 2X, the first 10GE optical port on the upper right on the panel is numbered 10GE 2/17/8, as shown in Figure 2-5.

The serial ports include a BMC port and a SYS port. These two ports comply with RS232 and have no indicators.

  • BMC port: used to log in to the BMC CLI and represented by the bcmcom option on the CLI.
  • SYS serial port: used to locally manage, maintain, and commission the 10GE switching plane and 40GE switching plane.
NOTE:

The SYS serial port corresponds to the following two options:

  • fabriccom: serial port connecting to the Ethernet switching plane.
  • basecom: serial port connecting to the Base switching plane.

The serial port baud rate of the BMC, 10GE switching plane and 40GE switching plane is 115200 bit/s.

10GE optical port

SFP+

8

17

The value ranges from 1 to 8.

The 10GE switching plane provides eight 10GE optical ports to connect to external networks.

Each port has two indicators: the orange one indicates data transmission status, and the green one indicates the port connection status.

40GE optical port

QSFP+

8

17

The value ranges from 1 to 8.

The 40GE switching plane provides 40GE optical ports to connect to external aggregation and core switches or to stack switch modules. Each port provides one indicator. Ports 1 to 6 can be split into four 10GE ports. Ports 7 and 8 cannot be split.

Naming rules for split ports: If port 40 GE1/17/1 is split, the numbers of the four split ports are 40GE 1/17/1:1 to 40GE 1/17/1:4.

Table 2-3 describes the internal ports of the 10GE switching plane of the CX920. Table 2-4 describes the internal ports of the 40GE switching plane.

10GE port

-

16

1 to 16

The port number is 1.

The ports connect to the LOMs of the front blades in slots 01 to 16. The 16 subcard numbers of the ports map to the 16 front slot numbers. Theses ports are available only when the switch module is in slot 2X or 3X.

If the CX920 is in slot 2X, the port connected to the compute node in slot 1 is numbered 10GE 2/1/1.

40GE port

-

1

18

The port number is 1.

The port is used to interconnect the switch modules in slots 1E and 4E or in slots 2X and 3X.

If the CX920 is in slot 2X, the port is numbered 40GE 2/18/1.

GE port

-

2

19

The port number ranges from 1 to 2.

The two GE ports connect to and communicate with two MM910s.

If the CX920 is in slot 2X, the ports are numbered GE 2/19/1 and GE 2/19/2.

1 to 16

The port number is 1.

The ports are connected to front half-width slots 01 to 16. The 16 subcard numbers of the ports map to the 16 front slot numbers.

Each of ports 1 to 16 can be split into two 20GE ports.

Naming rules for split ports: If port 40GE 2/1/1 is split, the numbers of the two split ports are 40GE 2/1/1:1 and 40GE 2/1/1:2.

If the CX920 is in slot 2X, the port connected to the compute node in slot 1 is numbered 40GE 2/1/1.

40GE port

2

18

The port number ranges from 1 to 2.

The port is used to interconnect the switch modules in slots 1E and 4E or in slots 2X and 3X.

This port can be used as a stack port.

If the CX920 is in slot 2X, the ports are numbered 40GE 2/18/1 and 40GE 2/18/2.
