How Do I Determine the Port Status Through Indicators After a 40GE Port Is Split into Four 10GE Ports?

How Do I Determine the Port Status Through Indicators After a 40GE Port Is Split into Four 10GE Ports?

CloudEngine 12800 and 12800E

When a 40GE port on these cards is configured as four 10GE ports, the four indicators (1, 2, 3, 4) on the right of the panel show the sequence numbers of the 10GE ports. A CE-L12LQ-EF card is used as an example here to describe the indicators.

Description

1

One single-color indicator for each port

NOTE:

Arrowheads show the positions of ports. A down arrowhead indicates a port at the bottom, and an up arrowhead indicates a port at the top.

Green

  • Steady on: A link has been established on the port.
  • Blinking: The port is transmitting or receiving data.
NOTE:
  • A port indicator shows the status of the corresponding 40GE port by default.
  • After a 40GE port is configured as four 10GE ports, this indicator shows the status of a 10GE port. The indicated 10GE port is identified by sequence number indicators 1, 2, 3, 4. For the mapping between the four 10GE ports and sequence number indicators, see Figure 22-103. For example, if indicator 1 is on, the port indicator shows the status of the first 10GE port derived from the 40GE port

40GE Breakout button, used to manually control the 10GE port sequence number indicators

When one or more 40GE ports are split into four 10GE ports, these indicators identify the sequence numbers of the 10GE ports.

  • Automatic control mode: Indicators 1, 2, 3, 4 turn on in cyclic order, with each indicator keeping on for 5s.
  • Manual control mode: Press the 40GE Breakout button to turn on the 10GE port sequence number indicators cyclically. For example, if you press the 40GE Breakout button when indicator 3 is on, indicator 3 is still on. When you press the button a second time, indicator 4 turns on. Indicators 1 and 2 turn on in sequence when you press the 40GE Breakout button a third and fourth time. The control mode restores to the default automatic mode 60s after you stop pressing the 40GE Breakout button.
NOTE:

The automatic control mode is used by default.

An optical port indicator (1 in Figure 22-103) shows the status of a 10GE port derived from the corresponding 40GE port:

  • When indicator 1 is on, each 40GE port indicator shows the status of the first 10GE port derived from the corresponding 40GE port.
  • When indicator 2 is on, each 40GE port indicator shows the status of the second 10GE port derived from the corresponding 40GE port.
  • When indicator 3 is on, each 40GE port indicator shows the status of the third 10GE port derived from the corresponding 40GE port.
  • When indicator 4 is on, each 40GE port indicator shows the status of the fourth 10GE port derived from the corresponding 40GE port.

The following is an example:

The first two 40GE ports (0 and 1) shown in Figure 22-103 are both split into four 10GE ports, and the other 40GE ports (2 to 11) are not split.
  • When indicator 1 is on, the indicator of 40GE port 0 shows the status of the first 10GE port derived from 40GE port 0, and the indicator of 40GE port 1 shows the status of the first 10GE port derived from 40GE port 1. Indicators of 40GE ports 2 to 11 still show the status of these 40GE ports.
  • When indicator 2 is on, the indicator of 40GE port 0 shows the status of the second 10GE port derived from 40GE port 0, and the indicator of 40GE port 1 shows the status of the second 10GE port derived from 40GE port 1. Indicators of 40GE ports 2 to 11 still show the status of these 40GE ports.

CE6850-48T4Q-EI is used as an example here to describe usage of the indicators after 40GE ports are split into 10GE ports.

After a 40GE port on the CE6850-48T4Q-EI is configured as four 10GE ports, the 10GE port numbers are identified by 40GE Breakout indicators 1, 2, 3, 4, as shown in Figure 22-104.

40GE Breakout indicators 1/2/3/4

NOTE:

When one or more 40GE ports are split into four 10GE ports, these indicators identify the sequence numbers of the 10GE ports.

Indicators 1, 2, 3, 4 turn on in cyclic order, with each indicator keeping on for 5s.

An optical port indicator (1 in Figure 22-104) shows the status of a 10GE port derived from the corresponding 40GE port:

  • When indicator 1 is on, each 40GE port indicator shows the status of the first 10GE port derived from the corresponding 40GE port.

  • When indicator 3 is on, each 40GE port indicator shows the status of the third 10GE port derived from the corresponding 40GE port.
  • When indicator 4 is on, each 40GE port indicator shows the status of the fourth 10GE port derived from the corresponding 40GE port.

The following is an example:

The first two 40GE ports (1 and 2) shown in Figure 22-104 are both split into four 10GE ports, and the last two 40GE ports (3 and 4) are not split.
  • When Breakout indicator 1 is on, the indicator of 40GE port 1 shows the status of the first 10GE port derived from 40GE port 1, and the indicator of 40GE port 2 shows the status of the first 10GE port derived from 40GE port 2. Indicators of 40GE ports 3 and 4 still show the status of the two 40GE ports.
  • When Breakout indicator 2 is on, the indicator of 40GE port 1 shows the status of the second 10GE port derived from 40GE port 1, and the indicator of 40GE port 2 shows the status of the second 10GE port derived from 40GE port 2. Indicators of 40GE ports 3 and 4 still show the status of the two 40GE ports.
