14.5 Configuring 100GBASE-R and exclusive 100BASE-TX/1000BASE-T/10GBASE-T

This setting applies only to AX3660S-48XT4QW.

The factory-default setting is 40GBASE-R for ports 49-52, which are QSFP28/QSFP and shared ports. No 100GBASE-R is configured and all 100BASE-TX/1000BASE-T/10GBASE-T are enabled.

If QSFP28/QSFP + shared port is used in 100GBASE-R, the corresponding ports in ports 17 to 24 and ports 37 to 44 of 100BASE-TX/1000BASE-T/10GBASE-T port are disabled. The following tables show the correspondence between port numbers that use 100GBASE-R and 100BASE-TX/1000BASE-T/10GBASE-T ports that are disabled.

Table 14-9 Correspondence between Port Number Using 100GBASE-R and Disabled 100BASE-TX/1000BASE-T/10GBASE-T Port
Port number that uses 100GBASE-R (QSFP28/QSFP+ shared)	Port number to be disabled (100BASE-TX/1000BASE-T/10GBASE-T port)
No 100GBASE-R setting	No
Either 49 or 50	21, 22
Both 49 and 50	17, 18, 19, 20, 21, 22, 23, 24
Either 51 or 52	41, 42
Both 51 and 52	37, 38, 39, 40, 41, 42, 43, 44

<Structure of this section>

(1) Configuring QSFP28/QSFP + Shared Ports for 100GBASE-R

(1) Configuring QSFP28/QSFP + Shared Ports for 100GBASE-R

Set QSFP28/QSFP + shared port to 100GBASE-R. If the switch is restarted after configuration settings have been made, the specified ports can operate in 100GBASE-R. In addition, interface tengigabitethernet of the corresponding 100BASE-TX/1000BASE-T/10GBASE-T and its subordinate configuration are deleted.

Points to note: In this case, port 49 of QSFP28/QSFP+ shared port is set to 100GBASE-R assuming that port 50 of QSFP28/QSFP+ shared port is not set to 100GBASE-R. After the setting, ports 21 to 22 of the corresponding 100BASE-TX/1000BASE-T/10GBASE-T port are disabled.

Command examples

(config)# system interface hundredgigabitethernet 1/0/49 enable

After this command execute, please save configuration editing now in startup-config, and please reboot a device.

Do you wish to continue ? (y/n):

Set the port 49(QSFP28/QSFP+ shared port) to 100GBASE-R. Enter y for the configuration change confirmation message.
(config)# save

(config)# exit

Saves the configuration and returns to administrator mode from configuration command mode.
# reload

Restarts the Switch.

After reboot, PORT49 can operate in 100GBASE-R. Of 100BASE-TX/1000BASE-T/10GBASE-T ports, interface tengigabitethernet of ports 21 to 22 and the configurations under them are deleted.

Notes: If you configured it in a stacked configuration, restart all member switches that make up the stack.
