Configuration manual

NOTE: When you split a 40G port (such as fo 0/4) into four 10G ports, the 40G interface
configuration is available in the startup configuration when you save the running configuration by
using the write memory command. When a reload of the system occurs, the 40G interface
configuration is not applicable because the 40G ports are split into four 10G ports after the reload
operation. While the reload is in progress, you might see error messages when the configuration file
is being loaded. You can ignore these error messages. Similarly, such error messages are displayed
during a reload after you configure the four individual 10G ports to be stacked as a single 40G port.
• Split a single 40G port into 4-10G ports.
CONFIGURATION mode
stack-unit port number portmode quad
– stack-unit: Enter the stack member unit identifier of the stack member to reset. The range is
from 0 to 5.
– port <port number> : Enter the port number of the 40G port to be split. The valid values on
base module: 33 or 37; OPTM SLOT 0: 41 or 45; OPTM SLOT 1: 49 or 53.
– portmode quad: Identifies the uplink port as a split 10GbE SFP+ port.
To display the stack-unit number, enter the show system brief command.
• Save the configuration and reload the switch.
CONFIGURATION mode
write memory
reload
Merging SFP+ Ports to QSFP 40G Ports
To remove FANOUT mode in 40G QSFP Ports, use the following commands.
1. Merge 4-10G ports to a single 40G port.
CONFIGURATION mode
no stack-unit port number portmode quad
• stack-unit: Enter the stack member unit identifier of the stack member to reset. The range is
from 0 to 5.
• port <port number>: Enter the port number of the 40GbE QSFP+ port. Valid values on base
module: 33 or 37; OPTM SLOT 0: 41 or 45; OPTM SLOT 1: 49 or 53.
• portmode quad: Identifies the uplink port as a split 10GbE SFP+ port.
2. Save the configuration and reload the switch.
CONFIGURATION mode
write memory
reload
Important Points to Remember
• You cannot use split ports as stack-link to stack an MXL Switch.
• Split ports cannot be a part of any stacked system.
• The quad port must be in a default configuration before it can be split into 4x10G ports.
