By default, the rear module is used for stacking with two 100-Gbps ports.
Global configuration mode
The command applies to ICX 7650 devices only.
Use the
no form of the command to return the module to default operation.
100-Gbps and 40-Gbps operation require different optics. If optics do not match the configuration, the port link is down.
Local and remote ports connected through the rear module must operate in the same mode.
The rear-module
command stacking options are allowed only when no uplink configuration is present
on the rear module.The
rear-module command cannot be used to configure uplink ports once the stack is formed. Refer
to the
FastIron Stacking Configuration Guide for information on enabling stacking or removing configuration.
You are, however, allowed to enter stacking configuration while the rear module operates
in uplink mode. The stacking configuration remains offline, and stacking election
is blocked. Once you enter the
write memory command, the system prompts you to save or erase the stacking configuration.
You must execute the
write memory and
reload commands for any change to the
rear-module setting to take effect.
The following example configures the rear module to operate in 40-Gbps stacking mode.
device# configure terminal device(config)# rear-module stack-40G device(config)# exit device# write memory device# reload
