spx unit
Without prior configuration, the SPX unit joins an SPX domain as a dynamic PE, and its dynamic configuration is lost when it leaves.
CB configuration mode
PE configuration mode
Provisional-PE configuration mode
The
no form of the command removes a reserved SPX unit. It can be entered only from a CB
unit. An error message is displayed if the
no form of the command is entered for a live unit, and the command fails. As an exception,
you can remove a live unit that is in a non-operational state due to configuration
(module) mismatch. In this case, the CB can remove the configuration, learn the modules
from the PE unit, and place it in a ready state.
A CB unit can configure an SPX unit with a unit number from 17 through 56. A PE or provisional PE can only configure unit 1 (itself) and does not have knowledge of its future ID number in the SPX domain.
These command can be configured under
spx unit:
spx-name,
module,
spx-port,
spx-lag. On a PE or provisional PE, the
module command cannot be configured.
If you configure parameters for a live SPX unit, the CB pushes the new configuration to the live unit immediately.
When you create a reserved SPX unit, you must configure modules for the unit. Modules can only be configured on a CB unit.
The following example creates a configuration for SPX unit 18 from a CB.
device# configure terminal device(config)# spx unit 18 device(config-spx-unit-18)# spx-name bldg2-floor2-stk 18 device(config-spx-unit-18)# module 1 icx7450-48f-sf-port-management-module device(config-spx-unit-18)# module 2 icx7400-xgf-4port-40g-module device(config-spx-unit-18)# module 4 icx7400-qsfp-1port-40g-module
The following example configures an SPX port and an SPX LAG from a CB.
device# configure terminal device(config)# spx unit 21 device(config-spx-unit-21)# spx-port 21/2/4 device(config-spx-unit-21)# spx-lag 21/1/10 to 21/1/11 device(config-spx-unit-21)# exit
The following example first shows a PE being created, with system-generated ports
and module information. The SPX number is always 1 in PE or Provisional-PE configuration
mode. SPX ports 1/2/1 and 1/2/3 are generated by the system in this case because there
is a 4 X 10-Gbps module in slot 2. The example then shows a user modification to a
LAG and an SPX port, still in Provisional-PE mode. As indicated in system messages,
you should use the
write memory command to save the configuration.
device(config)# spx pe-enable Enter provisional PE mode. CLI is limited to spx unit 1. After finishing all configuration, please "write memory" and reload this unit to be a PE.
