Adding a Reserved PE Configuration on the CB
PE unit configuration present in the CB active controller before the corresponding PE unit joins the CB is called reserved PE configuration.
You can create PE configuration on the CB to be applied later to a joining PE unit. You must specify an SPX unit number and the ICX 7150, ICX 7250, or ICX 7450 modules that match the new PE unit.
When you configure a reserved PE unit on the CB, the system does not generate any SPX ports by default. The system learns SPX ports or LAGs from the PE unit when it joins. If you configure SPX ports or LAGs as part of a reserved unit, the CB will push your port or LAG configuration to the PE unit when it joins, after checking that the SPX port or LAG configuration will not break its connection with the PE.
pe-id configuration under the
spx cb-configure command. If the joining PE port does not match any
pe-id configuration, it is assigned its old ID if it is available. If the joining unit
has no old ID or the old ID is not available, it is assigned an unused ID.

Once you have configured a reserved PE unit, you can verify your configuration by
entering the
show running-config command. Configured modules are listed, along with SPX ports or LAGs, if any. SPX
unit 20 configuration, a reserved PE configuration, is displayed after stack unit
configuration. The following example shows no SPX ports. SPX ports or LAGs will be
learned and added to the configuration when a matching PE joins the CB.
