6.6 Provisioning Stack Members
This function provides users to do the offline configuration for a switch before it joins to the stack. The
switch ID is automatically assigned from lowest unused number in the range of 1 to 8. Usually, the stack
master will have the lowest switch ID unless you configure the stack with move management command
or the re-election process was executed.
User could create stack members from the stack master with a unique member number (switch ID) and
configure the functionality in advance for this preconfigured switch that is not currently part of the stack.
If you add a switch with the identical model into the stack, and the new switch is using the same member
number (switch ID), then the new switch will be applied with the pre-configured/provisioned configuration
by the stack master.
User Assigned Name (UAN) in Provisioning State
The UAN is a unique id for a connection blade and, as a great advantage, is slot related. Therefore the
UAN should be used for addressing the interfaces even if a stack member is in provisioning state. This
would allow to restore the configuration of a stack member even if the member is replaced by a
connection blade with a different switch id. The stack maintenance would become much easier.
1. The stack master should save the UAN along with the switch id of stack members if a member is
removed from the stack (either because of unplugging or rebooting or malfunction). This means
that a provisioned member can also have a provisioned name. These names have to be hold in
nonvolatile memory since they must survive a reboot.
2. For the command ‘switch <id> provision’ optionally a UAN string can be specified after the
‘provision’ parameter. If specified this string should be used as provisioned name of the member.
If the specified UAN string is already assigned to another provision entry or already used as UAN
name by a present member it should be rejected.
3. If a provisioned member has a provisioned name (UAN) it should be used in the interface
specifications of the configuration instead of the switch id. This means that the UAN is continued
to be used for interface addressing in the running config if a member has been removed from the
stack.
Further interface specifications using the provisioned name of a provisioned member should be
accepted by configuration commands operating on interfaces. If the switch id is used for
addressing interfaces it should be replaced by the provisioned name.
As a result there should be no interface specifications in the running config which is based on the
switch id of a provisioned member with a provisioned name.
4. The provisioned name should be displayed in the ‘Name’ column of ‘show switch’ and ‘show
unit-identifier-alias’ commands.
5. If a new stack member is detected by the master he should check if the UAN of the new member
equals to the provisioned name of one of his provisioned entries.
− If found the provision entry should be used for the new member. This means that the switch
id of the new member should be changed to the switch id of the provision entry. Since solely
