Configuring Slots on NETGEAR 8800 Switches
This section describes how to configure slots on the NETGEAR 8800’s modular switches.
If a slot has not been configured for a particular type of module, then any type of module is
accepted in that slot, and a default port and VLAN configuration is automatically generated.
After any port on the module has been configured (for example, a VLAN association, a VLAN
tag configuration, or port parameters), all the port information and the module type for that
slot must be saved to non-volatile storage. Otherwise, if the modular switch is rebooted or the
module is removed from the slot, the port, VLAN, and module configuration information is not
saved.
Note: For information on saving the configuration, see Appendix B,
Software Upgrade and Boot Options.
You configure the modular switch with the type of input/output (I/O) module that is installed in
each slot. To do this, use the following command:
configure slot <slot> module <module_type>
You can also preconfigure the slot before inserting the module. This allows you to begin
configuring the module and ports before installing the module in the chassis.
If a slot is configured for one type of module, and a different type of module is inserted, the
inserted module is put into a mismatch state and is not brought online. To use the new
module type in a slot, the slot configuration must be cleared or configured for the new module
type. To clear the slot of a previously assigned module type, use the following command:
clear slot <slot>
All configuration information related to the slot and the ports on the module is erased. If a
module is present when you issue this command, the module is reset to default settings.
To display information about a particular slot, use the following command:
show slot {<slot>} {detail}
Information displayed includes:
• Module type, part number and serial number
• Current state (power down, operational, diagnostic, mismatch)
• Port information
If no slot is specified, information for all slots is displayed.
All slots on the modular switches are enabled by default. To disable a slot, use the following
CLI command:
disable slot
