show spx

Displays information on the Switch Port Extender (SPX) topology.
Syntax
show spx
Modes

CB configuration mode

PE mode

PE configuration mode

Usage Guidelines

The command can be issued from a control bridge (CB) or a port extender (PE); however, the display from a PE is limited to information about the PE itself.

The show spx command displays the following information:

Output Field Description
ID The SPX unit ID (CB or PE; PE units are numbered from 17 to 56).
"S" or "D" Static (S) or Dynamic (D). Indicates whether the configuration has been saved to memory. Dynamic configurations are lost when the unit is removed.
Type The model (SKU) of the FastIron device.
Role Lists the role of the unit in the SPX system, from the following values: active (active controller in the CB stack), member (CB stack member), standby (standby controller for the CB stack), or spx-pe (PE unit).
Mac Address The MAC address of the unit.
Pri The priority of the unit.
State Displays the state of the unit, from the following values: Local (unit from which the command was entered), remote (unit is not local), or reserve (indicates a reserved, rather than an active, unit).
Comment

Ready (unit is operational).

Synchronizing (output example: 21 S ICX7450-24G spx-pe cc4e.248b.a448 N/A remote Synchronizing (st=13)).

Examples

The following example displays information for a CB standalone with two attached PE units.

The following example shows output for a CB stack. The output includes warning messages that appear when the system detects a mismatch in port number for an operational port in any link.
