show nodealias

This command has no arguments or variables.



Usage Guidelines

The following information about the Node Alias feature appears:
  • Max Entries—Total number of the entries learned through the Node Alias feature on the switch.
  • Active Entries—Number of the active entries learned through the Node Alias feature on the switch.
  • Purge Time—Last time an entry was purged from the Node Alias table on the switch.
  • State—State of the Node Alias table on the switch.
  • Protocols Enabled—Lists the currently enabled protocols that Node Alias detects.
  • Ports Enabled—Lists the currently Node Alias-enabled ports with each port's active and maximum (configured using configure nodealias ports [port_list |all] maxentries entries) number of alias entries. This information appears in the form: port # (active alias entries #/maximum alias entries #). For example, "1(2/10)".
