Netgear M4100-26G (GSM7224v2h2) - 22‐port GE + 4 GE Combo L2 Managed Switch Software Guide

This command updates the bootcode (boot loader) on the switch. The bootcode is read from 
the active-image for subsequent reboots. The optional <unit> parameter is valid only on 
Stacks. Error will be returned, if this parameter is provided, on Standalone systems. For 
Stacking, the <unit> parameter identifies the node on which this command must be 
executed. When this parameter is not supplied, the command is executed on all nodes in a 
Stack. 

This section describes the commands you use to view information about system features, 
components, and configurations. 

This command displays the contents of the IP stack’s Address Resolution Protocol (ARP) 
table. The IP stack only learns ARP entries associated with the management interfaces 
(network or service ports). ARP entries associated with routing interfaces are not listed.

This command displays the event log, which contains error messages from the system. The 
event log is not cleared on a system reset. The <unit> is the switch identifier.
