Comparing Switch Management Methods | NETGEAR 7200 Series manual

User Manual for the NETGEAR 7200 Series Layer 2 Managed Switch Software

•Simple Network Protocol Management (SNMP)

Each management method enables the network administrator to configure, manage, and control the GSM7224 locally or remotely using in-band or out-of-band mechanisms. Management is standards-based, with configuration parameters and a private MIB providing control for functions not completely specified in the MIBs.

Table 2-1.	Comparing Switch Management Methods

Management Method		Advantages	Disadvantages
Administration		• Out-of-band access via direct cable	• Must be near switch or use dial-up
console		connection means network bottlenecks,	connection
		crashes, and downtime do not slow or	• Not convenient for remote users
		prevent access	• Not graphical
		• No IP address or subnet needed
		• Menu or CLI based
		• HyperTerminal access to full functionality
		(HyperTerminal are built into Microsoft
		Windows 95/98/NT/2000 operating
		systems)
		• Secure – make sure the switch is installed
		in a secure area.
