CHAPTER 5: SWITCH MANAGEMENT OVERVIEW 
This chapter gives an overview of switch management, including the methods you can use to manage your NETGEAR Model GSM712 Managed 
Gigabit Switch. Topics include: 
Management Access Overview  
SNMP Access  
Protocols  
Software Upgrade Procedure 
 
Management Access Overview 
Your NETGEAR Model GSM712 Managed Gigabit Switch gives you the flexibility to access and manage the switch using any or all of the following 
methods:  
An administration console  
Web browser interface  
External SNMP-based network-management application 
 
The administration console and Web browser interface support are embedded in the switch’s firmware and available for immediate use. Each of 
these management methods has advantages. Table 5-1 compares the three management methods.

Management Method
 
Advantages
 
Disadvantages
 
Administration console
 
 
Out-of-band access via direct cable connection 
means network bottlenecks, crashes, and downtime 
do not slow or prevent access 
 
No IP address or subnet needed 
 
Menu-based 
 
HyperTerminal access to full functionality 
(HyperTerminal are built into Microsoft Windows 
95/98/NT/2000 operating systems) 
 
Secure – MAKE SURE THE AREA WHERE THE 
SWITCH IS INSTALLED IS A SECURE AREA
 
Must be near switch or use dial-up connection 
 
Not convenient for remote users 
 
Not graphical
 
 
Web browser
 
 
Can be accessed from any location via the switch’s 
IP address  
 
Ideal for configuring the switch remotely 
 
Compatible with Internet Explorer and Netscape 
Navigator Web browsers 
 
Familiar browser interface 
 
Graphical data available 
 
Most visually appealing
 
 
Security can be compromised (hackers need 
only know IP address and subnet mask) 
 
May encounter lag times on poor connections 
 
Displaying graphical objects over a browser 
interface may slow navigation
 
SNMP Agent
 
 
Communicates with switch functions at the 
Management Information Base (MIB) level 
 
Based on open standards
 
 
Requires SNMP manager software 
 
Least visually appealing of all three methods 
 
Limited amount of information available 
 
Some settings require calculations 
 
Security can be compromised (hackers need 
only know the community name)
