Performing Network and System Management
This chapter describes the network settings, the system management features, and ways to improve
the performance of the STM. If you have used the Setup Wizard, you have already configured
some of these settings, but there are situations in which you might want to modify them. This
chapter contains the following sections:
• “Configuring Network Settings” on this page.
• “Configuring Session Limits and Timeouts” on page 3-5.
• “Configuring the HTTP Proxy Settings” on page 3-7.
• “About Users with Administrative and Guest Privileges” on page 3-9.
• “Configuring Remote Management Access” on page 3-11.
• “Using an SNMP Manager” on page 3-13.
• “Managing the Configuration File” on page 3-16.
• “Updating the Software” on page 3-19.
• “Configuring Date and Time Service” on page 3-23
• “Managing Digital Certificates” on page 3-25
• “Managing the Quarantine Settings” on page 3-30
• “Performance Management” on page 3-31.
Configuring Network Settings
If you have used the Setup Wizard, you might already have configured the Web Management
Interface and maximum transmission unit (MTU) settings; the Network Settings screen allows you
to modify these settings and to specify the interface speed and duplex settings.
The STM requires a valid IP address to retrieve online updates and to enable access to its Web
Management Interface. If you have used the Setup Wizard to configure the STM, you have already
specified the the management interface name and address settings and the size of the MTU. In
addition to modifying these settings, the Network Settings screen also allows you to specify the
interface speed and duplex settings for the management interface, for the STM600 or STM300
uplink and downlink interfaces, or for the STM150’s WAN and LAN interfaces.
