Chapter 1 Using Express Setup
Configuring the Switch Settings
If you enable SNMP, you must enter a community string in the SNMP Read
Community field, the SNMP Write Community field, or both. SNMP
community strings authenticate access to MIB objects. Embedded spaces are not
allowed in SNMP community strings. If you set the SNMP read community, users
can access MIB objects, but cannot modify them. If you set the SNMP write
community, users can access and modify MIB objects.
Step 13 Click Save to save your settings to the switch, or click Cancel to clear your
settings.
The switch exits Express Setup mode.
Your switch is now configured with the new IP address. You can install the switch
in your production network.
Rerunning Express Setup
If you did not click Save at the end of the “Configuring the Switch Settings”
section, you can rerun Express Setup by clicking Express Setup on the Express
Setup home page (see Figure 1-7).
If you have entered a wrong IP address or need to change the IP address of your
switch, you can clear the IP address on your switch by following the steps in the
“Clearing the Switch IP Address and Configuration” section on page 4-2.
Verifying the Switch IP Address
This procedure is optional. After you have installed the switch in your network,
follow these steps to verify the IP address that is configured on your switch:
Step 1 Launch a web browser on a PC or workstation that is connected to the network.
Step 2 Enter the IP address of your switch (for example: 172.20.139.142). The switch
home page appears, as shown in Figure 1-8.
