Locating Other Switches

The Locate Switches option uses SNMPv2 and discovers devices responding to SNMP requests with the
read-only community string public.
To locate switches that are not included in the currently discovered fabric, follow these steps:
Choose Locate Devices by Subnet from the Fabric Manager File menu.
Step 1
You see the Locate Switches dialog box.
Step 2 Enter a range of specific addresses belonging to a specific subnet which limit the research for the
switches. To look for a Cisco MDS 9000 switch belonging to subnet 192.168.199.0, use the following
string:
192.168.100.[1-254]
Multiple ranges can be specified, separated by commas. For example, to look for all the devices in the
two subnets 192.168.199.0 and 192.169.100.0, use the following string:
192.168.100.[1-254], 192.169.100.[1-254]
Step 3 Enter the appropriate read community string in the Read Community field.
The default value for this string is "public."
Step 4 Click Display Cisco MDS 9000 Only to display only the Cisco MDS 9000 Family switches in your
network fabric.
Step 5 Click Search to discover switches and devices in your network fabric. You see the results of the discovery
in the Locate Switches window.
