I am using different
SNMP community
strings for different
devices on my
network - how do I
specify this?
3Com recommends that you change the community strings on your
network devices from the factory defaults. You may want to leave the
read community strings as public for your switches but may wish to
change them to something more secure for your routers.
To specify a community string for a network device for use during
discovery, do the following:
1 Launch the Network Discovery wizard (e.g. by selecting Tools > Network
Discovery).
2 Navigate through the wizard until you reach the Community Strings pane
