Setting switch SNMP properties
Use the SNMP Properties dialog box to define how authentication traps are managed and set for the
switch. SNMP is the protocol that governs network management and monitoring of network devices. SNMP
security consists of a read community string and a write community string, which are basically the
passwords that control read and write access to the switch.
CAUTION: The read community string public and write community string private are set at the factory to
these well-known defaults and should be changed if SNMP is enabled. If SNMP is enabled (default) and
the read and write community strings have not been changed from their defaults, you risk unwanted access
to the switch. It is very important that you consider how you want to manage the fabric and what switches
you do not want managed through another switch.
