You can also enable or disable the Simple Network Management Protocol 
(SNMP). SNMP is the protocol governing network management and monitoring of 
network devices. SNMP security consists of a read community string and a write 
community string, that are the passwords that control read and write access to the 
switch. 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. SNMP is enabled by default. Consider how you want to manage the 
fabric and what switches you do not want managed or monitored through other 
switches.
3.6
Fabric Management
The SANsurfer Switch Manager application and CLI execute on a management 
workstation that provides for the configuration, control, and maintenance of 
multiple fabrics. Supported platforms include Windows, Solaris, and Linux. The 
application can be installed and executed on the workstation, or you can run the 
SANsurfer Switch Manager web applet that is resident on the switch.
Consider how many fabrics will be managed, how many management 
workstations are needed, and whether the fabrics will be managed with the CLI, 
SANsurfer Switch Manager, or the SANsurfer Switch Manager web applet.
A switch supports a combined maximum of 19 logins reserved as follows:
„
4 logins or sessions for internal applications such as management server 
and SNMP
„
9 high priority Telnet sessions
„
6 logins or sessions for SANsurfer Switch Manager inband and out-of-band 
logins, Application Programming Interface (API) inband and out-of-band 
logins, and Telnet logins. Additional logins will be refused.
