Fabric services security includes SNMP and In-band management. Simple 
Network Management Protocol (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 basically 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 using the 
SNMP Properties dialog. 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. Refer to 

 for 

more information. SNMP is enabled by default.

In-band management is the ability to manage switches across inter-switch links 
using SANsurfer Switch Manager, SNMP, management server, or the application 
programming interface. The switch comes from the factory with in-band 
management enabled. If you disable in-band management on a particular switch, 
you can no longer communicate with that switch by means other than a direct 
Ethernet or serial connection. Refer to 

 for more information.

1.

On the faceplate display, open the Switch menu and select SNMP 
Properties to open the SNMP Properties dialog.

2.

In the SNMP Configuration area, place a check mark in the SNMP Enabled 
check box.

3.

Click the OK button to save the change to the database.

To enable In-band Management, do the following:

1.

On the faceplate display, open the Switch menu and select Switch 
Properties to open the Switch Properties dialog. 

2.

Click the In-band Management Enable button. 

3.

Click the OK button to save the change to the database.
