Configuring SNMP
Settings
The following SNMP parameters can be configured on the Switch:
■
Authorized trap receivers — An authorized trap receiver can be
one or more network management stations on your network. The
Switch sends SNMP traps to the trap receiver. You can have a
maximum of six trap receivers configured for each Switch 9000.
■
Community strings — The community strings allow a simple
method of authentication between the Switch and the remote
Network Manager. There are two community strings on the Switch
9000. The read community string provides read-only access to the
Switch. The default read community string is
public . The write
community string provides read and write access to the Switch. The
default write community string is
private . The community string for
all authorized trap receivers must be configured on the Switch in
order for the trap receiver to receive Switch-generated traps.
■
System contact (optional) — The system contact is a text field that
allows you to enter the name of the person(s) responsible for
managing the Switch.
■
System name — The system name is the name that you have
assigned to this Switch. The default name is 3C16990.
■
System location (optional) — Using the system location field, you
can enter a location for this Switch.
Table 3-4 describes SNMP configuration commands.
