Solving Problems With an SNMP Network Management
Application
The SNMP network management application cannot access
the stack. Check that:
■
The stack’s IP address, subnet mask and default router are
correctly configured, using either:
■
The command line interface — refer to
“Displaying the IP
Information”
on
page 52
.
■
The web interface — refer to
“Management Address”
on
page 85
.
■
The stack’s IP address is correctly recorded by the management
application. For information on how to do this, refer to the
documentation that accompanies the application.
■
You can access other devices. If you cannot access any other
devices, there may be a problem with your SNMP network
management application or management station.
The SNMP network management application can no longer
access the stack. Check that the port through which you are trying
to access the stack has not been disabled. If it is enabled, check the
connections and network cabling at the port. Try accessing the stack
through a different port. If you can now access the stack, a problem
with the original port is indicated. Re-examine the connections and
cabling.
Possibly there is a network problem preventing you from accessing
the stack over the network. Try accessing the stack through the
console port of one of the hubs, and reset the stack.
