Solving Problems With an SNMP Network
Management Application
The SNMP network management application
cannot access the stack.
Check that:
■
The switch’s IP address, subnet mask and default
router are correctly configured and that the switch
has been reset since configuring this information;
refer to
“Displaying the IP Configuration”
on
■
The switch’s IP address is correctly recorded by the
SNMP management application. For information on
how to do this, refer to the documentation
accompanying the application.
The SNMP network management application can
no longer access the switch.
Check that the port
through which you are trying to access the switch has
not been disabled. If it is enabled, check the
connections and network cabling at the port. Try
accessing the switch through a different port. If you
can now access the switch, 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 switch over the network. Try
accessing the switch through its console port and
reset the switch.
