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, refer to “Giving the Stack an IP Address” on pa ge B-9.
■The stack has been reset.
■The stack’s IP address is correctly recorded by the management
application. For in formation on how to do th is, refer to the
documentation accompanying the application.
■SNMP Access has not been disabled for the access level you are
using to manage the stack. Use the Access Informa tion panel of
the General Info dialog box in Quick Conf ig Manager, refer to
Appendix B.
■For management communication to wo rk over the network, the
port through which your communication reaches the stac k must be
connected to segment 1 (either direct ly or indirectly) of the hub with
the IP address configured. For information, refer to “Requireme nts
for Managing Over the Network” on pag e 5-6.
Traps are not received by the SNMP network managem ent
application. Check that the address of the management station is
entered in the stack. You can do this using Quick Config Ma nager;
refer to “Giving the Stack an IP Address” on page B-9.
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 po rt. Try accessing the stack
through a different port. If you can now access the stack, a problem
with the original port is indicated, or it ha s been switched from
segment1 to another segment. 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.
If you still cannot access the hub, use the A ccess Information panel of
the General Info dialog box in Quick Config Manager to check if SNMP
access is enabled, refer to Appendix B.
