Cisco Switch-port Information Is Not Showing
============================================

Symptom
-------

Switches are visible but but the switch ports are not visible in node
management, node info or the switch management views.

Cause
-----

If using SNMPv3 , some IOS versions may require you to configure the
snmp-server group to view all contexts you wish to monitor.

Resolution
----------

In this example, the SNMP group used to gain switch visibility is not
authorized to view the VLANs assigned to the switch ports. To gain visibility
of the switch ports, the group must be given privilege for the contexts.
(VLANs)
