Description
This article describes although the Polling tab for a switch in Topology shows L2 Polling is successful, the Ports View does not display hosts that are currently connected to certain ports. This can occur if the affected ports have the Secure Ports feature enabled.
The Secure Port feature only allows communication for certain MAC addresses. This is typically done using static MAC Address entries.
Example of switch output when Secure Ports feature is not enabled:
0008.e3ff.fd90 DYNAMIC
0009.0f09.0017 DYNAMIC
000a.f779.e3fe DYNAMIC
Example when Secure Ports is enabled:
0008.e3ff.fd90 STATIC
0009.0f09.0017 STATIC
000a.f779.e3fe STATIC
By default, static MAC Addresses are not read from the MAC Address table of a switch. Hosts connected to ports configured for Secure Port will not be detected unless the additional configuration is completed.
