Module: NEXANS-BM-MIB

OID (symbolic): NEXANS-BM-MIB::portSecurityMacAddr1

Description: The first MAC address used for port security. If portSecurityAdminState has the value disable(2), portSecurityManualSettingMacAddr(3) or vendorSettingMacAddr(12) then this object will be read-write. In any other mode this object will be read-only and shows the first automatically learned MAC addresses for that port.

What is portSecurityMacAddr1?

Holds the first MAC address enforced or learned for port security on this port; it's writable only when portSecurityAdminState is disable(2), manualSettingMacAddr(3), or vendorSettingMacAddr(12) - in any other mode it's read-only and simply shows the first address the switch learned automatically.
