portSecurityAdminStatus 1.3.6.1.4.1.9.5.1.10.1.1.3

When security is enabled, source MAC addresses are monitored for all packets received on the port. If an address is detected that does not match the portSecuritySecureSrcAddr and any corresponding portSecurityExtSecureSrcAddr, of which portSecurityExtModuleIndex and portSecurityExtPortIndex in the portSecurityExtTable is the same as the portSecurityModuleIndex and portSecurityPortIndex, and the number of MAC address learned or configured for this port is equal to portSecurityMaxSrcAddr, the port will shutdown or drop packets. If the portSecurityViolationPolicy is set to shutdown(2), the port is shutdown and a linkDown trap is sent; otherwise the port drops the invalid packets.
