prptrSecurityPortDAMismatch
Module: Hub-rptr-prvt-sec
OID (symbolic): Hub-rptr-prvt-sec::prptrSecurityPortDAMismatch
OID (numeric): 1.3.6.1.4.1.22.101.8.6.1.1.8
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: When this variable is set to enable(2) the port employs destination address comparison to implement security, meaning that whenever a packet needs to be send to the port, the destination address of the packet is compared and if it does not match one of the MAC entries then DA mismatch is detected. If a DA mismatch is detected, and the object prptrSecurityGroupRandomMode is set to enable(2) then a random sequence is sent to that port. if the destination address matches one of the port MAC entries then the packet is transmitted to the port without modification.
When this variable is set to disable(3) the port does NOT employ destination address comparison to implement security.
The value other(1) is returned whenever the DA mode is unknown. This value should not be written into the agent.
What is prptrSecurityPortDAMismatch?
This read-write field enables or disables destination-address comparison security on this port: when enabled, an outgoing packet whose destination doesn't match one of the port's MAC entries triggers a DA mismatch, and if prptrSecurityGroupRandomMode is also enabled a random sequence is sent to the port instead. An admin enables this to prevent a device on this port from receiving traffic addressed to any MAC other than its own.
