The redundancy mode of the port. The values when written change the redundancy mode, and when read report the redundancy mode: standalone(1)..the port is not in any redundant pair. hwActive(2)....the port is the active companion in a hardware-redundant pair. hwStandby(3)...the port is the standby companion in a hardware-redundant pair. swActive(4)....the port is the active companion in a software-redundant pair. swStandby(5)...the port is the standby companion in a software-redundant pair. The values that can be written, which change the redundancy mode, are: standalone(1)...causes the redundant pair to be broken up. hwActive(2).....if the previous value was hwStandby(3), this value will cause the port to become the active port in the hardware-redundant pair, resulting in a switchover. hwStandby(3)....if the previous value was hwActive(2), this value will cause the port to become the standby port in the hardware-redundant pair, resulting in a switchover. swActive(4).....if the previous value was swStandby(5), this value will cause the port to become the active port in the software-redundant pair, resulting in a switchover. swStandby(5)....if the previous value was swActive(4), this value will cause the port to become the standby port in the software-redundant pair, resulting in a switchover. To create a hardware-redundant pair, change this object to hwActive(2) or hwStandby(3). To create a software-redundant pair, change this object to swActive(4) or swStandby(5). The same SNMP SET PDU must also write to objects s5EnRedPortCompanionBrdNum and s5EnRedPortCompanionPortNum.
