For RG Mode this MIB provides a way to force the ifAdminStatus.x MIB settings for the individual Ethernet ports to the values stored in cmEthernetAdminStatus.x. This feature is activated by setting cmEthernetIfAdminOverride is set to enable(1). Bridge mode is a special case since there is only one ifindex = .1 for all 4 ports. In Bridge Mode this MIB still allows you control the port status per Ethernet interface. However, the value of ifAdminStatus.1 and ifOperStatus.1 will follow the following logic: If at least 1 port is set to up by cmEthernetIfAdminStatus.x then ifAdminStatus.x will be set to up(1). If all ports are set to down by cmEthernetIfAdminStatus.x then ifAdminStatus.1 will report down(2). ifAdminStatus.x will report testing(3) if all ports set by cmEthernetIfAdminStatus.x are in testing(3) status. The major use case for this MIB is to set specific unused ports on the RG to down(2) status immediately after a reboot and prior to CM registration. This MIB is written to non-vol and survives a reboot. A factory reset sets MIB index values back to up(1). 1: up(1) Force the individual port to up(1). 2: down(2) Force the individual port to down(2) 3: testing(3) Force the port to testing status(3) No packets passed.
