Step 2. Wait for the GetResponse PDU. If the port is not disabled (refer to
ifOperStatus), then a generic link down trap PDU may be generated.
Step 3. If the GetResponse did not indicate an error, then wait for (and
acknowledge) the enterprise specific trap that contains the
lpbkOperation parameter. [Multiple traps may be sent if there are
multiple errors.]
To put a port into remote loopback, the NMS must perform the following steps
Step 1. Set the lpbkPktLength, lpbkPktNum, lpbkIncrements, lpbkInterval,
lpbkDestAddr, and lpbkOperation parameters with a single SetRequest
PDU, making sure that lpbkOperation is the last parameter. The value
loopback-remote must be specified for lpbkOperation, and the previous
value for lpbkOperation must not be loopback-local. Also, the port must
be enabled according to ifOperStatus.
Step 2. Wait for the GetResponse PDU.
Step 3. If the GetResponse did not indicate an error, then wait for (and
acknowledge) the enterprise specific trap that contains the
lpbkOperation parameter. (Multiple traps may be sent if there are
multiple errors.)
A port’s loopback operation is automatically terminated after the requisite
number of packets have been sent. To immediately terminate a port’s loopback
operation, the NMS may perform the following steps:
Step 1. Issue a SetRequest PDU, specifying the value loopback-off for lpbkOp-
eration.
Step 2. Wait for the GetResponse PDU. If the port was in local loopback, then
the port will be automatically re-enabled to the extent specified by the
current value of sprotoEntry for that port.
lpbkTable
{lpbk 1}
Not-Accessible
A list of interface entries; one per port.
lpbkEntry
{lpbkTable 1}
Not-Accessible
A set of objects for an interface entry. The individual components are described
below.
