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.
