hcxStuEthTestAction

Module: COM21-HCXSTU-MIB

OID (symbolic): COM21-HCXSTU-MIB::hcxStuEthTestAction

OID (numeric): 1.3.6.1.4.1.1141.2.51.1.1.17

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This attribute is used to invoke the ComPort Ethernet test. If lpBkTest is selected, the ComController will place the ComPort in the loopback state, transmit a number of ethernet packets and validate the returned packets. hcxStuEthLpbkTestUpRate and hcxStuEthLpbkTestLatency attributes contain the Rate and Latency for the upstream path If dnStrmTest is selected, the ComController will transmit a number of ethernet packets and calculate the downstream rate. hcxStuEthTestDnRate attribute will contain the rate for the downstream path.

What is hcxStuEthTestAction?

This read-write INTEGER selects nil, lpBkTest, or dnStrmTest to invoke an Ethernet test on the ComPort, with the description explaining lpBkTest places the device in loopback and measures rate/latency (recorded in hcxStuEthLpbkTestUpRate and hcxStuEthLpbkTestLatency) while dnStrmTest measures a different downstream path. An admin uses this to actively test the Ethernet path quality to a subscriber's device on demand. For example, when a customer complains about slow file transfers, the admin sets hcxStuEthTestAction to lpBkTest(2) to measure actual upstream loopback rate and latency to that ComPort.
