Transition Networks SISPM1040-3xxx-L Web User Guide Common Parameters Profile Name : Each profile must have a name that uniquely identifies it, since it is this name that is used in the process of executing a profile. The length must be 1 to 32 characters with each ASCII character being in the range 33 - 126 except for and \' characters. Description : This field allows for providing a textual description of the profile. Up to 128 characters can be entered with each ASCII character being in the range 32 - 126. DST is OAM-aware : The frame types used in the RFC2544 tests are Y.1731 OAM. This field selects between using TST/1DM (when 'DST is OAM-aware' is un-checked) and LBM/DMM (when 'DST is OAM-aware' is checked). In the first case, it is expected that the frames returned by the remote end are of the same type as the ones transmitted by this end (i.e., TST/1DM), whereas in the latter case, it is expected that the frames returned by the remote end are of type LBR/DMR. MEG Level : The frame types used in the various tests are Y.1731 OAM frames (See 'DST is OAM-aware' for actual type). These frame types contain a MEG Level (MEL) field, which can be controlled with the value entered in this select box, which ranges from 0 to 7 with 7 being the default. Egress Port : The port on which the generated frames are transmitted and expected received. Sequence Number Check : When checked, looped Y.1731 TST/LBR frames are tested for out-of-order upon reception. Out-of-order frames are frames received in a different order than they were transmitted. If an out-oforder sequence is detected, the sub-test or trial is considered failing. Dwell Time : When a trial is executed, Y.1731 TST or LBM frames are transmitted for a certain period of time. When that period has elapsed, the Dwell Time defines how long to wait before reading hardware counters and status in order to assess the status of the trial. The required dwell time must be at least the worst-case roundtrip time, and therefore depends on the physical distance between the near and far ends. Valid range is 1 - 10 with a default of 2 seconds. Type : The RFC2544 test suite supports two types of tagging of frames on egress: Port Down-MEP, where all frames are transmitted untagged. VLAN-based Down-MEP, where all frames are transmitted with a VLAN tag. In order for this to work, the following manual VLAN configuration of the egress port is required: o The VLAN Port Mode must be Trunk or Hybrid in order to get frames tagged upon transmission. o The VLAN Port Type must be either C-, S-, or S-Custom. o VLAN Egress Tagging must be set to either tag all or untag Port VLAN. In the latter case the chosen VLAN ID for the profile must be different from the configured VLAN Port VLAN ID. o The port must be member of the chosen VLAN ID. o Whichever type is selected, frames are generated as close to the egress port as possible (hence the "Down-MEP" term) and therefore are not sent through the queueing system, due to lack of integration with EVCs in this version of the software. When VLAN-based Down-MEP is selected, the VLAN tag's ID, PCP, and DEI values are selected with the subsequent fields. 33763 Rev. G https://www.transition.com Page 429 of 496
