Usage Notes Terminal Loop on UNI With Multiple NNIs : A Terminal loop may be created on a UNI in an EVC with multiple NNIs. A frame received by one of the NNIs will then be looped back to all NNIs.

Type
: At the dropdown select either
Mac-Loop
or
Oam-Loop
. Note that the OAM Loop type is
currently only supported in an EVC domain.
MAC
Loop
: This TT-LOOP is the MAC looping type. All frames in the flow are looped
with MAC swap.
OAM
Loop
: This TT-LOOP is the OAM looping type. It is Y.1731 OAM aware and is
looping LBM->LBR and DMM->DMR.
Direction
: At the dropdown select either
Facility
or
Terminal
. Note that currently
Terminal
Loop is only supported in the EVC domain.
Facility
: This TT-LOOP is pointing out to the port. Looping is done from ingress to
egress.
Terminal
: This TT-LOOP is pointing into the forwarding plane. Looping is done from
egress to ingress.
Residence
Port
: The port where TT-LOOP is resident - see 'Direction'. For an EVC TT-LOOP the port must be a
port in the EVC. For a VLAN TT-LOOP the port must be a VLAN member.
Operational
State
: can be operationally Up or Down:
Up
: Instance Operational State is UP - all resources are available and allocated
Down
: Instance Operational State is DOWN - not all resources are available or administrative state is
disabled.
OpState Control
: Indicate what mechanism is controlling the operation state of this loop:
Static
: The loop is controlled by management commands (i.e., the operational state is fully controlled by
the administrative state).
Latch.LB
: The loop is controlled by the
MEF 46
Latching Loopback (LL) protocol. The administrative state
can control whether the loop responds to LL PDUs but the loop will only enter the active state if a valid
LLM Activate PDU is received from a remote host.
Buttons
Add New TT-LOOP
: Click to add a new TT-LOOP entry.
Refresh
: Click to manually refresh the page immediately.
Apply
: Click to save changes. Only one TT-LOOP can be added for each Save operation.
Reset
: Click to undo any changes made locally and revert to previously saved values.
Usage Notes
Terminal Loop on UNI With Multiple NNIs
: A Terminal loop may be created on a UNI in an EVC with multiple
NNIs. A frame received by one of the NNIs will then be looped back to all NNIs. If this behavior is not desired, you
can avoid this by creating static MAC table entries that direct the looped frames to the desired port.
