port has been detected by the physical layer.
The port is enabled.
- in-service: the remote device successfully acknowledges
ILMI polling requests and SVC registration
- pvcOnly: the remote device succesfully acknowledges
ILMI polling requests but it rejects the ATM
prefix registration. Only PVCs are supported.
- misConfigured: an SSI to UNI or an SSI to NNI configuration
has been detected
- wrongNetworkPrefix: the switches on each end of an SSI link
have incompatible network prefixes (the
12 first bytes have different values)
- wrongNodeNumber: the switches on each end of an SSI link
have the same ATM node Numbers.
- failing-line: the port is enabled and a invalid
signal is detected on the line
- disabled-failing: the port is disabled and an
anomaly is detected, either internal
or external.
- wrap-no-signal: the port is internally wrapped so that
all the traffic received on the attached line is
returned unchanged on the line.
No activity is detected at the physical
layer.
- wrap-idle: the port is internally wrapped so that
all the traffic received on the attached line is
returned unchanged on the line and
a valid signal is detected on the line.
- wrap-failing-internal: an internal failure has been
detected when the port has been
turned into the wrap-reply state.
The actual state of the port is
undefined.
- wrap-failing-line: the port is internally wrapped so that
all the traffic received on the attached
line is returned unchanged on the line
and an invalid signal is detected
on the line.
- idle-no-bandwidth: the port is enabled and activity
from the remote device is detected but
there is not enough bandwidth to operate
the port with its current configuration.
This state does not apply for UNI port.
- idle-internal-error: The port is enabled and activity
from the remote device is detected but
an internal error has occurred during
the checking of the bandwidth configuration.
This may be due to a lack of connection
ressources in the module where this port is
located.
- disabled-no-bandwidth:
the enabling of the port is not
possible because
there is not enough bandwidth to operate
the port with its current configuration.
This state applies only for a SSI port.
- wrap-far-end-no-signal:
the port is in wrap-far-end
mode, ie the remote end of the line is
