Port
|
The PPM number.
|
Port Name
|
Name for the optical port.
|
Admin State
|
Shows the administrative state of the port. Choosing an administrative state from the drop-down list and clicking Apply changes the port's service state unless network conditions prevent the change. Admin states include:
IS-Puts the port in-service. The port service state changes to IS-NR.
OOS,DSBLD-Removes the port from service and disables it. The port
service state changes to OOS-MA,DSBLD.
OOS,MT-Removes the port from service for maintenance. The port service
state changes to OOS-MA,MT.
|
Service State
|
An autonomously generated state that gives the overall condition of the port. Service states appear in the format: Primary State-Primary State Qualifier, Secondary State. Port service states include:
IS-NR-(In-Service and Normal) The port is fully operational and
performing as provisioned.
OOS-MA,DSBLD-(Out-of-Service and Management, Disabled) The port is
out-of-service and unable to carry traffic.
OOS-MA,MT-(Out-of-Service and Management, Maintenance) The port is
out-of-service for maintenance. Alarm reporting is suppressed, but traffic is
carried and loopbacks are allowed.
|
Link State
|
The physical port state. Possible values are Up and Down.
|
Enable Flow Control
|
If checked, enables the IEEE 802.3x flow control and buffering to reduce data congestion on the port (default). If flow control is enabled, the port must be set to autonegotiation. If flow control is enabled but the negotiation status indicates no flow control, check the autonegotiation settings.
|
Flow Control
|
The negotiated flow control mode. Possible values are None, Symmetrical, and Asymmetrical.
|
Enable Auto Negotiation
|
If checked, sets the port for autonegotiation. To enable flow control, the port must be set to autonegotiation.
|
Max Size
|
Sets the maximum Ethernet frame size:
9600: Sets the maximum Ethernet frame size at 9600 bytes.
1548: Sets the maximum Ethernet frame size at 1548 bytes. This size enables
the port to accept valid Ethernet frames that use protocols, such as
Inter-Switch Link (ISL). ISL adds 30 bytes of overhead and may cause the
frame size to exceed the traditional 1518 byte maximum.
|
Flow Control Lo
|
Shows the low flow control buffer level for the water marks setting. Type the desired low flow control buffer level.
|
Flow Control Hi
|
Shows the high flow control buffer level for the water marks setting. Type the desired high flow control buffer level.
|
Apply
|
Applies changes made to the fields in the tab.
|
Reset
|
Cancels any changes to the tab and returns the fields to their last-saved settings.
