The POS Ports subtab displays ONS 15600 SDH ASAP card packet-over-SDH (POS) port information.
The POS Ports subtab options are described in the following table.
|
The port identifier number.
|
|
|
|
Shows the administrative state of the port. Choose an administrative state from the drop-down list and click Apply to change the port service state unless network conditions prevent the change. Administrative states include:
• |
unlocked: Puts the port in service. The port service state changes to unlocked-enabled. |
• |
locked,disabled: Removes the port from service and disables it. The port service state changes to locked-enabled,disabled. |
• |
locked,maintenance: Removes the port from service for maintenance. The port service state changes to locked-enabled,maintenance. |
• |
unlocked,automaticInService: Puts the port in automatic in-service. The port service state changes to unlocked-disabled,automaticInService. |
Note |
CTC will not allow you to change a port service state from unlocked-enabled to locked-enabled,disabled. You must first change a port to the locked-enabled,maintenance service state before putting it in the locked-enabled,disabled 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. For additional state information, see States.
|
|
Shows the encapsulation type set on the Card subtab:
• |
HDLC —High-level data link control. Does not support VLAN trunking, which is standard on most Cisco data devices. |
• |
GFP-F —Frame-mapped generic framing procedure; a protocol data unit (PDU)-oriented adaptation mode that maps a client frame into one GFP frame. |
• |
X.86 —Link access procedure (LAP), an HDLC-like framing structure to encapsulate IEEE 802.3 Ethernet frames. |
|
|
Sets the cyclic redundancy check (CRC) to verify the integrity of the transmitted data. Possible values are:
• |
16-Bit or 32-Bit for HDLC |
|
|
The physical port state. Possible values are Up and Down.
|
|
Maximum transfer unit. The largest acceptable packet size configured for that port. The maximum setting is 9000 and the default size is 1500. The MTU value is 0 until the POS port is used in creating a circuit.
|
|
Applies changes made to the port name.
|
|
Cancels any changes to the port name and returns the field to its last-saved settings.
|
|
Displays context-sensitive help.
