Use the Protection subtab to provision protection for the GE_XP, 10GE_XP, GE_XPE, and 10GE_XPE
cards. The following table describes the Protection subtab page fields and buttons.
|
|
|
Displays the card port number. The GE_XP is a double-slot card with twenty GE client ports (displayed as ONE_GE) and two 10GE trunk ports (displayed as TEN_GE).
|
|
Sets the Spanning Tree Protocol (STP) port states. If you have designated the card as a master, you must set one of the trunk ports to the blocked state to avoid loops in the network.
• |
Blocking —Sets the port in the blocked (standby) state. A port in the blocking state does not participate in frame forwarding. |
• |
Forwarding —Sets the port to the forwarding state. A port in the forwarding state forwards frames. |
|
|
Displays the current STP port states.
|
|
If checked clears DATA-CRC alarm
|
|
Sets the card as the master card for the network. Only one card in the network should be set as a master card.
|
|
• |
Enabled —Enables protection. |
• |
Disabled —Disables protection |
• |
Forced —Forces the protection. |
|
|
If enabled, the LOS will be activated in FAPS state machine only after the hold off time.
|
|
Retrieves the current protection status.
|
|
If checked, enables switch with CRC alarm is raised
|
|
Configures CRC error rate as a percentage of the traffic. The following error rates are available:
• |
10e-2 pr 1% of traffic(1 CRC error in 100 packets) |
• |
10e-3 pr .1% of traffic(1 CRC error in 1000 packets) |
• |
10e-4 pr .01% of traffic(1 CRC error in 10000 packets) |
|
|
Indicates the state machine soak before declaring excess CRC error. If the threshold is crossed by CRC error count in N consecutive intervals, excessive CRC error is declared. The values of N is from 3 to 10. Default value is 10.
|
|
Configures the detection module in state machine managed by timer in alarm agent with frequency of 60 seconds. The value ranges from 10 to 60 sec, default value is 60.
|
|
Applies changes made to the protection.
|
|
Cancels any changes to the protection and returns it to its last-saved settings.
|
|
Displays context-sensitive help.
