CPAM parameters
Destination FEC
The Destination FEC parameter specifies the IP address and subnet mask of the destination router or link in a CSPF calculation. Enter an IPv4 address in dotted decimal format or use the Select button to list and choose a destination router or link.
Ethernet Error
The Ethernet Error parameter specifies whether the audit verifies the error rate of the IP link against a specified threshold. The options are:
First IP
The First IP parameter specifies the IP address of the source router. Enter the IPv4 address of the router in dotted-decimal format or use the Select button to list and choose a router.
Group IP
The Group IP parameter specifies the IP address of a multicast group to be highlighted.
In Profile Drop
The In Profile Drop parameter specifies whether the audit verifies the in profile drop rate for FC queues 1 to 8 against a specified threshold. The options are:
Interface Error
The Interface Error parameter specifies whether the audit verifies the error rate of the network interface against a specified threshold. The options are:
Least Fill Min Threshold %
The Least Fill Min Threshold % parameter specifies the minimum threshold of least-utilized links that can be used in the ECMP tie-breaking process.
The Least Fill Min Threshold % parameter is configurable only when the Request Type parameter is set to Least_Fill.
Line - Severely Errored Seconds
The Line - Severely Errored Seconds parameter specifies whether the audit verifies the counter associated with the number of severely errored framing seconds found by a SONET/SDH line in the current 15 minute interval. The options are:
Mask
The Mask parameter specifies the subnet mask length for the multicast group prefix. This parameter works in conjunction with the Multicast Group Prefix parameter. The range is 0 to 32. The default is 0.
Multicast Group Prefix
The Multicast Group Prefix parameter specifies the prefix for a multicast group.
Out of Profile Drop
The Out of Profile Drop parameter specifies whether the audit verifies the out of profile drop rate for FC queues 1 to 8 against a specified threshold. The options are:
Prefix Length
The Prefix Length parameter, when combined with an IP address value, specifies the local IP prefix. The range is 0 to 32. The default is 24.
Protocol
The Protocol parameter specifies the multicast protocol of the routers to be highlighted. The options are:
Request Type
The Request Type parameter specifies how CSPF selects a path in the tie-breaking process for ECMP if there are several equal cost paths. The parameter options are described in the following table:
Table A-44: Request Type parameter
Option |
Description |
Dependencies |
---|---|---|
All |
Traffic is sent over all of the matching paths. |
— |
Random |
Traffic is sent over one randomly selected path. |
— |
Least_Fill |
Traffic is sent over the path with the least-utilized links. The CPAM considers the value of the Least Fill Min Threshold % only when this option is selected. |
— |
Required Bandwidth
The Required Bandwidth parameter specifies the minimum available bandwidth of the calculated CSPF. The range is 0, or 1 to 4 294 967 295. A value of zero means that the CSPF calculation includes no minimum bandwidth requirements.
Second IP
The Second IP parameter specifies the IP address of the destination router. Enter the IPv4 address of the router in dotted-decimal format or use the Select button to list and choose a router. On an ISIS topology map, an IPv6 router address can be entered in colon-hexadecimal format.
Section - Severely Errored Framing Seconds
The Section - Severely Errored Framing Seconds parameter specifies whether the audit verifies the counter associated with the number of severely errored framing seconds found by a SONET/SDH section in the current 15 minute interval. The options are:
Section - Severely Errored Seconds
The Section - Severely Errored Seconds parameter specifies whether the audit verifies the counter associated with the number of severely errored seconds found by a SONET/SDH section in the current 15 minute interval. The options are:
Source IP
The Source IP parameter specifies the IP address of the source router or link in a CSPF calculation. Enter an IPv4 address in dotted decimal format or use the Select button to list and choose a source router or link.
SRLG Strict
The SRLG Strict parameter specifies whether the CSPF highlight is calculated if the CPAM does not find path with SRLG. If the SRLG Strict parameter is enabled, CSPF tries to find paths with excluded SRLG. If no paths are found, CSPF returns an empty result.
If the SRLG Strict parameter is disabled, CSPF tries to find paths with excluded SRLG. If no paths are found, CSPF returns paths that ignore the SRLG constraint, if any.
The options are:
SRLG Value
The SRLG Value parameter specifies the SRLG value that must be excluded from a CSPF calculation. The range is 1 to 4 294 967 295.
Stats Capture Delay
The Stats Capture Delay parameter specifies the delay, in seconds, between first capture and the second capture of the statistics. The range is 15 to 300. The default is 30.
Total Drop
The Total Drop parameter specifies whether the audit verifies the drop rate for FC queues 1 to 8 against a specified threshold. The options are:
Threshold
The Threshold parameter specifies the threshold against which the audit parameter is compared. The files that enable customization of the default Threshold values can be found in /opt/nsp/nfmp/server/nms/config/audit/params on an NFM-P main server. The following table lists the defaults for each audit parameter:
