Changing an IPSG M2PA Linkset

This procedure is used to change an IPSG M2PA linkset, a linkset that contains the IPSG value yes and whose ADAPTER value is m2pa, in the EAGLE using the chg-ls commands with these parameters.

:lsn – The name of the linkset that will be changed, shown in the rtrv-ls output.

:ipsg – This parameter specifies whether or not the linkset is an IPSG linkset. This parameter has two values, yes (if the linkset is an IPSG linkset) or no (if the linkset is not an IPSG linkset). For this procedure, the ipsg parameter value must be yes.

:maxslktps – The maximum number of transactions per second (TPS) for all signaling links that are assigned to the IPSG M2PA linkset. See Maximum Card Capacity for Different Card Types for MaxTPS values.

:rsvdslktps – The number of transactions per second (TPS) that is assigned to each IPSG signaling link that will be in the linkset. See Maximum Card Capacity for Different Card Types for MaxTPS values. The slktps parameter can be used in place of the rsvdslktps parameter.

:tpsalmtype – The TPS threshold that will generate alarms. This parameter has two values.

rsvdslktps - The RSVDSLKTPS threshold generates alarms.
maxslktps - The MAXSLKTPS threshold generates alarms.

:adapter - This parameter specifies the adapter layer for the signaling links that will be assigned to the IPSG M2PA linkset. This parameter has two values, m2pa and m3ua. For an IPSG M2PA linkset, the adapter parameter value must be m2pa.

:lsusealm – The linkset’s TPS alarm threshold, from 10 to 100 percent of the linkset’s TPS. When this threshold is reached, a major alarm (UAM 0115) is generated. When the linkset’s TPS falls below this threshold, UAM 0115 is automatically cleared and UAM 0118 is generated.

:slkusealm – The signaling link TPS alarm threshold, from 10 to 100 percent of the signaling link’s fair share of the linkset’s TPS or from 10 to 100 percent of the IPSG card’s capacity. See Maximum Card Capacity for Different Card Types for MaxTPS values. This threshold is reached when the signaling link’s actual usage exceeds the percentage of the signaling link’s fair share of the linkset’s TPS or the percentage of the IPSG card’s capacity.

A signaling link's fair share of linkset’s TPS is the linkset’s TPS divided by the number of in-service links in the linkset. For example, if the linkset TPS is 4000 and there are 4 signaling links in the linkset, all in-service, then the signaling link's fair-share would be 1000 TPS (4000/4=1000). Table 6-10 shows this calculation for a linkset with 1, 2, 3 and 4 in-service signaling links.

Table 6-10 Signaling Link Fair Share Example

Number of In-Service Signaling Links	Linkset TPS	Signaling Link Fair Share of the Linkset TPS
4	4000	1000
3	4000	1333
2	4000	2000
1	4000	4000

When this threshold is exceeded, a minor alarm (UAM 0116) is generated. When the amount of traffic on the signaling link falls below this threshold, UAM 0116 is automatically cleared and UAM 0119 is generated.

The signaling link TPS alarm shows that the linkset TPS is set too low for the linkset or that the IPSG card's capacity has been exceeded. Setting the signaling link TPS alarm threshold lower than the linkset TPS alarm threshold can give the user an earlier indication that the linkset TPS is inadequate or that traffic is not balanced across the links in the linkset.

Changing the MAXSLKTPS or RSVDSLKTPS values for the IPSG M2PA linkset cannot exceed the maximum total provisioned system TPS shown in the rtrv-tps output. If changing the IPSG M2PA linkset will exceed the maximum total provisioned system TPS, and the maximum total provisioned system TPS is 500,000, perform the "Activating the HIPR2 High Rate Mode" feature in Database Administration - System Management to enable and turn on the HIPR2 High Rate Mode feature. When the HIPR2 High Rate Mode feature is enabled and turned on, the maximum total provisioned system TPS is increased to 1,000,000 (1M). If the maximum total provisioned system TPS is 1M or the maximum total provisioned system TPS is 500,000 and will not be increased, and changing the MAXSLKTPS or RSVDSLKTPS values for the IPSG M2PA linkset will exceed the maximum total provisioned system TPS, the MAXSLKTPS or RSVDSLKTPS values for the IPSG M2PA linkset cannot be changed unless the amount of available TPS is reduced enough to allow the MAXSLKTPS or RSVDSLKTPS values for the IPSG M2PA linkset to be changed. The available TPS can be reduced by performing one or more of these actions.

The IP TPS values of some IPGWx linksets have to be changed.
The MAXSLKTPS values of some IPSG linksets (and the RSVDSLKTPS values if necessary) have to be changed.
Some ATM high-speed signaling links have to be removed.
An IPLIMx card that contains signaling links has to be removed.

This procedure can also be used to change an IPSG M3UA linkset or a non-IPSG linkset to an IPSG M2PA linkset.

Other Optional Parameters

There are other optional parameters for an IPSG M2PA that can be changed. These parameters are not required for IPSG M2PA linkset. These parameters are discussed in more detail in Commands User's Guide or in these sections.

These procedures in this manual:

Canceling the RTRV-LS Command

Because the rtrv-ls command used in this procedure can output information for a long period of time, the rtrv-ls command can be canceled and the output to the terminal stopped. There are three ways that the rtrv-ls command can be canceled.

Press the F9 function key on the keyboard at the terminal where the rtrv-ls command was entered.
Enter the canc-cmd without the trm parameter at the terminal where the rtrv-ls command was entered.
Enter the canc-cmd:trm=<xx>, where <xx> is the terminal where the rtrv-ls command was entered, from another terminal other that the terminal where the rtrv-ls command was entered. To enter the canc-cmd:trm=<xx> command, the terminal must allow Security Administration commands to be entered from it and the user must be allowed to enter Security Administration commands. The terminal’s permissions can be verified with the rtrv-secu-trm command. The user’s permissions can be verified with the rtrv-user or rtrv-secu-user commands.

For more information about the canc-cmd command, go to Commands User's Guide.

Display the current linksets in the database using the rtrv-ls command.

This is an example of the possible output.

Link set table is (13 of 1024) 1% full.

Display a linkset shown in 1 by entering the rtrv-ls command with the name of the linkset shown in 1. For this example, enter these commands.
rtrv-ls:lsn=lsgw1101

This is an example of the possible output.

If you do not wish to change this linkset, choose another linkset from 1 and repeat this step.
If this linkset will be changed, perform one of these steps.
- If the IPGWAPC value of the linkset is yesor if the IPGWAPC and IPSG values of the linkset are no, the linkset must be removed from the database and then an IPSG M2PA linkset must be added. Perform the "Removing a Linkset Containing SS7 Signaling Links" procedure in Database Administration - SS7 User's Guide to remove the linkset. After the linkset has been removed, perform the Adding an IPSG M2PA Linkset procedure to add the IPSG M2PA linkset. After the IPSG M2PA linkset has been added, perform the Adding an IPSG M2PA Signaling Link procedure to add IPSG M2PA signaling links to the new IPSG M2PA linkset. This procedure is finished.
- If the IPSG value of the linkset is yes, continue the procedure with one of these steps.
  - If the ADAPTER value of the linkset is M3UA, perform the Adding an IPSG M3UA Signaling Link procedure to remove the IPSG M3UA signaling links from the linkset. After the IPSG M3UA linksets have been removed from the linkset, continue the procedure with 3.
  - If the ADAPTER value of the linkset is M2PA, continue the procedure with one of these steps.
    
    If the RSVDSLKTPS value of the linkset will not be changed, continue the procedure with 5 .
    
    If the RSVDSLKTPS value of the linkset will be changed, continue the procedure with 4.
Change the ADAPTER value of the linkset to M2PA by entering the chg-ls command with the adapter=m2pa parameter and the name of the linkset that is being changed. For this example, enter this command.
chg-ls:lsn=lssg1101:adapter=m2pa

When the chg-ls command has successfully completed, this message should appear.

After the ADAPTER value of the linkset has been changed, continue the procedure by performing one of these steps.
- If the RSVDSLKTPS value of the linkset will not be changed, continue the procedure with 5.
- If the RSVDSLKTPS value of the linkset will be changed, continue the procedure with 4.
The new RSVDSLKTPS value for the linkset cannot allow the sum of the TPS used by all the IPSG signaling links that are assigned to each IPSG card shown in the linkset to exceed the MaxTPS (see Maximum Card Capacity for Different Card Types for MaxTPS values) and cannot exceed the maximum total provisioned system TPS.
To verify the TPS for the IPSG cards containing the IPSG signaling links in the linkset, enter the rtrv-slk command with the card location of each signaling link that is assigned to the linkset. For this example, enter these commands.

An IPSG M2PA linkset uses MAXSLKTPS (see Maximum Card Capacity for Different Card Types for MaxTPS values), as provisioned by the maxslktps parameter. If adding the new IPSG M2PA linkset will not exceed the maximum total provisioned system TPS, continue the procedure with 11.

If adding the new IPSG M2PA linkset will exceed the maximum total provisioned system TPS, and the maximum total provisioned system TPS is 500,000 shown, perform the "Activating the HIPR2 High Rate Mode Feature" procedure in Database Administration - System Management User's Guide to enable and turn on the HIPR2 High Rate Mode feature. When the HIPR2 High Rate Mode feature is enabled and turned on, the maximum total provisioned system TPS is increased to 1M. After the HIPR2 High Rate Mode feature has been enabled and turned on, continue the procedure with 11.
If the maximum total provisioned system TPS is 1M, or the maximum total provisioned system TPS is 500,000 and will not be increased, and adding the IPSG M2PA linkset will exceed the maximum total provisioned system TPS, the IPSG M2PA linkset cannot be added unless the amount of available TPS is reduced enough to allow the IPSG M2PA linkset to be changed. The available TPS can be increased by performing one or more of these actions.
- The IP TPS values of some IPGWx linksets have to be changed. To perform this action, continue the procedure with 8.
- The MAXSLKTPS values of some IPSG linksets (and the RSVDSLKTPS values if necessary) have to be changed. To perform this action, continue the procedure with 8.
- Some ATM high-speed signaling links have to be removed. To perform this action, continue the procedure with 6.

Perform these actions as necessary.

Perform the Configuring an IPGWx Linkset procedure to change the IPTPS value for any linksets shown in the rtrv-ls output whose IPGWAPC value is yes.
Perform one of these actions to change the MAXSLKTPS value (and RSVDSLKTPS value if necessary) for any linksets shown in the rtrv-ls output whose IPSG value is yes.
- If the ADAPTER value of the linkset is M3UA, perform the Changing an IPSG M3UA Linkset procedure.
- If the ADAPTER value of the linkset is M2PA, continue the procedure with 10.

Perform one or both of these actions to increase the available TPS if needed.

An IPLIMx card that contains signaling links has to be removed. To perform this action, continue the procedure with 7.
Some ATM high-speed signaling links have to be removed. To perform this action, continue the procedure with 6.

If you do not wish to perform other actions to increase the available TPS and the available TPS will allow the IPSG M2PA linkset to be changed, continue the procedure with 11.

Reduce the MAX SLKTPS, and RSVDSLKTPS value if necessary, for the linksets displayed in 9 by entering the chg-ls command with the new maxslktps and rsvdslktps values. For this example, enter these commands.
chg-ls:lsn=ipsglsn:maxslktps=3000

chg-ls:lsn=ipsglsn2:maxslktps=3000

Note:
Thersvdslktps value must be less than or equal to themaxslktps value.

When this command has successfully completed, this message should appear.

CHG-LS: MASP A - COMPLTD
```
Change the linkset by entering the chg-ls command with the name of the linkset and at least one of these optional parameters and values.
- rsvdslktps = 100 - MaxTPS
- maxslktps = 0 - MaxTPS
- tpsalmtype = rsvdslktps or maxslktps
- lsusealm = 10 - 100
- slkusealm = 10 - 100
For this example, enter this command.

chg-ls:lsn=lssg1101:rsvdslktps=500:maxslktps=3000:tpsalmtype=maxslktps :lsusealm=60:slkusealm=70

Note:
Thersvdslktps value must be less than or equal to themaxslktps value.

When this command has successfully completed, this message should appear.

Note:
There are other optional parameters that can be specified with thechg-ls command, but are not required for anIPSG M2PA linkset. These parameters and their usage are discussed in theOther Optional Parameters section of this procedure.

Verify the changes using the rtrv-ls command specifying the linkset name specified in 11. For this example, enter this command.

rtrv-ls:lsn=lssg1101

If the linkset that was changed in this procedure was an IPSG M2PA linkset when this procedure was started, this procedure is finished.

If the linkset that was changed in this procedure was either a non-IPSG linkset or an IPSG M3UA linkset when this procedure was started, preform the Adding an IPSG M2PA Signaling Link procedure to add IPSG M2PA signaling links to the linkset.
