Administering a Survivable Backup CMS

Last Updated : Nov 20, 2024 |
Use the Survivable Processor form to associate a survivable backup CMS for either:

  • a C-LAN port on a specific ESS server,

  • a processor ethernet port on a specific ESS or LSP server

The Survivable Processor form is administered on the main server. The translations are sent to the ESS server or LSP during a file sync. After the file sync, the information on Page 2 is used by the LSP or the ESS server to connect to the CMS.

On Page 1 of the form, everything but the Network Region is pre-populated based on what was already administered on the Node Name form and the System Parameters ESS form.

Node Name: ESS1
IP Address: 192.0.9.0
ID: 30
Type: LSP

Option

Description

Network Region

Enter the network region in which the LSP or ESS server resides.

Use Page 2 of the Survivable Processor form to administer the CMS that is connected to a C-LAN or processor ethernet interface.

Field

Option

Description

Proc Chan

Displays the processor channel for this link.

Enable
Enter one of the following values in this field:

  • Enter n if this processor channel is disabled on the LSP or the ESS server.

  • Enter i (inherit) if this link is to be inherited by the LSP or ESS server. You can use the inherit option in the following cases:

    • The main server connects to the adjuncts using a C-LAN and you want the ESS server to use the same connectivity.

    • The main server connects to the adjuncts using the main server’s PE interface and you want the LSP or ESS server to connect to the adjunct using its PE interface.

  • Enter an o to override the processor channel information sent in the file sync from the main server. The override option causes the near-end address of the link to change to a p when the translations are sent from the main server to the LSP or the ESS server. Generally, you would want the override option when an adjunct connects to the main server using a C-LAN and you want the adjunct to connect to the LSP or the ESS server’s processor ethernet interface. When you enter an o in the enable field, you can enter the processor channel information for the LSP or the ESS server in the remaining fields.

Appl

Displays mis.

Mode

Enter s for server.

Interface Link

Enter p when the physical link is the processor ethernet interface on an LSP or ESS. Enter the C-LAN link number when the physical link is a C-LAN on an ESS.

Interface Chan

Enter the TCP channel number (5000-64500). The default for CMS is 5001 and is defined during CMS setup.

Destination Node

Enter the node name of the CMS server as assigned on the Node Names form. In these examples, cmshost is used.

Destination Port

Use the default of 0.

Session Local/Session Remote

The local and remote port assignments must be symmetrical between the Communication Manager system and the CMS. For example, if you use processor channel 10, set the local and remote port to 10.
