Prerequisites and Limitations
The current release of ISC TEM involves certain prerequisites and limitations, which are described in this section.
See Cisco IP Solution Center Installation Guide, 4.1 for general system recommendations.
General Limitations
Concurrent use of the same installation is not supported. Let issued service requests finish deployment before issuing other service requests to avoid conflicts. This is described in more detail in the tunnel provisioning chapters.
The concurrency limitation also implies that opening multiple browsers displaying a single ISC installation is not recommended.
ISC TEM only supports MPLS-TE topology with point-to-point links.
Feature-Specific Prerequisites and Limitations
Some features might only be available with a particular license. In addition, the number of nodes provided by the license limits the size of the network. For more information, see Licensing Schemes.
A number of specific requirements are associated with the TE Discovery task. These are described in TE Discovery Prerequisites.
In the Planning portion of the current implementation of ISC TEM, concurrent use is not recommended as users working simultaneously risk being unable to commit their changes.
JRE version 1.4.2_04 or higher should be installed on the client computer, and if the user does not already have Java installed, they can use the links on the Topology Tool page to install the version that is bundled with ISC.
Non-POS interfaces cannot be protected on IOS-XR devices.
For users who have a repository that predates the ISC 4.1 release and has been upgraded to a 4.1 repository, you need to run a TE Discovery task to collect software version information from the devices before deploying service requests.
Non-Cisco Devices and ISC TEM
ISC TEM does not manage non-Cisco devices and ISC cannot be used to provision them.
ISC will, however, discover non-Cisco devices and store them in the repository. Tunnels can be run through these devices, the bandwidth consumed can be accounted for, but the devices are not otherwise managed by ISC. TE tunnels originating from non-Cisco devices will not be discovered.
Sorting can be performed on different attributes in various parts of the ISC TEM GUI. However, due to the added support for non-Cisco devices, sorting cannot be performed on Device Name and MPLS TE ID in the TE Nodes List window.
Supported Platforms
For supported devices and IOS platforms, see Cisco IP Solution Center Installation Guide, 4.1.
Preconfiguration Process Overview
The preconfiguration process sets up key parameters that enable the system to collect TE network information and subsequently deploy TE configurations on the chosen network.
An overview of the preconfiguration process is provided in Figure 2-1.
Figure 2-1 Preconfiguration Process
Before commencing the preconfiguration process, MPLS-TE needs to be enabled on the network devices by making sure that the IP addresses used as devices' TE IDs are accessible from the management station (this step is not supported by ISC TEM).
The preconfiguration process includes the following steps:
Step 1
Set up new user and install license keys—To run the TEM blade of ISC, it is necessary to create a new user and install license keys. These keys will enable the user to view and manage the TE tunnels and resources using ISC. (see ISC TEM Setup and Installation)
Step 2
Create a provider—The provider is a concept designed to allow many different operators to work on ISC TEM simultaneously, each working on different networks. Thus, each provider has to be defined and used as a reference operator for future work on the system. (To create a provider, see Cisco IP Solution Center Infrastructure Reference, 4.1.)
Step 3
Create a region for the provider—The region is important because a single provider could have multiple networks. The region is used as a further level of differentiation to allow for such circumstances. (To create a region, see Cisco IP Solution Center Infrastructure Reference, 4.1.)
Step 4
Create a seed device—This IOS Device will be the seed router for network discovery. The network discovery process uses the seed router as an initial communication point to discover the MPLS TE network topology. A set of TE enabled devices, links, explicit paths, tunnels, and static routes are then populated to the database. (To create a seed router, see Cisco IP Solution Center Infrastructure Reference, 4.1.)
Step 5
Create a TE Provider—Providers can be defined as TE provider, if they are supporting MPLS TE in their network. It is necessary to create a TE provider to enable a TE network to be managed. All TE related data associated with a given network is stored under a unique TE provider. A provider and region uniquely define a TE provider (see Creating a TE Provider).
Step 6
Run a Discovery Task—Discover the TE network for a particular TE provider to populate the repository with a view to creating primary and backup tunnels (see "TE Network Discovery").
Step 7
Set Up Management Interfaces—Set up management interfaces for discovered devices or update server host file with resolution for all discovered devices. This step is only necessary if the devices in the TE network are not accessible via their hostnames (see Setting Up Management Interfaces).
Note
If Telnet is selected to communicate with the seed router, Telnet must also be used for the other network devices. Likewise, if SSH is selected for the seed router, SSH must be used for all other devices.
ISC TEM Setup and Installation
Before setting up ISC TEM, the ISC software must be installed. To do so, see Cisco IP Solution Center Installation Guide, 4.1.
To set up a new ISC TEM user, one or more users with a TE role must be created. For step by step instructions, see Cisco IP Solution Center Infrastructure Reference, 4.1.
Installing an ISC TEM License
Cisco IP Solution Center Traffic Engineering Management (ISC TEM) offers the license structure described in "Introduction to ISC TEM."
For an explanation of license keys in ISC, see Cisco IP Solution Center Infrastructure Reference, 4.1.
To install a TE license, use the following steps:
Step 1
Log into ISC with the following default values:
•
User Name: admin
•
Password: cisco
Step 2
Navigate Administration > Security > Users.
Step 3
Click Create.
Step 4
Fill in User ID, Password, Verify Password, and the Personal Information section.
Step 5
Click Edit to edit the assigned roles.
Step 6
Select TERole and click OK. TERole provides full access to ISC TEM. The TEServiceOpRole only has the privilege to access the tunnel admission SR.
Step 7
Click Save.
Step 8
Navigate Administration > Control Center > Licensing.
Step 9
Enter the three TEM license keys for TE, TE/RG, and TE/BRG successively:
•
Click Install.
•
Enter a license key.
•
Click Save.
Repeat the procedure for each license key.
Typing in all three license keys is the only valid installation.
Step 10
Log out as admin.
Step 11
Log in as the user created above.
You are now ready to start using ISC TEM.
Note
The admin role should only be used to manage ISC and not to perform network management operations.
Editing DCPL Properties (Optional)
The ISC Dynamic Component Properties Library (DCPL) includes a wide variety of properties that are accessible from the GUI, some of which can be modified.
The various DCPL properties in ISC, including those pertaining to ISC TEM, and the process for editing these properties are described in Cisco IP Solution Center Infrastructure Reference, 4.1.
Warning
Do not attempt to modify the DCPL properties unless you fully understand the implications.
In the ISC GUI, the DCPL properties are found in Administration > Control Center > Hosts. Select a check box for a specific host and click the Config button.
The DCPL properties pertaining to ISC TEM are found in the following folders:
•
Provisioning > Service > TE
•
TE
•
TETopology
Creating a TE Provider
After a provider and a region for that provider have been set up (see Cisco IP Solution Center Infrastructure Reference, 4.1), create a TE provider using the following steps:
Step 1
Navigate Service Inventory > Inventory and Connection Manager > Traffic Engineering Management.
The Traffic Engineering Management Services window shown in Figure 2-2 appears.
