IES Service An Internet Enhanced Service (IES) is a routed connectivity service where the subscriber communicates with an IP (Layer 3) router interface to send and receive Internet traffic. The 7750 SR buffers service traffic and shapes it to conform to SLA parameters. Buffer a llocation is programmable per-service to accommodate different maximum burst sizes (MBS). Each service can use multiple queues to enable shaping, policing and marking of different flows. The 7750 SR can also shape and police on service egress so customers can purchase sub-rate services (e.g. Intern et services) with asymmetric SLAs.

Characteristics  

   

Service Access Point (SAP) acts as the access point to the subscriber’s network SAP supports multiple encapsulation types, such as: Ethernet null, dot1q, q-in-q, SONET/SDHIPCP, BCP-null, BCP-dot1q and ATM. Supports VRRP, Cflowd, secondary IP addresses, and ICMP options on customer IP interfaces Interface supports RIP, OSPF, IS-IS, and BGP. QoS and filter policies Does not require a Service Distribution Path (SDP); traffic is routed rather than being encapsulated in a tunnel

Services must be associated with a customer. Though a service may only have one customer, that customer may have more than one associated to them. To create a Customer using the 5620 SAM, the network administrator or operator will use t he following sequence: Customers  From the Main Menu, select Manage  In the new window, click on the Create button  Complete the customer’s details as provided in the configuration window  Click on the OK button. 

To verify that the customer was created, or edit any detail: Customers from the Main Menu  Select Manage  Click on the Search button  Double-click on the appropriate entry or, select the appropriate customer and click on the Edit button.  Review or modify the details, as required.  Click OK or Apply to save the changes or Cancel to disregard any modifications and close the window. 


Configure Access Port

8·4·7



As discussed, a service requires a port facing the customer edge to be configured for Access and an Encapsulation type specified. To configure a port:  Navigate to the Equipment view in the Navigation Tree  Expand the tree and select the appropriate port or ports. It is possible to configure multiple ports at the same time by through the Shift – Click or Ctrl – Click method.  Right-click and select Properties from the contextual menu  From the Mode drop-down menu, select Access  From the Encapsulation Type drop-down menu, select the appropriate encapsulation type  Set the port MTU. Remember that the port MTU must be set to a value set to support the largest service MTU to be supported on that port.  Select OK to complete the configuration.

Having clicked the Apply button, the configuration window remains open and the changes are saved in the 5620 SAM database. However, service components (Service Sites, Access Interfaces and SDP Bindings) have yet to be configured for the service to be commissioned. To configure service sites:  Navigate to the Components window of the service configuration form  Select IES and right-click  Select Create Site and select the sites to participate in the VPLS service from the list. This may be done individually or by selecting multiple entries at once.  Click the OK button on the bottom of the Components window (i.e., the containing window in this case)  Confirm the sites have been added in the Components window It is important to remember that, even though they appear in the configuration window, the changes will not be sent to the managed devices and saved to the 5620 SAM database until the OK or Apply button at the bottom of the window (referred to as the Containing Window) is clicked.


Create L3 Interface

8 · 4 · 10



Service Access Points are virtual interfaces to provide customer access to the service provider’s network. An SAP consists of: a physical port configured to support Access points; an encapsulation type; and, an encapsulation ID value unique to the port. To create a SAP: 

Navigate to the Component window for the service.



Navigate to the Access Interface of the appropriate Site.



Right-click and select Create L3 Access Interface.



Assign an interface name (mandatory) and complete the remaining parameters, as required.



Click the Port tab and then click the Select button.



Click the Search button. All Access ports on the managed device will appear in the list. Select the appropriate port and click the OK button.


Create L3 Access Interface (SAP) [Cont.]

Encapsulation Value, as required

8 · 4 · 11



The SAP also requires an encapsulation ID value that is unique to the port upon which it is being created. To assign an encapsulation ID:  Select the Port tab.  Assign the Outer Encapsulation Value and Inner Encapsulation Value , as required. The use of encapsulation values will be determined by the encapsulation type configured on the port being used. This was set during the process to create an Access port, discussed earlier in the course.  Select the Address tab.


Create L3 Access Interface (SAP) [Cont.]

8 · 4 · 12



An IES is a Layer 3 service and will therefore require an IP Address on the SAP. To assign an IP address to the SAP: Open the Address tab in the service configuration window  Click on the Add button  Enter the appropriate IP address according to scheme provided. The Address ID determines whether the IP address is either the primary (ID # 1) or a secondary address (ID# 2 – 16).  Configure the parameters under the remaining windows, as required. These are optional settings and may be added at any time in the future without service interruption. These parameters include: 





QoS: assign access ingress and egress policies



Schedulers: assign ingress and egress schedulers for HQoS



ACL: assign ingress and egress filter policies



Accounting: define an accounting policy



ICMP: define type and rate that ICMP messages will be processed on this interface



ARP: define static entries in the ARP table. Turn on Proxy ARP and define proxy ARP policies



DHCP: configure DHCP relay, Option 82 and the DHCP lease state table.



Anti-Spoofing: turn on auto creation of anti-spoofing filters and configure static hosts

Click on OK or Apply to complete the configuration

Opening the Components tab will provide a tabular view of the service configuration. Expand the Access Interface entry to confirm that the SAP has been created and verify that its status indicates that the interface is Up.


Add SAP to Internal Gateway Protocol (IGP )

OK

8 · 4 · 13



Though the IES has been created, traffic will not be forwarded through the interface until it participates in the Internal Gateway Protocol’s routing table. To do so, the interface must be assigned to an Internal Gateway Protocol (IGP) including an appropriate area or autonomous system, as required by the protocol. To configure the IES interface to participate in the IGP route table: Open the Components tab of the IES Navigate to the IES Access Interface and select the appropriate SAP. Right-click and select Properties from the contextual menu In the window that appears (L3 Access Interface), select the Protocols tab Select the Add button. The Create Interface window appears. From the drop-down menu, select the appropriate protocol to which the interface will be added and click OK . Repeat this process for each of the IGP in which this interface is to participate. The protocol(s) will appear in the list. Select OK to complete the configuration and deploy the changes to the 5620 SAM database and network element(s). The IES will now be able to pass traffic through the SAP. In the new window (L3 Access Interface), click on the Select button in the Routing Instance portion of the configuration window List the available routing instances by clicking on the Search button. Using Search filters can refine the list. Select the appropriate routing instance from the list and click OK


Protocol Properties

8 · 4 · 14



As part of the service provider’s policy in providing the IES, it may be necessary to modify the default actions of the IGP on this interface. For example, the IES interface may be used to provide routing to another carrier’s network, in which case, it may be desirable to prevent the exchange of routing tables by configuring the interface for Passive mode. To modify the IGP properties for an IES interface:  Navigate to and select the IES SAP in the Components tab of the service. Properties from the contextual menu.  Select the  Select the Protocols tab, select the protocol instance and then select the Properties button, which will open the OSPF Interface window.  Click on the Protocol Properties tab.  Configure the parameters, as require and then click on OK at the bottom of the list to save the changes.


Manage IES

8 · 4 · 15



Once created, the network administrator or operator is able to view and/ or manage the IES from the 5620 SAM GUI. To manage or view the IES service configuration:  Select Manage  Services from the Main Menu  Set the Search filter parameters, as required  Click on the Search button  Select the service from the list, and double click on the service. The configuration window appears on the screen. Service configuration information is provided under the appropriate tabs listed at the top of the window. Parameters in drop-down menus or in the white blocks may be changed. Changes to an existing service will prompt a warning to which the network administrator or operator will be required to acknowledge before changes will be affected. Viewing a graphical representation of the service is possible by clicking on the Topology View button of either window. An example is provided on the next page.


View Service Topology

Service Access Point Port ID:Outer Encap: Inner Encap

Service Type Service ID: Site ID 8 · 4 · 16



The Service Topology View displays the service components configuration and status information at a glance. Information available includes: 

Service Type – indicated within the Site icon (VPLS, in this case). The Service ID and Site ID

are posted below the icon.  Service Access Point – the square with two arrows contained within the icon. The Port ID and Outer and Inner Encapsulation ID are posted below the icon. Select any component in the Topology View. Right-clicking provides a contextual menu for the selected item. Color coding is used to indicate Fault conditions based upon the ITU-T X.733 standard (discussed later in the course). In the picture above, green indicates that the service components are reporting a normal operational status. The check mark indicates that the managed device is in active communication with the 5620 SAM.
