Configuring and Monitoring PNNI Addresses

This chapter describes how to configure and monitor private network node interface (PNNI) addresses, including address summaries, reachable addresses, and address scope mapping.

You can use the following sections to display, modify, add, and delete PNNI addresses:

• Using the Address Summary Window

• Using the Reachable Addresses Window

• Using the Scope Mapping Window

Using the Address Summary Window

Address summarization allows scalability across multiple networks by reducing the amount of addressing information that needs to be distributed. When you use a single reachable address prefix to represent a collection of end stations or node addresses, each node advertises its table of reachable addresses into its peer group.

The Address Summary window contains information that identifies a selected node and shows the address prefixes that are summarized by the node to an upper-level logical group node. You can use the Address Summary window to do the following tasks:

• Displaying Address Summaries

• Modifying an Address Summary

• Adding an Address Summary

• Deleting an Address Summary

Displaying Address Summaries

The Address Summary window opens (Figure 7-1).

The address summary information for the selected node is displayed in the list of address prefixes.

These fields are described in Table 7-1.

Step 4 Click Close after you have read the address summary information.

Figure 7-1: Address Summary Window

Modifying an Address Summary

Step 3 Select PNNI Options>Summary Addresses to display the Address Summary window (Figure 7-1).

Step 4 Select a summary address from the list to modify.

Step 5 Click Modify.

The Address Summary: Modify window opens (Figure 7-2).

Figure 7-2: Address Summary: Modify Window

For descriptions of these fields, see Table 7-1.

Step 7 Click OK to accept your changes and close the window.

Step 8 Click Apply in the Address Summary window to apply your changes to the agent and close the window.

Adding an Address Summary

Step 3 Select PNNI Options>Summary Addresses to display the Address Summary window (Figure 7-1).

Step 4 Click Add.

The Address Summary: Add window opens. This window is identical to the one used for modifying an address summary (Figure 7-2).

Step 5 Enter the address prefix for this summary address.

Step 6 Specify these attributes for this summary address:

• Type---Select Internal or External.

• Suppress---Select Yes or No to specify whether to suppress advertising.

For descriptions of these fields, see Table 7-1.

Step 7 Click OK to add the new summary address and close the window.

A new row appears in the summary address list.

Step 8 Click Apply in the Address Summary window to apply your changes to the agent and close the window.

Deleting an Address Summary

Step 3 Select PNNI Options>Summary Addresses to display the Address Summary window (Figure 7-1).

Step 4 Select a summary address in the table.

Step 5 Click Delete.

A confirmation message appears.

Step 6 Click OK to delete the summary address, or click Cancel to cancel the deletion.

Step 7 Click Apply in the Address Summary window to apply your changes to the agent and close the window.

Using the Reachable Addresses Window

Reachable address prefixes are the addresses that can be reached by any given node. Reachable addresses can be two types: summary addresses or foreign addresses. A foreign address is an address prefix associated with a node that does not match any of the summary addresses of the node. You can use reachable address information for monitoring or troubleshooting the connections from a node.

You can use the Reachable Addresses window to do the following tasks:

• Displaying Reachable Addresses

• Adding a Reachable Address

• Deleting a Reachable Address

Displaying Reachable Addresses

The Reachable Addresses window opens (Figure 7-3).

Figure 7-3: Reachable Addresses Window

The reachable address information for the selected node, filtered by the selected advertising node, is displayed in the reachable address table. These fields are described in Table 7-2.

Step 5 Click Close when you have read the reachable addresses.

Table 7-2: Reachable Addresses Field Descriptions

Field	Description
PNNI Node	Node name that is distributed to other nodes through PNNI flooding. The default node name is the host name of the switching system.
PNNI Level	Level of PNNI hierarchy at which this node exists. This value is used to determine the default node ID and the default peer group ID for this node.
ATM Address	ATM address of the node.
Advertising Node	Node that advertise reachability from the selected node address.
Address Prefix	ATM end system address prefix for this reachable address.
Interface	The local interface over which the reachable address can be reached.
Adv. Node	The node ID of a node advertising reachability to the address prefix.
Address Type	The type of reachability from the advertising node to the address prefix: internal or external.
Status Active	Indicates whether the reachable address prefix is operationally valid.
Status Advertised	Indicates whether the reachable address prefix is being advertised by this node.
Protocol	The routing mechanism used to learn the connectivity from the advertising node to the reachable address prefix. Note Only addresses with the "Management" protocol can be added or deleted.
VP Capable	Indicates whether virtual path connections (VPCs) can be established from the advertising node to the reachable address prefix.
E.164 Address	E.164 address used when a call is forwarded over this address and interface. The E.164 addresses are used for routing the calls over a public network using ISDN.

Adding a Reachable Address

Step 3 Select PNNI Options>ATM Routes to display the Reachable Addresses window (Figure 7-3).

Step 4 Click the button to the right of the Advertising Node field to display the popup list of nodes that advertise for the selected node (Node Name) and select an advertising node to use for the reachable address you are adding.

The reachable address information for the selected node, filtered by the selected advertising node, is displayed in the reachable address table. These fields are described in Table 7-2.

---

Note Only addresses with the Management protocol can be added.

---

Step 5 Click Add.

The Reachable Address: Add window opens (Figure 7-4). This window is identical to the one used to modify a reachable address.

Figure 7-4: Reachable Address Add Window

For descriptions of these fields, see Table 7-2.

Step 8 Click OK to accept the addition and close the window.

Step 9 Click Apply in the Reachable Addresses window to apply your changes to the agent and close the window.

Deleting a Reachable Address

Step 3 Select PNNI Options>ATM Routes to display the Reachable Addresses window (Figure 7-3).

Step 4 Click the button to the right of the Advertising Node field to display the popup list of nodes that advertise for the selected node (Node Name) and select an advertising node.

The reachable address information for the selected node, filtered by the selected advertising node, is displayed in the reachable address table. These fields are described in Table 7-2.

---

Note Only addresses with the Management protocol can be deleted.

---

Step 5 Select a reachable address from the table to delete.

Step 6 Click Delete....

A confirmation message appears.

Step 7 Click OK to delete the reachable address, or click Cancel to cancel the deletion.

Step 8 Click Apply in the Reachable Addresses window to apply your changes to the agent and close the window.

Using the Scope Mapping Window

Both individual and group addresses have membership scopes, which are used to determine the scope of advertisement of reachable addresses. By configuring address scope, you can keep advertised reachability information within configurable bounds. This feature allows flexibility in control of reachability information, in cases such as network restructuring or security control.

You can use the Scope Mapping window to do the following tasks:

• Displaying Address Scope Mapping

• Modifying Address Scope Mapping

Displaying Address Scope Mapping

The Scope Mapping window opens (Figure 7-5).

The information in this window is described in Table 7-3.

Step 4 Click Close after you read the scope mappings.

Figure 7-5: Scope Mapping Window

Modifying Address Scope Mapping

The Scope Mapping window is displayed (Figure 7-5).

Step 4 Select Manual from the Scope Mode field.

Step 5 Select a PNNI level to modify (click in its cell) and enter the new routing level.

Repeat Step 5 for each scope mapping you want to modify.

---

Note PNNI levels for UNI scopes must be in sequence. For example, the PNNI level of UNI scope 4-5 cannot be less than the PNNI level of UNI scope 6-7.

---

Step 6 Click Apply to apply your changes and close the window.
