Refer to Appendix D of this command reference for a detailed list of commands that have been removed, changed or replaced.

scheduler allocate

To guarantee CPU time for processes, use the scheduler allocate global configuration command.
To restore the default guaranteed CPU time, use the no form of this command.

: scheduler allocate interrupt-time process-time
: no scheduler-allocate

Syntax Description

interrupt-time

Integer (in microseconds) that limits the maximum number of microseconds to spend on fast switching within any one network interrupt context. The range is 500 to 6000 microseconds. The default is 4000 microseconds.

process-time

Integer (in microseconds) that guarantees the minimum number of microseconds to spend at the process level when network interrupts are disabled. The range is 500 to 60000 microseconds. The default is 200 microseconds.

Defaults

Approximately five percent of the CPU is available for process tasks.

Release Modification

11.2(8.0.1)

New command

Usage Guidelines

The normal operation of the network server allows the switching operations to use as much of the central processor as required. If the network is running unusually heavy loads that do not allow the processor the time to handle the routing protocols, give priority to the system process scheduler.
Use the scheduler allocate command to guarantee processor time.

Examples

The following example makes 20 percent of the CPU available for process tasks.

Switch(config)# scheduler allocate 2000 500

scope

To filter ATM signalling call failures that occur within the switch and on other switches, use the scope ATM signalling diagnostics configuration command. To disable this feature, use the no form of this command.

scope map

To specify the mapping from a range of organizational scope values (used at UNI interfaces) to a PNNI scope value (such as in terms of PNNI routing-level indicators), use the scope map PNNI node-level subcommand. To set to default a range of organizational scope values, use the no form of this command.

: scope map low-org-scope [high-org-scope] level level-indicator
: no scope map low-org-scope [high-org-scope]

Syntax Description

low-org-scope

Specifies the low end of the range of organizational scope values. The valid range of organizational scope values is from local (1) to global (15).

high-org-scope

Specifies the high end of the range of organizational scope values. The valid range of organizational scope values is from local (1) to global (15). If no value is specified, then the range includes only one entry (for example, high-org-scope equals low-org-scope).

level-indicator

Specifies the PNNI scope value to which the range of organizational scope values is mapped. The range is from 0 to 104.

Defaults

Table Table 17-1 shows the default values specified in the ATM Forum PNNI 1.0 Specifications.

Command History

Release Modification

11.2(5)

New command

Usage Guidelines

The scope map command is used to change the values of specific entries. This command is only accepted when the scope mode is set to manual.

When the organizational scope of a registered address maps to a PNNI level that is lower in the PNNI hierarchy (larger PNNI routing level) than the level of this node, the registered address is not advertised. Similarly, when the connection scope of a setup attempt maps to a PNNI level that is lower in the PNNI hierarchy than the level of this node, then only destinations directly attached to this switch router are considered acceptable.

Note Modifying the node level without altering the scope map table can result in some advertisements being suppressed.

The ATM switch router provides an option to automatically adjust the level changes. In automatic mode, the default scope map table is tied to the level of the node when it is generated.

Note that the default organizational scope of an individual address is global (15), and the default organizational scope of a group address is local (1).

Examples

The following example shows setting the scope mode to manual and setting the scope map entries for organizational scope values 1 through 5 to PNNI level 96, using the scope map PNNI node-level subcommand.

Switch# configure terminal

Switch(config)# atm router pnni

Switch(config-atm-router)# node 1

Switch(config-pnni-node)# scope mode manual

Switch(config-pnni-node)# scope map 1 5 level 96

Command Description

scope mode

Specifies the configuration mode of the mapping from organizational scope values (used at UNI interfaces) to PNNI scope (such as PNNI routing-level indicators).

show atm pnni scope

Displays the mapping from organizational scope values—used at UNI interfaces—to PNNI scope (such as PNNI routing level indicators).

scope mode

To specify the configuration mode of the mapping from organizational scope values (used at UNI interfaces) to PNNI scope (such as PNNI routing-level indicators), use the scope mode node-level subcommand.

: scope mode {automatic | manual}

Syntax Description

automatic

Generates a default scope mapping table automatically which is tied to the PNNI level of the node. In this mode, no modifications of the scope mapping table entries are allowed.

manual

Allows for manual configuration of the scope mapping table using the scope map command.

Defaults

The default scope mappings for automatic are shown in Table 17-2.

Table 17-2 Default Scope Mappings for Automatic Mode

Organizational Scope Range	ATM Forum Default Level	Automatic Mode Level

11.2(5)

New command

Usage Guidelines

Use this command to modify the way in which the default scope mapping table is computed.

Using the automatic mode ensures that all organizational scope values cover an area at least as wide as this node's peer group, even when the node is at a level higher than 96. As a result, all addresses including those of local scope are advertised across this node's peer group.

For each organizational scope value, the corresponding PNNI level is the minimum of the ATM Forum PNNI 1.0 default value and level l of this node.

Note that the scope mapping table is overwritten whenever the scope mode is changed from manual to automatic (for example, all scope map commands for this node are removed).

Examples

The following example shows setting the scope mode to manual using the scope mode PNNI node-level subcommand.

Switch# configure terminal

Switch(config)# atm router pnni

Switch(config-atm-router)# node 1

segment-target

To specify a target entry in a partially specified PNNI explicit-path, use the segment-target PNNI explicit-path configuration command.

: segment-target {name-string | node-id | node-id-prefix} [port hex-port-id | agg-token hex-agg-token-id]

Syntax Description

name-string

Name of the PNNI node.

node-id

Full 22-byte node ID for a PNNI node.

node-id-prefix

The first 15 or more bytes of a node ID for a PNNI node.

port hex-port-id

Optionally specifies an exit port to exclude for a PNNI node. Should be specified as a hexadecimal port ID rather than as a port name.

The default is to allow any valid exit port.

agg-token hex-agg-token-id

Optionally specifies the exit aggregation token, which is used in place of the port ID for higher-level PNNI LGNs.

The default allows any valid exit port.

Defaults

See "Syntax Description."

Command History

Release Modification

12.0(3c)W5(9)

New command

Usage Guidelines

Note See the atm pnni explicit-path command for a description of how to edit or delete an existing segment-target path entry.

Node IDs can be entered with either the full 22-byte length address, or as a node ID prefix with a length of 15 bytes or more. To specify routes that include higher-level nodes (parent LGNs) for other peer groups, we recommend that you enter exactly 15 bytes so that the address remains valid in the event of a PGL update.

Node IDs appear in the following format:

dec: dec: 13-20 hex digits

Note To display the node IDs that correspond to named nodes in a network, use either the show atm pnni identifier command or the show atm pnni topology command with the node keyword.

Node names can be entered instead of node IDs. If names are used to identify higher-level LGNs, the resulting explicit paths are not guaranteed to remain valid if the PGL changes in the neighboring peer group. To prevent invalid paths, configure all parent LGNs (for all potential PGL nodes) with the same node name.

An exit port can be specified for any entry. The port should be specified as a hexadecimal port ID rather than as a port name. For excluded entries, only this port is excluded from the path.

Note To display the corresponding hexadecimal port IDs for a node, use either the show atm pnni identifier command with the port keyword, or the show atm pnni topology command with the node and hex-port-id keywords.

Since the port-id could change if the following neighbor peer group changes PGL leaders, the aggregation token is used in place of the port ID for nodes with higher-level LGNs. The LGN aggregation token can only identify the port uniquely if the following entry is the next-node entry. Aggregation tokens are not allowed for excluded tokens.

Examples

The following example shows how to perform the following PNNI explicit-path configuration tasks:

Enter PNNI explicit-path configuration mode
Add one next-node
Add two segment-target nodes (these must appear in their desired routing order.)
Specify an LGN node by its 15-byte node ID prefix
Exit PNNI explicit-path configuration mode

12.0(3c)W5(9)

New command

Usage Guidelines

When enabled, SGCP listens on all interfaces for UDP packets that contain SGCP requests or responses. For call setup, SGCP allocates connections to endpoints: CES ATM single time slot circuits. For call teardown, SGCP releases connections between endpoints. The no form of the command releases all network connections established for SGCP and all endpoints from connections. It also returns resources allocated to SGCP. The no form also stops SGCP from listening for UDP packets. No attempt is made to gracefully release resources.

When SGCP receives a CreateConnection packet for the ATM switch router endpoint, the endpoint name is in the following format:

CBR.x.y.z/c

where x, y, and z are standard ATM switch router interface specifiers (card/subcard/interface), and c is a CES circuit ID.

For a CreateConnection packet to succeed:

There must be a CES card in slot x, subcard y, 0<=z<=3:

T1: 1<=c<=24

E1: 1<=c<=31

There must be a CES circuit defined with circuit ID c, with only a single time slot
(time slot = c) allocated to it.
There must be no PVC configured for the CES circuit.
The CES circuit must not be the destination end of a CES soft PVC.
The parent CES interface line state (shown by the show ces interface command) must be normal.
The SGCP global operational state (shown by the show sgcp command) must be active.

Note For SGCP to operate properly, even with the sgcp command in effect, you must not enter the sgcp graceful-shutdown command.

Examples

The following example enables SGCP.

Switch# configure terminal

Switch(config)# sgcp

Usage Guidelines

Use this command to determine the IP address and UDP port of the call agent for sending requests and responses if the call-agent address is not configured.

The gateway sends responses to the source IP address and port specified in the UDP packet containing the SGCP request.
The gateway sends a DeleteConnection request to the source IP address and port specified in
the UDP packet of the CreateConnection request that allocated the current connection.

If the address is specified, but no port is specified, SGCP uses the well-known SGCP port 2427.

Release Modification

12.0(3c)W5(9)

New command

Usage Guidelines

The graceful shutdown configuration is used while SGCP is active. This command stops SGCP operation after attempting to notify the call agent about the release of any connections in progress.

The no sgcp command operates in a similar manner in that any active network connections established by SGCP are torn down.

The gateway also sends DeleteConnection requests to the call agent for all endpoints allocated to connections. After responses (or retransmission limits, or call agent-initiated DeleteConnection) have been received for all connections, the gateway stops listening to UDP. During this activity, SGCP rejects any requests for new connections.

After you enter the sgcp graceful-shutdown command with SGCP enabled, the operational state of SGCP that theshow sgcp command reflects can be Down or Going Down. The Going Down state is entered only if there are active connections. Once all connections are inactive (not allocated and network connection released), the global operational state is Down. While sgcp is outstanding, the no form of this command resumes SGCP operation.

The no form of this command has no effect when issued while SGCP is not operating.

summary-address

To configure summary address prefixes on a PNNI node, use the summary-address node-level subcommand. To remove configured summary address prefixes, use the no form of this command.

: summary-address address-prefix [internal | exterior] [suppress]
: no summary-address address-prefix [internal | exterior]

Syntax Description

address-prefix

Specifies the summary address prefix. The maximum length of the address prefix is 19 bytes. Each character in the prefix is 4 bits. The length of the prefix must fall on a nibble boundary. In other words, the length of the prefix must be a multiple of 4 bits.

internal

Specifies local knowledge of reachability, including end-system addresses registered via ILMI address registration.

exterior

Specifies knowledge of reachability through remote networks or derived from other protocol exchanges outside the PNNI routing domain.

suppress

Indicates that neither the summary address nor any addresses for which the summary address is the longest matching prefix are advertised.

Defaults

Default summary addresses are controlled by the auto-summary command.

The default summary address type is internal.

Command Modes

PNNI node configuration

Command History

Release Modification

11.1(4)

New command

Usage Guidelines

Summary addresses can be used to decrease the amount of information advertised by this PNNI node. Summary addresses should only be configured when all end-system addresses matching the summary address are reachable from this switch (for example, not reachable through PNNI interfaces to other switches).

Summary addresses of type internal only summarize internal addresses reachable from this switch (such as ILMI-registered addresses and internal static routes). Summary addresses of type exterior only summarize exterior addresses reachable from this switch (for example, exterior static routes on IISP or public UNI interfaces).

Suppressed summary addresses can be used to prevent other PNNI nodes from learning of switch connectivity to certain addresses (for example, for back doors).

For more information, refer to the ATM Switch Router Software Configuration Guide.

Examples

The following script shows how to access the summary-address node-level subcommand.

Switch# configure terminal

Switch(config)# atm router pnni

Switch(config-atm-router)# node 1

Switch(config-pnni-node)# summary-address 48.91...

Defaults

Enabled.

Command Modes

Redundancy configuration

Command History

Release Modification

12.1(6)

New command

Usage Guidelines

Dynamic data refers to any states or data structures such as transit SVCs and transit or endpoint soft VCs. The sync dynamic-info command will work only if the sync config running command is enabled. Disabling the sync config running command will automatically disable dynamic-info (if so already enabled) because dynamic-info is not functional without RCSF enabled. You can turn off dynamic-info anytime regardless of the RCSF status.

Examples

Switch# configure terminal
Switch(config)# redundancy
Switch(config-r)# main_cpu
Switch(config-r-mc)# sync dynamic-info
