ces aal1 clock

To configure the AAL1 timing recovery clock for T1/E1 interfaces, use the ces aal1 clock interface configuration command.

ces aal1 clock {adaptive | srts | synchronous}

Syntax Description

Default

Synchronous

Command Mode

Interface configuration

Usage Guidelines

The clock mode must be synchronous for structured mode. In unstructured mode, use adaptive when a network-derived clock is not available.

Use srts when a network-derived clock is available but devices attached to the CES port use a different clock reference. The srts keyword samples the incoming clock, subtracts from the network clock, and sends the remainder in an AAL1 header. The clock is reconstructed during output by adding the residual to the network reference.

Use synchronous for all other modes.

Example

The following command shows setting the AAL1 timing recovery clock to adaptive mode.

ces aal1 service

To configure the type of ces service, use the ces aal1 service interface configuration command.

ces aal1 service {structured | unstructured}

Syntax Description

Default

Unstructured

Command Mode

Interface configuration

Usage Guidelines

The structured keyword means that each timeslot is an independent entity grouped into circuits, where each circuit has an independent PVC.

The unstructured keyword reduces the incoming serial data on the receiving end of the ATM network. The keyword also sets the service to single circuit, single PVC, where all timeslots are carried.

Example

The following example shows changing the mode for the ces aal1 service command to structured.

ces circuit

To configure the CES connection attributes, use the ces circuit interface command. To revert to the default setting, use the no form of this command.

ces circuit (0..31) [cas | cdv | circuit-name | partial-fill | shutdown | timeslots]
no ces circuit [cas | cdv | circuit-name | partial-fill | shutdown | timeslots]

Syntax Description

Default

See the syntax descriptions.

Command Mode

Interface configuration

Usage Guidelines

Channel-associated signalling provides information about the time slot (on or off the hook) and is updated once per multiframe.

Example

The following example shows setting the structured service CDV range to 5000 milliseconds.

ces dsx1 clock source

To configure a transmit clock source to the T1/E1 CES port adapter, use the ces dsx1 clock source interface configuration command.

ces dsx1 clock source {loop-timed | network-derived}

Syntax Description

(For T1) ces dsx1 framing {sf | esf}

To restore the default setting, use the no form of these commands.

Syntax Description

Default

The default for E1 is el_lt. The default for T1 is esf.

Command Mode

Interface configuration

Usage Guidelines

Use this command in configurations where the switch communicates with either the T1 or the E1 data line to configure the frame type for your circuit.

Example

The following example shows setting the E1 data line frame type to e1_mfCAS_lt.

Related Command

Example

The following example shows setting the cable length to 440 feet using the ces dsx1 lbo interface configuration command.

ces dsx1 linecode

To select the linecode type for the T1 or E1 line, use the ces dsx1 linecode interface configuration command.

(For E1) ces dsx1 linecode {ami | hdb3}
(For T1) ces dsx1 linecode {ami | b8zs}

Syntax Description

Default

The default for T1 is b8zs. The default for E1 is hdb3.

Command Mode

Interface configuration

Usage Guidelines

The T1 service provider determines which linecode type, either ami or b8zs, is required for your circuit. The E1 service provider determines which linecode type, either ami or hdb3, is required for your circuit.

Example

The following example specifies b8zs as the linecode type for the T1 interface.

ces dsx1 loopback

To configure loopback for the T1 or E1 circuit emulation port adapter module, use the ces dsx1 loopback interface configuration command.

ces dsx1 loopback {line | noloop | payload}

Syntax Description

Default

noloop

Command Mode

Interface configuration

Usage Guidelines

This command is useful when testing the circuit emulation port adapter module.

Example

The following example shows setting the loopback to payload.

ces dsx1 signalmode robbedbit

To configure the signalmode to robbedbit, use the ces dsx1 signalmode robbedbit interface configuration command. To revert to the default setting, use the no form of this command.

ces dsx1 signalmode robbedbit
no ces dsx1 signalmode robbedbit

Syntax Description

This command has no keywords or arguments.

Default

no

Command Mode

Interface configuration

Usage Guidelines

A T1 frame consists of 24 time slots (DS0) that send at a rate of 64 kbps. T1 defines the ability to send signalling in-band on individual time slots by removing the low bit of each byte for signalling in robbedbit mode. This procedure allows 8 kbps for signalling and leaves 56 kbps for data.

In structured mode, you can send the T1 signalling information across the B-ISDN network. This means that after you set the port in robbedbit signalling mode, and enable CAS on individual circuits that need this type of service, you are robbing bits from the DS0. The system then puts the bits in the specified format to be sent across the B-ISDN network and reinserts them at the passive side on the CES-IWF connection.

ces pvc

To configure the destination port for the circuit, use the ces pvc interface configuration command.

ces pvc (0..31) {interface atm card/subcard/port | dest-address atm-address {vpi vpi-number | vci vci-number}}[retry-interval [first retry-interval] [maximum retry-interval]]

Syntax Description

Command Mode

Interface configuration

Usage Guidelines

Use the interface option to create a hard PVC. Use the dest-address option to create a soft PVC.

You must configure both sides of the CES circuits because the source (the active side in CES-IWF) time slots are not recognized at the destination (the passive side).

Each CES circuit has an ATM address. When configuring the source PVC, you need the destination ATM address. See the show ces address command.

Examples

The following example shows setting a hard PVC on interface ATM 1/0/0.

The following example shows setting an unstructured CES soft PVC.

The following example shows setting a structured hard PVC.

clear lane le-arp

To clear the dynamic LE_ARP table or a single LE_ARP entry of the LANE client configured on the specified subinterface or emulated LAN, use the clear lane le-arp privileged EXEC command.

clear lane le-arp [interface atm card/subcard/port [.subinterface-num] | name elan-name]
[mac-address mac-addr | route-desc segment seg-num bridge bridge-num]

Syntax Description

Command Mode

Privileged EXEC

Usage Guidelines

This command only removes dynamic LE_ARP table entries. It does not remove static LE_ARP table entries.

If you do not specify an interface or an emulated LAN, this command clears all the LANE ARP tables of any LANE client in the switch.

If you specify a major interface (not a subinterface), this command clears all the LANE ARP tables of every LANE client on all the subinterfaces of that interface.

Use of this command also removes the fast-cache entries built from the LANE ARP entries.

Examples

The following example clears all the LANE ARP tables for all clients on the switch.

The following example clears all the LANE ARP tables for all LANE clients on all the subinterfaces of interface atm 0.

The following example clears the entry corresponding to MAC address 0800.AA00.0101 from the LE_ARP table for the LANE client on the emulated LAN red.

The following example clears all dynamic entries from the LE_ARP table for the LANE client on the emulated LAN red.

The following example clears the dynamic entry from the LE_ARP table for the LANE client with next-hop router descriptor segment number 1, bridge number 1, on the emulated LAN red.

clear lane server

To force a LANE server on a specified subinterface or emulated LAN to drops the Control Direct and Control Distribute VCCs to a given LANE client and force the client to rejoin, subject to the new bindings, use the clear lane server privileged EXEC command.

clear lane server {interface card/subcard/port[.subinterface-num] | name elan-name}
[client-atm-address client-atm-addr | lecid lecid | mac-address mac-addr |
route-desc segment seg-num bridge bridge-num]

Syntax Description

Command Mode

Privileged EXEC

Usage Guidelines

After changing the bindings on the configuration server, enter this command on the LANE server. The LANE server drops the Control Direct and Control Distribute VCCs to the LANE client. The client then asks the LANE configuration server for the location of the LANE server of the emulated LAN it is requesting to join.

If no LANE client is specified, all LANE clients attached to the LANE server are dropped.

Example

The following example forces all the LANE clients on the emulated LAN named red to be dropped. When they try to join again, they are forced to join a different emulated LAN.

client-atm-address name

To add a LANE client address entry to the configuration servers configuration database, use the client-atm-address name lane configuration server database command. To remove a client address entry from the table, use the no form of this command.

client-atm-address atm-address-template name elan-name
no client-atm-address atm-address-template

Syntax Description

Default

No address and no emulated LAN name are provided.

Command Mode

Lane configuration server database

Usage Guidelines

The effect of this command is to bind any client whose address matches the specified template into the specified emulated LAN. When a client comes up, it consults the LANE configuration server, which responds with the ATM address of the LANE server for the emulated LAN. The client then initiates join procedures with the LANE server.

Before this command is used, the emulated LAN specified by the elan-name argument must be created in the configuration server's database by using the name server-atm-address command.

If an existing entry in the configuration server's database binds the LANE client ATM address to a different emulated LAN, the new command is rejected.

This command affects only the bindings in the named configuration server database. It has no effect on the LANE components themselves.

The client-atm-address name command is a subcommand of the glo
