Configuring ATM Cell-Relay Promiscuous Mode

 

For ATM1 and ATM2 IQ with atm-ccc-cell-relay encapsulation, you can map all incoming cells from either an interface port or a virtual path (VP) to a single LSP without restricting the VCI number. Promiscuous mode allows you to map traffic from all 65,535 VCIs to a single LSP, or from all 256 VPIs to a single LSP.

To map incoming traffic from a port or VC to an LSP, include the promiscuous-mode statement at the [edit interfaces interface-name atm-options] hierarchy level:

You can include multiple vpi statements in the configuration.

To enable all VCIs in a VPI to open in ATM CCC cell-relay mode, you must also map the logical interface to a VPI by including the vpi statement in the logical interface configuration:

You can include this statement at the following hierarchy levels:

  • [edit interfaces interface-name unit logical-unit-number]

  • [edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]

Also, note the following:

  • For promiscuous mode, you must configure the port with atm-ccc-cell-relay encapsulation.

  • For ATM1 PICs and ATM2 IQ PICs, changing modes between promiscuous and nonpromiscuous causes all physical interfaces to be deleted and re-added.

  • For ATM1 PICs, and ATM2 IQ PICs, when you configure promiscuous mode, you cannot configure VCIs.

  • For ATM1 PICs, if you configure one port in port mode, all ports on the PIC operate in port mode. Likewise if you configure one logical interface in VPI mode, all logical interfaces on the PIC must operate in VPI mode.

  • For ATM2 IQ PICs, you can configure one or more logical interfaces in VPI promiscuous mode, and the other logical interfaces with any ATM encapsulation.

  • For ATM2 IQ PICs, when you configure promiscuous mode, you must also include the pic-type atm2 statement. For more information, see Configuring the ATM PIC Type.

  • For ATM2 IQ multiport PICs, you can configure one or more ports in port promiscuous mode, and the other ports with any ATM encapsulation.

  • For interfaces that are configured for cell-relay promiscuous virtual path identifier (VPI) mode, the show interfaces command output does not show OAM F4 cell statistics.

To configure ATM Cell-Relay Promiscuous Mode:

  1. Use the following statements to configure the port-promiscuous mode:

  2. Use the following statements to configure the VP-Promiscuous mode:

  3. To map incoming traffic from a port to an LSP, include the allow-any-vci statement at the [edit interfaces interface-name unit 0] hierarchy level. When you include the allow-any-vci statement, you cannot configure other logical interfaces in the same physical interface. Next, you must map unit 0 to an LSP using the CCC connection.

  4. To map unit 0 to an LSP:

  5. To map a VPI to an LSP, you must define the allowed VPIs. You can configure one or more logical interfaces, each mapped to a different VPI. You can then route traffic from each of these interfaces to different LSPs.
