Supported on all 7210 SAS platforms as described in this document.
The p2mpbud p2mpbud-port-id parameter is supported only on the 7210 SAS-R6 and 7210 SAS-R12. It reserves a loopback port for use with the NG-MVPN P2MP LSP feature.
This command specifies the port to assign for system use when using port loopback with the following tools: mac-swap, mirroring, testhead OAM, and NG-MVPN, when the node is acting as a P2MP bud router on the 7210 SAS-R6 or 7210 SAS-R12. When configured, the system uses the resources of the port, and the port is not available for configuring services.
A single port cannot be shared among these tools simultaneously. The system displays an error if users attempt to configure the same port for use with multiple OAM tools or use the tool without first configuring the port resources for the tool.
To use these OAM tools simultaneously, this command must be executed once for each OAM tool with a different port ID. For example, users can dedicate two ports for use by executing the loopback-no-svc-port mirror 1/1/1 command for use with the mirroring OAM tool, followed by the loopback-no-svc-port mac-swap 1/1/2 command for use by the mac-swap OAM tool.
Alternatively, users can dedicate two ports by executing the loopback-no-svc-port testhead 1/1/1 command for use by the testhead OAM tool, followed by executing the loopback-no-svc-port mac-swap 1/1/2 command for use by the mac-swap OAM tool.
The system verifies whether any services are configured on the port specified using this command; if services are configured, the command fails.
The no form of this command disables the use of this port by the specified OAM tool.
On the 7210 SAS-T, the two available internal ports (that is, port 1/1/27 and 1/1/28) can be used with the mac-swap, mirroring, or testhead OAM tool. To use the OAM tools simultaneously, an additional front-panel port must be configured for use with each of the tools.
On the 7210 SAS-R6 and 7210 SAS-R12, a fixed number of internal ports are available for use with OAM tools (such as, the testhead, mac-swap, and dot1q or remote mirroring OAM tool) that need the resources of a loopback port. The number of internal virtual port resources that are available on different types of IMMs can be obtained using the show system internal-loopback-ports detail command. If all the internal port resources are in use, users may need to configure the resources of a front-panel port for use with OAM tools that need loopback port resources. To use the OAM tools simultaneously, an additional front-panel port must be configured for use with each of the tools.
When configuring internal port resources or front-panel port resources for testhead and mac-swap OAM tools, the port must be on the same IMM as the test SAP.
On the 7210 SAS-Mxp, one internal port (that is, port 1/1/29) is available for use with the mac-swap, mirroring, or testhead OAM tool. To use the OAM tools simultaneously, an additional front-panel port must be configured for use with each of the tools.
Specifies that the loopback port (in the slot/mda/port format) is dedicated for use by the mac-swap OAM tool.
Specifies that the loopback port (in the slot/mda/port format) is dedicated for use by the mirroring OAM tool.
Specifies that the loopback port (in the slot/mda/port format) is dedicated for use by the testhead OAM tool.
Specifies the loopback port (in the slot/mda/port format) to use for P2MP LSP, which is used with NG-MVPN feature. Applicable only to 7210 SAS-R6 and 7210 SAS-R12 devices.
Keyword to enable ingress FC classification for packets that are received on a P2MP LSP on a network port IP interface and that are replicated to IP multicast receivers. This keyword allows users to prioritize multicast traffic to IP receivers in the service. In addition, it enables the capability to mark the packet with IP DSCP values while sending the multicast stream out of the IP interface. Applicable only to 7210 SAS-R6 and 7210 SAS-R12 devices.
Before using this keyword, users must ensure that sufficient resources are available in the network ingress CAM resource pool and MPLS EXP ingress profile map resource pool. Use the tools>dump>system-resources command to check resource availability.
