flash set OMCI_VEIP_SLOT_ID Configuration

Reference: GitHub Issue Comment by rajkosto

Overview

The flash set OMCI_VEIP_SLOT_ID command controls the Virtual Ethernet Interface Point (VEIP) Slot ID within the Optical Network Unit (ONU) configuration. While your initial description provides a starting point, the GitHub user has contributed additional insights to enhance the understanding and usage of this command.

Parameters

  • VEIP EntityID Calculation: The value for OMCI_VEIP_SLOT_ID should be set to the Most Significant Bit (MSB) of the desired VEIP EntityID. For example, if the VEIP EntityID is 0x0e01, set OMCI_VEIP_SLOT_ID to 0x0e or 14 (decimal).

Enabling Customized VEIP Slot ID

The GitHub user emphasizes that the feature to apply the custom VEIP Slot ID is not enabled by default. To activate this feature, follow these steps:

  1. Set bit 0x100 in OMCI_CUSTOM_ME to enable the cf_apply_customized_veip_slot_id feature.
  2. The default value in SFU firmwares for OMCI_CUSTOM_ME is 65536. Set it to 65792 to enable the feature.

Before Configuration Example:

# omcicli mib get 329
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
VEIP
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
=================================
EntityId: 0x0601
AdminState: 1
OperState: 1
InterDomainName: 0x00000000000000000000000000000000000000000000000000
TcpUdpPtr: 0x0000
IansAssignPort: 0
CustomizedSlotId: 0xff
=================================

After Configuration Example:

# omcicli mib get 329
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
VEIP
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
=================================
EntityId: 0x0e01
AdminState: 1
OperState: 1
InterDomainName: 0x00000000000000000000000000000000000000000000000000
TcpUdpPtr: 0x0000
IansAssignPort: 0
CustomizedSlotId: 0x0e
=================================

Take note on EntityId and CustomizedSlotId

Understanding the Transformation: 65536 to 65792

In the context of configuring the Optical Network Unit (ONU) using the flash set OMCI_VEIP_SLOT_ID command, there is a specific parameter called OMCI_CUSTOM_ME that plays a crucial role. The GitHub user @rajkosto recommends setting a bit, specifically bit 0x100, in the OMCI_CUSTOM_ME to enable a particular feature (cf_apply_customized_veip_slot_id).

Initial Value of OMCI_CUSTOM_ME: 65536

The default value for OMCI_CUSTOM_ME in SFU firmwares is given as 65536. This value is represented in hexadecimal as 0x10000.

Adding 0x100 to Enable the Feature

To enable the cf_apply_customized_veip_slot_id feature, it is necessary to set bit 0x100 in OMCI_CUSTOM_ME. Adding 0x100 to the initial value transforms it as follows:

  Initial Value: 0x10000 (65536 in decimal)
+  Bit Addition: 0x00100
  _______________________
  Result:        0x10100 (65792 in decimal)

Final Value of OMCI_CUSTOM_ME: 65792

Therefore, by adding 0x100 to the default value of OMCI_CUSTOM_ME, the final value becomes 65792. This modified value activates the feature, allowing the cf_apply_customized_veip_slot_id functionality in the ONU configuration.

Understanding this transformation is crucial for users who wish to customize and enable specific features related to the VEIP Slot ID configuration.
