1.1 EPON System Configuration Commands

1.1.1 auto-authorize-onu enable

Syntax

auto-authorize-onu enable

undo auto-authorize-onu enable

View

FTTH view

Parameter

None

Description

Use the auto-authorize-onu enable command to enable automatic ONU (optical network unit) authentication.

Use the undo auto-authorize-onu enable command to disable automatic ONU authentication.

l If automatic ONU authentication is enabled, an ONU tries to register and join the EPON system automatically once it is powered on. And after the ONU joins the EPON, it can communicate with the optical line terminal (OLT) without binding the ONU port and the ONU MAC address.

l If the automatic ONU authentication is disabled, ONUs can still register with the EPON system successfully, but you need to bind ONU ports and the ONU MAC addresses manually for the ONUs to communicate with the OLT.

By default, automatic ONU authentication is disabled.

Caution:

Due to security consideration, automatic ONU authentication is currently not supported.

Example

# Enter system view.

<H3C> system-view

# Enter FTTH view.

[H3C] ftth

# Enable automatic ONU authentication.

[H3C-ftth] auto-authorize-onu enable

This operation is not supported in current version!

1.1.2 display epon-capability

Syntax

display epon-capability interface interface-type interface-number

View

Any view

Parameter

interface-type: Port type, which can be OLT or ONU.

interface-number: OLT/ONU port number.

& Note:

As for the interface-number argument, the format of LPU slot number/sub-LPU slot number/OLT port number is used for OLT ports; and the format of LPU slot number/sub-LPU slot number/OLT port number:ONU port number is used for ONU ports.

Description

Use the display epon-capability command to display OLT or ONU capability information.

l If interface-type interface-number identifies an OLT port, the following information about the OLT is displayed: automatic gain control (AGC) creation time and clock data recovery (CDR) locking time.

l If interface-type interface-number identifies an ONU port, the following information about the ONU is displayed: laser on time, laser off time, and grant FIFO deep.

Caution:

Before displaying the capability information about an ONU, make sure the ONU is bound and is in UP state (refer to the bind onuid command for more). Before displaying the capability information about an OLT, make sure the OLT is in UP state.

& Note:

l Because location distance and external conditions of each ONU are different, the received signal maybe strong or weak. AGC creation time is used to automatically restore signal strength so that the signal can be received.

l CDR locking time is used to recover clock data.

l An ONU laser on time is the period within which an ONU laser is opened until stabilizing, An ONU laser off time is the period within which an ONU laser is shut off until stabilizing.

Example

# Display Olt2/0/8 version information.

<H3C> display epon-capability interface olt2/0/8

2.1.4 igmp-to-cpu enable

Syntax

igmp-to-cpu enable

undo igmp-to-cpu enable

View

OLT port view, FTTH view

Parameter

None

Description

Use the igmp-to-cpu enable command to enable IGMP packets to be passed to CPU for being processed.

Use the undo igmp-to-cpu enable command to disable IGMP packets from being passed to CPU.

These two commands apply to the current OLT if they are executed in OLT port view and apply to all the OLTs if they are executed in FTTH view.

By default, IGMP packets are passed to CPU for being processed.

Caution:

The OLT may operate improperly if you enable IGMP packets to be passed to CPU for it and an ONU forward uplink multicast packets to the OLT.

Example

# Disable IGMP packets from being passed to CPU.

<H3C> system-view

2.1.5 max-rtt

Syntax

max-rtt value

undo max-rtt

View

OLT port view

Parameter

value: Maximum round trip time (RTT) to be set. This argument ranges from 1,000 to 25,000 (in TQs). The system default maximum RTT is 13,524 TQs.

Description

Use the max-rtt command to set the maximum RTT.

The ONUs are usually at different distances from the OLT. Therefore, they have different RTT values. Through the configuration of the maximum RTT, you can limit the registration of the ONUs that are relatively farther away from the OLT.

RTT is figured out as follows.

Suppose that an OLT sends a time stamp T0 to an ONU at the time T0. Once the ONU receives the time stamp, it sets its local timer to T0. After waiting for a specific period, the ONU sends a time stamp T1 to OLT at the time T1. The OLT receives this stamp at the time T2.

Then, the RTT of the ONU can be obtained by using the following expression:

(T2 - T0) - (T1 - T0).

Caution:

l These two commands are recommended to users with administrative rights only.

l This command takes effect only on unregistered ONUs. It does not take effect on registered ONUs.

l The RTT value of a registered ONU cannot be zero. You need to lengthen the optical cable by at least 20 meters for registered ONUs with the RTT being zero. To obtain the RTT of an ONU, use the display onuinfo interface command.

Example

# Enter system view.

<H3C> system-view

# Enter Olt2/0/8 port view.

[H3C] interface olt2/0/8

# Set the maximum RTT to 25,000 TQs.

[H3C-Olt2/0/8] max-rtt 25000

2.1.6 port permit vlan

Syntax

port permit vlan vlan-list

undo port permit vlan vlan-list

View

OLT port view

Parameter

vlan-list: VLAN ID list. This argument can be a VLAN ID list (which can contain up to ten VLAN IDs) or a VLAN ID range (in the form of vlan-id to vlan-id). VLAN ID here ranges from 2 to 4094.

Description

Use the port permit vlan command to specify the VLANs whose packets are permitted by an OLT port, through which you can suppress unnecessary VLAN broadcast.

Use the undo port permit vlan command to specify the VLANs whose packets are denied by an OLT port.

By default, the packets of VLAN 1 are permitted by all the OLT port.

Note that, VLAN configuration for an OLT port is needed only when the VLAN tag processing mode of an ONU port is transparent. If the VLAN tag processing mode of an ONU port is untagged, the OLT port permits the packets of the VLAN automatically. In this case, VLAN configuration of the OLT port is not needed.

Related command: port handlemode.

Example

# Enter system view.

<H3C> system-view

# Enter Olt2/0/8 port view.

[H3C] interface olt2/0/8

# Configure to permit the packets of VLAN 2.

[H3C-Olt2/0/8] port permit vlan 2

Chapter 3 ONU Configuration Commands

Parameter

downstream: Specifies the configuration is for downstream data flows from OLT to ONU.

policy: Specifies to enable/disable bandwidth allocation policy.

max-bandwidth value: Specifies the maximum bandwidth in Kbps. The value argument ranges from 0 to 1,000,000 and defaults to 1,000,000.

max-burstsize value: Specifies the maximum burst buffer size in bytes. The value argument ranges from 0 to 8,388,480 and defaults to 8,388,480.

high-priority: Specifies to enable/disable high-priority frames to take precedence. This policy is disabled by default.

short-frame: Specifies to enable/disable short-frames to take precedence. This policy is disabled by default.

Description

Use the bandwidth command to configure the bandwidth allocation policy and bandwidth limitation.

Use the undo bandwidth command to cancel the configured bandwidth allocation policy and restore the default bandwidth limitation.

By default, the downstream bandwidth allocation policy is disabled.

Caution:

Currently, this command is not supported.

Example

# Enable bandwidth allocation policy for downstream data flows.

[H3C] interface onu 2/0/8:1

[H3C-Onu2/0/8:1] bandwidth downstream policy enable

This operation is not supported in current version!

3.1.2 bind onuid

Syntax

bind onuid onuid [ type { et204 | et300 | ls6m1pu1s } ]

undo bind onuid

View

ONU port view

Parameter

onuid onuid: Specifies the MAC address of the ONU to be bound to. The onuid argument is in dotted hexadecimal notation (that is, in the H-H-H form). You can obtain the MAC address of an ONU by using the display onuinfo interface command. Refer to section “2.1.2 display onuinfo interface” for details.

type: Specifies the type of the ONU, which can be et204 (corresponding to ET204/ET204-L20), et300 (corresponding to ET300/ET300-L20), and ls6m1pu1s (corresponding to ONU sub-card LS6M1PU1SA or LS6M1PU1SB). If you do not use the type keyword, the type is ET204 by default.

Description

Use the bind onuid command to bind the current ONU port to an ONU of a specified type by associating the ONU port with the MAC address of the ONU. The OLT can manage the ONU only after you bind an ONU port to the ONU.

Use the undo bind onuid command to unbind the ONU port from the ONU. The unbinding operation invalidates all related configuration for the ONU.

& Note:

l After you bind an ONU port to an ONU, the ONU is still in the down state. You can use the undo shutdown command to bring it up.

l For an unregistered ONU, if the specified ONU type does not match the actual ONU type, a warning message will appear after the ONU is powered on and successfully registers with the OLT, indicating that the binding type does not match the actual one. For a registered ONU, if the specified ONU type does not match the actual ONU type, you will be prompted immediately that the binding type does not match the actual one.

Caution:

An ONU port can only be bound to one ONU MAC address. Conversely, an ONU MAC address can only be bound to one ONU port.

Example

# Bind the Onu2/0/8:1 port to a sub-card ONU with MAC address 00e0-fc00-0001. (The bindings to other types of ONUs are similar).

3.1.3 dba-algorithm

Syntax

dba-algorithm { enable { extdba | intdba } | update filename }

View

OLT port view

Parameter

enable: Enables a dynamic bandwidth allocation (DBA) algorithm.

extdba: Specifies to enable the external DBA algorithm.

intdba: Specifies to enable the internal DBA algorithm.

update: Upgrades the external algorithm with a DBA algorithm file.

filename: Device name + DBA algorithm file name, a string of up to 64 characters. Note that the DBA algorithm file on the backup SRPU cannot be used for upgrade.

Description

Use the dba-algorithm command to enable the internal or external DBA algorithm, or upgrade the external DBA algorithm.

By default, the internal DBA algorithm is enabled.

Caution:

l You can manually load an external DBA algorithm by using the dba-algorithm update command as needed.

l When you use the dba-algorithm update command to upgrade the external DBA algorithm, the new upgrade file is synchronously loaded onto the backup SRPU (switching and routing process unit), and overwrites the old one (if any) in the backup SRPU. If the synchronous upgrading operation fails (this may occur when there is not enough free space on the FLASH of the backup SRPU), DBA algorithms on the primary and backup SRPUs will be different, thus resulting in configuration errors.

Example

# Load an external DBA algorithm.

<H3C> system-view

[H3C] interface olt 2/0/8

[H3C-Olt2/0/8] dba-algorithm update plato2.app

Parameter

discovery-frequency value: Specifies the cycle for the OLT to send discovery frames to ONUs (the cycle is known as grant cycle, which is measured in cycle-length). The value argument ranges from 25 to 100; it defaults to 50 if you do not use the discovery-frequency keyword.

discovery-length value: Specifies the period in TQs for the OLT to discover ONUs. The value argument ranges from 21,845 to 87,381 and defaults to 41,500.

cycle-length value: Specifies the cycle-length in TQs (cycle-length is the measurement unit of grant cycle). The value argument ranges from 32,768 to 131,070; it defaults to 65,535 if you do not use the cycle-length keyword.

& Note:

For an example, if you set the grant cycle to 30 with the discovery-frequency keyword, the OLT periodically sends discovery frames to ONUs at the interval of 30 x cycle-length.

Description

Use the dba-parameters command to set DBA parameters.

Use the undo dba-parameters command to restore the default DBA parameter values.

Caution:

The two commands are designed to be used by users with administrator privilege. General users are not recommended to use them.

3.1.12 multicast-filter enable

Syntax

multicast-filter enable

undo multicast-filter enable

View

ONU port view

Parameter

None

Description

Use the multicast-filter enable command to enable multicast filtering for the ONU under the ONU port.

Use the undo multicast-filter enable command to disable multicast filtering for the ONU.

An ONU can automatically learn multicast MAC addresses. Multicast filtering enables an ONU to filter out multicast frames whose multicast MAC addresses are not contained in the multicast MAC address table of the ONU.

With multicast filtering enabled for an ONU, downstream multicast frames from the OLT to the ONU will be discarded if their multicast MAC addresses are not contained in the multicast MAC address table of the ONU. With multicast filtering disabled for an ONU, all downstream multicast frames will be transparently transmitted.

Multicast filtering is disabled by default.

& Note:

l This command only applies to ET204, ET204-L20, ET300, and ET300-L20.

l Aolynk ET series optical terminals support up to eight learned or manually configured multicast MAC addresses (the manually configured multicast MAC addresses are in the range of 01-00-5e-00-01-00 to 01-00-5e-7f-ff-ff). A downstream frame with the first 16 bits in the least significant 24 bits of its multicast MAC address being zero (such as 01-00-5E-00-00-XX) will be transparently transmitted.

Example

# Enable multicast filtering for the ONU under Onu2/0/8:1.

<H3C> system-view

[H3C] interface onu 2/0/8:1

[H3C-Onu2/0/8:1] multicast-filter enable

3.1.13 port handlemode

Syntax

port handlemode { untagged | transparent }

undo port handlemode

View

ONU port view

Parameter

untagged: Specifies the untagged mode. In this mode, you can configure a VLAN for the port so that the port belongs to the VLAN. After that, for a downstream frame from the OLT to the ONU, if the frame belongs to the same VLAN as that configured on the ONU port, the ONU port removes the VLAN tag from the frame header and continues to forward the frame, otherwise it discards the frame. For an upstream frame from the ONU to the OLT, if the frame does not contain a VLAN tag, the ONU port inserts the VLAN tag configured on it into the frame header before forwarding the frame (for example, if the ONU port belongs to VLAN 2, the ONU port inserts the tag of VLAN 2 into the frame). Otherwise, the frame is sent to the OLT without being modified.

transparent: Specifies the transparent mode. In this mode, for an upstream frame, if the fame does not carry a VLAN tag, the ONU port inserts the tag of VLAN 1 into the frame before forwarding it to the OLT; if the frame carries a VLAN tag, the ONU port forwards the frame directly. For downstream frames, the ONU port remains them unchanged and forwards them directly.

Description

Use the port handlemode command to set the VLAN tag processing mode.

Use the undo port handlemode command to restore the default VLAN tag processing mode.

An ONU port can operate in one of the two modes to process VLAN tags: transparent and untagged. It operates in untagged mode by default.

Caution:

This command only applies to ET204, ET204-L20, ET300, and ET300-L20.
