config>service>ies>sub-if>grp-if>pppoe
config>service>vprn>sub-if>grp-if>pppoe
Description 

This command creates a text description stored in the configuration file for a configuration context.

The description command associates a text string with a configuration context to help identify the content in the configuration file.

The no form of this command removes the string from the configuration.

Default 

no description

Parameters

Syntax 
[no] shutdown
Context 
config>service>ies>sub-if>grp-if>pppoe
config>service>vprn>sub-if>grp-if>pppoe
Description 

This command administratively disables an entity. When disabled, an entity does not change, reset, or remove any configuration settings or statistics.

The operational state of the entity is disabled as well as the operational state of any entities contained within. Many objects must be shut down before they may be deleted.

The no form of this command places the entity into an administratively enabled state.

ppp-policy

Syntax 
ppp-policy ppp-policy-name [create]
no ppp-policy ppp-policy-name
Context

Syntax 
[no] accept-mrru
Context 
config>subscr-mgmt>ppp-policy>mlppp
Description 

This command is applicable only to LAC. MRRU option is an indication that the session is of MLPPPoX type. The 7750 SR LAC will never initiate MRRU option in LCP negotiation process. However, it will respond to MRRU negotiation request by the client.

This command provides an option to specifically enable or disable negotiation of MLPPPoX on a capture SAP level or on a group interface level.

The no form of the command causes the MRRU option in LCP will not be negotiated by LAC.

Default 

no accept-mrru

admin-state

Syntax 
admin-state {up | down}
no admin-state
Context 
config>router>l2tp>group>tunnel>mlppp
config>service>vprn>l2tp>group>tunnel>mlppp
Description 

This command is applicable only to LNS.

The tunnel can be explicitly activated (assuming that the parent group is in a no shutdown state) or deactivated by the up and down keywords.

If case that there is no admin-state configured, the tunnel will inherit its administrative state from its parent (group).

The no form of the command causes the tunnel administrative state to be inherited from the group.

Default 

no admin-state

Parameters 
up—
Specifies that the tunnel is to be administratively up.
down—
Specifies that the tunnel is to be administratively down.

encap-offset

Syntax 
encap-offset [type encap-type]
no encap-offset
Context 
config>subscriber-mgmt>loc-user-db>ppp>host>access-loop
Description 

This command is applicable within the LAC/LNS context. It provides the last mile link encapsulation information that is needed for proper (shaping) rate calculations and interleaving delay in the last mile.

The encapsulation value will be taken from the following sources in the order of priority:

  1. Statically provisioned value in local user database (LUDB).
  2. RADIUS
  3. PPPoE tags on LAC or ICRQ message (RFC 5515) on LNS

In case that the encapsulation information is not provided by any of the existing means (LUDB, RADIUS, AVP signaling, PPPoE Tags), then by default pppoea-null encapsulation will be in effect.

The following values are supported encapsulation values on LNS in the 7750 SR.

encap-type:

pppoa-llc LLC (NLPID) PPPoA encapsulation.

pppoa-null

VC-MUX PPPoA encapsulation.

pppoeoa-llc

config>router>l2tp>group>tunnel>mlppp
config>service>vprn>l2tp>group>mlppp
config>service>vprn>l2tp>group>tunnel>mlppp
config>subscr-mgmt>ppp-plcy>mlppp
Description 

When configured under the l2tp hierarchy, this command is applicable to LNS.

Within the ppp-policy, this command is applicable only to LAC.

The endpoint, according to RFC 1990, represents the system transmitting the packet. It is used during MLPPPoX negotiation phase to distinguish this peer from all others.

In the case that the client rejects the endpoint option during LCP negotiation, the LAC and the LNS must be able to negotiate the LCP session without the endpoint option.

The no form of this command disables sending endpoint option in LCP negotiation.

Default 

no endpoint

Parameters 
ip ip-address—
Specifies the IPv4 address (class 2)
system-ip—
Specifies to use the system IPv4 address (class 2)
mac ieee-address—

This command is applicable only to LNS. Interleaving is supported only on MLPPPoX bundles that contain a single member link. If more than one link is present in the MLPPPoX bundle, interleaving will be automatically disabled and a TRAP/log (tmnxMlpppBundleIndicatorsChange) will be generated.

The minimum supported rate of the link on which interleaving is performed is 1kbps.

If configured at this level, interleaving will be enabled on all tunnels within the group, unless it is explicitly disable per tunnel.

Default 

no interleave — Interleaving per group is disabled.

interleave

Syntax 
interleave {always | never}
no interleave
Context 
config>router>l2tp>group>tunnel>mlppp
config>service>vprn>l2tp>group>tunnel>mlppp
Description 

This command is applicable only to LNS. Interleaving is supported only on MLPPPoX bundles that contain a single member link. If more than one link is present in the MLPPPoX bundle, interleaving will be automatically disabled and a TRAP/log (tmnxMlpppBundleIndicatorsChange ) will be generated.

The minimum supported rate of the link on which interleaving is performed is 1kbps.

Interleaving configured on this level will overwrite the configuration option under the group hierarchy. If the no form of the command is configured for interleaving at this level, the interleaving configuration will inherit the configuration option configured under the l2tp group.

Default 

no interleave — Interleaving configuration is inherited from the group.

Parameters 
always—
Always perform interleaving on single linked MLPPPoX sessions within this tunnel, regardless of the configuration option for interleaving under the group level.
never—
Never perform interleaving on single linked MLPPPoX sessions within this tunnel, regardless of the configuration option for interleaving under the group level.

load-balance-method

Syntax 
load-balance-method {session | tunnel}
no load-balance-method
Context 
config>router>l2tp>group
config>router>l2tp>group>tunnel
config>service>vprn>l2tp>group
config>service>vprn>l2tp>group>tunnel
Description 

This command is applicable only to LNS. By default traffic load balancing between the BB-ISAs is based on sessions. Each session is individually assigned to an BB-ISA during session establishment phase.

By introducing MLPPPoX, all sessions of a bundle must be terminated on the same LNS BB-ISA. This is necessary for two reasons:

  1. QoS in the carrier IOM has a uniform view of the subscriber
  2. a single BB-ISA is responsible for MLPPPoX encapsulation/fragmentation for a given bundle.

Therefore, if fragmentation is enabled, load-balancing per tunnel must be configured. In the per tunnel load-balancing mode, all sessions within the same tunnel are terminated on the same LNS BB-ISA.

In the case that we have MLPPPoX sessions with a single member link, both load-balancing methods are valid.

The no form of this command sets the per session load balancing.

Default 

session — The per session load balancing is enabled by default.

Parameters 
session—
The traffic load balancing between the LNS BB-ISAs is based on individual PPPoE sessions.
tunnel—
The traffic load balancing between the LNS BB-ISAs is based on tunnels.

max-fragment-delay

Syntax 
max-fragment-delay delay
no max-fragment-delay
Context 
config>router>l2tp>group>mlppp
config>router>l2tp>group>tunnel>mlppp
config>service>vprn>l2tp>group>mlppp
config>service>vprn>l2tp>group>tunnel>mlppp
Description 

This command is applicable only to LNS. It determines the maximum fragment delay caused by the transmission that will be imposed on a link.

Fragmentation can be used to interleave high priority packet in-between low priority fragments on a MLPPPoX session with a single link or on a MLPPPoX session with multiple links to better load balance traffic over multiple member links.

Default 

no max-fragment-delay — Fragmentation is disabled.

Parameters 
delay—
Specifies the interval in milliseconds.
Values—
5 to 1000ms

max-link

Syntax 
max-links max-links
no max-links
Context 
config>router>l2tp>group>mlppp
config>router>l2tp>group>tunnel>mlppp
config>service>vprn>l2tp>group>mlppp
config>service>vprn>l2tp>group>tunnel>mlppp
Description 

This command is applicable only to LNS. It determines the maximum number of links that can be put in a bundle.

Any attempt of a session to join a bundle that is above the max-link limit will be rejected.

If interleaving is configured, it is recommended that max-links be set to 1 or a version of the command is used (no max-links). Both have the same effect.

The configuration under the tunnel hierarchy will override the configuration under the group hierarchy.

The no form of this command limits the number of links in the bundle to 1.

Default 

no max-links — A single link per bundle is allowed.

Parameters 
max-links—
Specifies the maximum number of links in a bundle.
Values—
1 to 8

config>router>l2tp>group>tunnel>mlppp
config>service>vprn>l2tp>group>mlppp
config>service>vprn>l2tp>group>tunnel>mlppp
Description 

This command is applicable only to LNS. It determines the time during which the LNS keeps fragments of the same packet in the buffer before it discards them. The assumption is that if the fragments do not arrive within certain time, the chance is that they were lost somewhere in the network. In this case the partial packet cannot be reassembled and all fragments that has arrived up to this point and are stored in the buffer will be discarded in order to free up the buffer. Otherwise, a condition will arise in which partial packets will be held in the buffer until the buffer is exhausted.

The configuration under the tunnel hierarchy will override the configuration under the group hierarchy.

The no form of this command sets the timeout to 1000ms.

Default 

1000

Parameters 
timeout—
Specifies the reassembly timeout value.
Values—
100, 1000 milliseconds
