pado delay

To set a delay for a PPPoE Active Discovery Offer (PADO) message for a particular PPPoE BBA-Group, use the pado delay command in PPPoE BBA-Group configuration mode. To disable the PADO delay configuration, use the no form of this command.

pado delay delay

Syntax Description


`delay`	Delay value for PADO message, in milliseconds. The range is from 0 to 10000.

Command Default

None

Command Modes

PPPoE BBA-Group configuration

Command History


Release	Modification
Release 4.3.1	This command was introduced.

Usage Guidelines

Setting a value of 0 for delay means that no transmission delay is set for PADO message. Setting a value of 10000 means that an infinite delay is set for PADO message or in other words, PADO message is never sent.

pado delay circuit-id

To set a delay for a PPPoE Active Discovery Offer (PADO) message for a particular PPPoE BBA-Group, based on the Circuit-ID received in PPPoE Active Discovery Initiator (PADI) message, use the pado delay circuit-id command in PPPoE BBA-Group configuration mode. To disable the PADO delay configuration based on the Circuit-ID, use the no form of this command.

pado delay circuit-id {delay | {string | contains} string delay}

Syntax Description


`delay`	Delay value for PADO message, in milliseconds, based on the Circuit-ID. The range is from 0 to 10000.
string	Delays the PADO message, when the Circuit-ID string received in PADI message matches the configured `string` .
contains	Delays the PADO message, when the Circuit-ID received in PADI message contains the configured `string` .
`string`	String received in PADI message, that needs to be exactly matching the Circuit-ID (when used along with string keyword) or the string received in PADI message, that needs to be contained within the Circuit-ID (when used along with the contains keyword).

Command Default

None

Command Modes

Command History


Release	Modification
Release 4.3.1	This command was introduced.

Usage Guidelines

Setting a value of 0 for delay means that no transmission delay is set for the PADO message. Setting a value of 10000 means that an infinite delay is set for PADO message; or, in other words, the PADO message is never sent.

Within the category of Circuit-ID matches, full string matches are preferred to sub-string matches. If more than one sub-string match occur, the selection is based on a random order.

If there is neither a string match nor a sub-string match, the configured Circuit-ID delay is used (if a Circuit-ID is present in the PADI message), followed by the configured Remote-ID delay (if a Remote-ID is present in the PADI message).

If there are no matches, the configured pado delay is used for PADO message.

Command Default

Command Modes

Command History


Release	Modification
Release 4.2.0	This command was introduced.
Release 6.2.1	Modified the command to include global BBA-Group.

Usage Guidelines

BBA-Groups are configured globally (these are essentially configuration templates), containing the PPPoE configuration settings.

When this configuration changes to use a different BBA-Group, then all existing PPPoE sessions running under the interface are terminated.

Among the various BBA-Groups that can be configured on a router, one BBA-Group can be configured as a global BBA-Group. If the maximum limit for PPPoE sessions is set under pppoe bba-group global configuration, it indicates the limit for the total number of sessions on the node.

Note

For RP subscribers, the node is the complete chassis.
For LC subscribers, the node is the LC. For LC subscribers, each LC considers the maximum limit set by the global limit. But with multiple LC in the chassis, the session count in the chassis can be multiplied by the number of active LC.

To use a BNG-wide limit for LC based subscribers, you can use either bundles or pre authentication.

For a single member, when you are using bundles, the sessions are maintained on the RP and the control is moved to the RP for all sessions. The bba group limit applies to all sessions regardless to the number of line cards carrying subscribers:
```
interface GigabitEthernet0/0/0/0
bundle id 100 mode on
```
In a pre authentication method, when PADI is received, an authorization request is sent to AAA . An authorisation request determines the session count on radius for it to accept or reject the request. When the request is accepted, a PADO is sent. When the request is rejected the PADI is discarded and ignored.

Global BBA-Group support in BNG is subjected to these restrictions:

Currently global BBA-Group supports only configurations related to session limit, except AAA override configuration. For more details, see usage guidelines section of pppoe sessions limit command.
You cannot change the configuration at run time for global BBA-Group.
The global BBA-Group is not valid for subscriber redundancy group (SRG) in BNG, and hence the pppoe bba-group global command must not be used in BNG geo redundancy scenarios.

Command History


Release	Modification
Release 4.2.0	This command was introduced.
Release 4.3.1	The PPPoE sessions limit support was extended for mac access-interface , mac-iwf access-interface , inner-vlan , outer-vlan , vlan , and circuit-id-and-remote-id Support for the optional argument, threshold was added.
Release 6.2.1	Functionality was included to set a global PPPoE session limit, that is, a session limit for the entire router.

Usage Guidelines

If a session limit is configured after the limit has already been exceeded, the existing sessions are torn down until the number of sessions matches the configured limit.

If both mac limit and mac-iwf limit are configured, only IWF limit is used for IWF sessions, so that a higher IWF limit than the limit for non-IWF sessions can be used. The same is the case if both mac access-interface limit and mac-iwf access-interface limit are configured.

Note

The sessions outer-vlan limit command limits the sessions only in single VLAN tag scenarios. You must use the sessions vlan limit command, to limit the sessions in double VLAN tag scenarios; this limits the maximum number of sessions allowed for each inner VLAN and outer VLAN, for each access-interface.

In order to set a global PPPoE session limit, use the sessions max limit command under pppoe bba-group global configuration mode. The combined number of sessions on all individual BBA-Groups cannot exceed this global limit. For example, consider a configuration where the global limit is set as 250, the limit of BBA-Group 1 (say, bba1 ) is set as 100, and the limit of BBA-Group 2 (say, bba2 ) is set as 200. If 100 sessions are already created with bba1 , then only 150 sessions (that is, 250 -100) can be created with bba2 , even though bba2 has a session limit of 200. Similarly there can be different combinations of sessions with local BBA-Groups as long as the global session limit is not exceeded. For more details, see pppoe bba-group command.
