Providing Session Limit Support
The PPP over Ethernet Session Limit feature enables you to limit the number of PPP over Ethernet (PPPoE) sessions that can be created on a router or on a Gigabit Ethernet interface for configuration.
Finding Feature Information
Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the Feature Information Table at the end of this document.

Information About Providing Session Limit Support
Benefits of Providing Session Limit Support
The PPPoE Session Limit feature prevents the router from using too much memory for virtual access by limiting the number of PPPoE sessions that can be created on a router or on all Ethernet interfaces and sub-interfaces as well as ATM interfaces and sub-interfaces.
How to Provide Session Limit Support
- Specifying the Maximum Number of PPPoE Sessions on the Router
- Specifying the Maximum Number of PPPoE Sessions on a Gigabit Ethernet Interface
Specifying the Maximum Number of PPPoE Sessions on the Router
Perform this task to specify the maximum number of PPPoE sessions that can be created on a router.
DETAILED STEPS
Specifying the Maximum Number of PPPoE Sessions on a Gigabit Ethernet Interface
Perform this task to specify the maximum number of PPPoE sessions that can be created on a Gigabit Ethernet interface.
DETAILED STEPS
Command or Action | Purpose | |||
---|---|---|---|---|
|
Example: Router> enable |
Enables privileged EXEC mode.
|
||
|
Example: Router# configure terminal |
Enters global configuration mode. |
||
|
Example: Router(config)# interface GigabitEthernet0/0/1 |
Specifies a Gigabit Ethernet interface and enters interface configuration mode. |
||
|
Example: Router(config-if)# pppoe enable group one |
Enables PPPoE sessions on a Gigabit Ethernet interface or subinterface.
|
||
|
Example: Router(config-if)# pppoe max-sessions 10 |
Specifies the maximum number of PPPoE sessions permitted on the interface or subinterface. The default value is 100. |
||
|
Example: Router(config-if)# end |
(Optional) Exits the configuration mode and returns to privileged EXEC mode. |
Configuration Examples for Providing Session Limit Support
- Specifying the Maximum Number of PPPoE Sessions on a Router Example
- Specifying the Maximum Number of PPPoE Sessions on a Gigabit Ethernet Interface Example
Specifying the Maximum Number of PPPoE Sessions on a Router Example
The following example shows a limit of 32,000 PPPoE sessions configured for the router:
bba-group pppoe global virtual-template 1 sessions per-mac limit 1000 sessions per-vlan limit 4000 inner 3500 sessions per-vc limit 2000
Specifying the Maximum Number of PPPoE Sessions on a Gigabit Ethernet Interface Example
The following example shows a limit of ten PPPoE sessions on the Gigabit Ethernet interface:
interface GigabitEthernet1/0/0 pppoe enable pppoe max-sessions 10
The following example shows a limit of ten PPPoE sessions on the Gigabit Ethernet subinterface using the encapsulationcommand:
interface GigabitEthernet0/0/0.1 encapsulation dot1q 2 pppoe enable pppoe max-sessions 10
