Cisco Cisco IOS Software Release 12.2(2)DD

To limit the number of sessions that are allowed through a specified VPDN group, use the session-limit 
command in VPDN configuration mode. To remove a configured session-limit restriction, use the no 
form of this command.

no session-limit number

No default behavior or values.

VPDN configuration

Use this command to limit the number of allowed sessions for a specified VPDN group.

This command works independently from the global VPDN session-limit command. Using the global 
VPDN session-limit command, you can restrict the total number of sessions allowed on all VPDN 
groups. Global session limiting is configured in configuration mode. VPDN group session limiting is 
configured in VPDN configuration mode. 

Global VPDN session limiting and per VPDN group session limiting work independently, but global 
VPDN session limiting is enforced before individual VPDN group limiting. For example, if you 
configure vpdn session-limit 2 at the global configuration mode and session-limit 3 under the VPDN 
group “abc,” no more than two calls are allowed in VPDN group “abc.”

The following example creates VPDN group “abc,” virtual template 5, and restricts VPDN group “abc” 
to three sessions:

Router(config)# vpdn-group abc

Router(config-vpdn)# accept dialin

Router(config-vpdn-acc-in)# protocol l2tp

Router(config-vpdn-acc-in)# virtual-template 5

Router(config-vpdn-acc-in)# exit

Router(config-vpdn)# terminate hostname host1

Router(config-vpdn)# session-limit 3

Specifies the number of sessions allowed through a specified VPDN group.
