Virtual-Access session limit (PPPoE)

[farhadsoltani]

Hi,

I have a 3640 (IOS:12.3(1)) and ACS for Broadband service. I use PPPoE for users. When I entered "SHOW USERS" it show users with interfaces. all interfaces are Vi1 till Vi6. I have no more than 4 online users right now. I have a question: If I have more than 6 users, can they connect to access server? Because router has only 6 Virtual-access interfaces. I tested it with another 3640 without ACS but users use Vi1.1 (subinterface). It is very important for me.

Hi,

How many Virtual_Templates are configured on your system? If only 1 then as users connect the will be assigned a Vi of 1.1, 1.2, 1.3, etc.....let me know what your config is like.

Hi Ramos,

Thank you for your reply. I tested it on another C3640 with same configuration but users take Vi2.1! I have only 1 Virtual-Template.

this is my configuartion:

vpdn-group PPPoEoE

accept-dialin

protocol pppoe

virtual-template 1

lcp renegotiation always

interface Virtual-Template1

ip unnumbered FastEthernet0/0

no ip redirects

no ip unreachables

no ip proxy-arp

ip mtu 1492

ntp disable

peer default ip address pool PPPOE

ppp authentication pap FRSO

ppp authorization ADAUT

ppp accounting acct

It works normaly in my lab but does not work in network! (My lab has no ACS)

Hi Farhad,

I know how that is, works in the lab but not outside the lab...hahahaha....Ok have you tried connecting more than 4 users?

Basicallyt I run a similar setup with 1 Virtual template configured on my router and as users are logged in each one gets assigned its own interface or subinterface under that Virtual-Template configuration. I dont see where acs would limit this unless you have some boundries set-up that I am not aware of, I hope this helps you.

Hi,

I solved it!

remove "ntp disable" from Virtual-Template 1.

and all users take Vi2.x

Thank you very much.
