[c-nsp] Multicast restriction.

[Sergey Velikanov [Intelsoft]]

I'm trying separate ipTV's channels to free and payed, on cisco.com I've found two methods

1)
ip igmp profile 10
     permit
     range 224.1.1.3 224.1.1.3			! free channel
     range 224.2.127.254 224.2.127.254     ! sap

interface FastEthernet0/42
   description Client (only free channels + sap)
   switchport access vlan 142
   ip igmp filter 10

2)
access-list 80 permit 224.2.127.254
access-list 80 permit 224.1.1.3

interface Vlan142
  ip address x.x.x.x
  ip pim sparse-mode
  ip igmp access-group 80

Is any difference between "ip igmp filter" and "ip igmp access-group" except first applied on L2 interface and second applied on L3 interface?

PS: I'm using catalyst 3560, and every users have their own vlans and own L2 ports.
