Traffic shaping

Hi all,

I have a router on stick with Cisco 2551XM & Catalyst 2950-SI to manage 2 Class C networks (192.168.1.x/24 & 192.168.2.x/24).

Cisco 2651XM

|

Catalyst 2950 --- VLAN1 switch 192.168.1.x/24 (Catalyst 3550-SMI)

|

VLAN2 switch 192.168.2.x/24 (Catalyst 2950), -> not managed by me.

I want to limit certain users access to internet in 192.168.1.x, and no restriction to 192.168.2.x/24.

1. Can Catalyst2950-SI to perform this, instead of router (applying on trunk interface)? I want to avoid any effects 192.168.2.x users.

2. How about applying traffic shaping in per port basis, instead of ACL based ?

It seems that many QoS features are not available for Standard Image model.

Any ideas and helps will be greatly appreciated. Thank you.

Best regards,

b.go

Re: Traffic shaping

Correct - SI image won't cut it. Upgrade to EI OR Perhaps -

one of - (a) use second ethernet interface in 2651XM to the switch.

Or (b) Try GTS on subinterface (not sure if that will work or not)

Re: Traffic shaping

Hi, thanks for the reply. Yes I have applied/added the traffic shape for the sub interface. So how do I know if the traffic shaping is taking effect or not (for group 10 in this case). Below is the config for the output to internet interface.

interface Serial0/0

ip address ISP_ADD ISP_MASK

ip access-group 100 in

ip nat outside

encapsulation ppp

traffic-shape group 10 64000 8000 8000 1000

group 10 is the LAN that I want to control and group 100 is access for all LANs (including group 10 itself).

Many thanks for the ideas, and suggestions.

Best regards,

b.go
