I am using a PacketShaper in my network. My bandwidth was 10Mbps and now i have updated it to 12Mbps. The problem is i dont have money to extend the licence. So I am thinking of a solution to use QoS on switches and routers for the rest of 2Mbps (few classes: maybe 2 or 3)!
My traffic flow is the following : core switch -> PIX firewall-> screen switch->screen router! The screen switches are 2950G and the screen router is 3845. I was thinking to make marking on screen switch and shaping on screen router (cause on firewalls i have VPNs ended thats why i just excluded core switches here). These devices are not doing complex things in the network, the router has only 2 BGP neighbours (no other routing protocol, only static routes). My question is, could I implement such thing? it will be a problem regarding memory for the specified devices? what are your suggestions? did somebody implemented this double solution with QoS and PacketShaper for shaping in his network? Thanks a lot!
