Need to policing / shapping Internet connection to priorize some traffic from specific host.
Cisco 1941 as core router
Multiple offices connected to a MPLS network through telco router
Each office have Internet connection (30Mb/30Mb)
VLAN on trunk port LAN side.
MPLS to VLANs must be full speed
VLAN to VLAN must be full speed
INTERNET to VLANs must be shaped.
As I understand it, shaping need to be egress, here g0/0/0 port. The idea is to throttle Internet at 30Mbits and later on do some sub-shaping of that 30Mbits.
Did an lab test to see if I can throttle internet connection down to 1Mbs, but it fail. I’m still downloading at 30Mbits, no throttling as expected. Something wrong because port is trunk ? Any workaround ? Is it broken by design ?
# Tag Traffic from Internet (MPLS need to be full speed) class-map match-any cmap-internet match input-interface GigabitEthernet0/1 # Throttle to 1Mbits policy-map pmap-internet class cmap-internet shape average 1024000 # Hopefully throttle VLANs total bandwidth to INTERNET at 1Mbits and allow full speed VLAN-to-VLAN and VLANs-to-MPLS interface g0/0/0 service-policy out pmap-internet

If you are testing download speed you will need to change to service-policy in pmap-internet on the external interface ( gig 0/0/0). Alternatively you can do service-policy out pmap-internet on gig 0/1.

Paul,
Terminology: I use word "download" for workstation using speedtest.net on LAN point of view where external interface is g0/1 and internal is g0/0/0.
Data from Internet that goest IN g0/1 to Lan workstation OUT g0/0/0 trunk (Vlan1). Policing need to be egress, so "service-policy out pmap-internet" on g0/0/0
unfortunatly I still get 30Mbits
# Tag Traffic from Internet (MPLS need to be full speed) class-map match-any cmap-internet match input-interface GigabitEthernet0/1 ! # Throttle to 1Mbits policy-map pmap-internet class cmap-internet shape average 1024000 ! interface GigabitEthernet0/1 description INTERNET ip address 1.1.1.1 255.255.255.248 ... ! interface GigabitEthernet0/0/0 description Trunk LAN switchport mode trunk no ip address service-policy out pmap-internet ... ! interface Vlan1 description LAN ip address 10.101.1.1 255.255.255.0 ...
