Rate Limit on 3650

[BashedRoot]

I have a few dedicated server clients that use excessive amount of bandwidth, even on 100mbit port speed. I'd like to find a middle ground to keep things stable. Can someone please explain in simple, command to command terms how to set a rate limit on a VLAN port, say for example 50Mbps or 25Mbps? I'd appreciate it. Thank you.

Hi,

on 3650 QoS is quite similar to router's QoS, here you can find some useful tip and config example: http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3650/software/release/3e/qos/configuration_guide/b_qos_3e_3650_cg/b_qos_3se_3650_cg_chapter_011.html#concept_53FE327EBFE141D88A4ABEF889E143ED

The document is over my head. I was hoping for a simplified way to just apply something in between 10-100Mbps speed like 25 or 50.

I made this configuration on a 3560:

ip access-list extended MyServer
permit ip host 10.10.10.10 any

!

class-map match-all MyServer-CMAP
match access-group name MyServer
!
policy-map PoliceServer-PMAP
class MyServer-CMAP
police 25000000 8000 exceed-action drop
class class-default

!

interface FastEthernet0/1
service-policy input PoliceServer-PMAP

On the 3560 i can't police on the vlan interface maybe the the 3650 can, try it out, and let us know if it works.

Hi,

consider also shaping; I  usually prefer to shape because it's more "smooth" in regulating the bandwidth. The config is the same rasmus give you just use

• shape average target _bit_rate

or

• shape average interf_BW_percent     
  

instead of police

Yes I found that here http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3650/software/release/3e/qos/configuration_guide/b_qos_3e_3650_cg/b_qos_3se_3650_cg_chapter_011.html#task_6C85007887484ED29B900A3F7A20592B

But, I want to apply it per interface not globally on the switch. How do I apply the policy to specific interfaces (ports)?

[e.ciollaro]

I think that 3650 allow to configure the service-policy under an interf:

Switch# configure terminal
Switch(config)# interface gigabitEthernet...
Switch(config-if)# service-policy output <policy-map>
