Catalyst 3560C QoS

[iagomeiri]

Hi experts,

Do the 3560C (compact) catalyst switches have any limitation compared to common 3560 ones in regards to QoS configuration/support/features?

Is there any guide for configuring QoS specific for this series or the one for common 3560 is valid?

Thanks very much!

Hi Iagomeiri

They support auto qos like any 3560 but no mls qos like some standard 3560s also support but you only need one type do marking correctly so auto will work fine on compact , no restrictions compared to full platform

this doc is for 3560s too you will see the heading

Hi Mark,

Sorry but still not very clear to me.

What I want to do in the 3560C is to mark (change DSCP) the inbound packets of different interfaces and VLANs based on source/destination IPs and/or destination protocol and/or port number and have the granularity to apply this either per interface (as a whole) or per VLAN. Using MQC with access-lists, class-map,  policy-map. And then applying with the service-policy to the interface/vlan. Would this be possible on the 3560C?

Something similar to this:

ip access-list ext al_ssh
 permit tcp any host 10.200.200.5 eq 22
ip access-list ext al_telnet
 permit tcp any any eq telnet

class-map cm_ssh
 match access-group name al_ssh
class-map cm_telnet
 match access-group name al_telnet

policy-map pm_mark
 class cm_ssh
  set dscp cs5
 class cm_telnet
  set dscp af41
 class class-default
  set dscp cs1

int f0/1
 switchport access vlan 999
 switchport voice vlan 700
 mls qos trust device cisco-phone
 service-policy input pm_mark

Thanks very much!

Hi Iagomeiri,

You can achieve the remarking you want in the 3560-C, please refer to the 3560 configuration guide (Applies for 3560-C as stated in the Overview), Configuring QoS Chapter in the following link:

http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3560/software/release/15-0_1_se/configuration/guide/scg3560/swqos.html

For 15.0 Releases you can achieve the ingress marking with MQC using access-groups as you need.

Hope it helps,
