[c-nsp] 3750ME QoS

[Swaroop Potdar]

Egress policing on 3750 is not supported, you can do only Egress shaping.
 
Ok so coming back to the problem on hand, can you try this config, 
and update about the results.
 
3750(config)# access-list 103 permit <vlan2-4 Source> <vlan302destinations> dscp 1
3750(config)# class-map class1
3750(config-cmap)# match access-group 103
3750(config-cmap)# end

3750(config)# policy-map CUST
3750(config-pmap)# class class1
3750(config-pmap-c)# trust dscp
3750(config-pmap-c)# police 48000 8000 exceed-action drop
3750(config-pmap-c)# exit
3750(config-pmap)# exit
 
3750(config)#interface vlan302
3750(config-if)#service-policy input CUST
 
HTH-Cheers,
Swaroop

	Hello!
	
	Here is my 3750-Metro config example:
	
	mls qos
	interface FastEthernet1/0/6
	 description Customer
	 switchport trunk encapsulation dot1q
	 switchport trunk allowed vlan 302,303,304,305
	 switchport mode trunk
	 mls qos vlan-based
	
	interface GigabitEthernet1/1/1
	 description MAN
	 switchport trunk encapsulation dot1q
	 switchport trunk allowed vlan 2,3,4,303,304,305
	 switchport mode trunk
	
	interface Vlan2
	 ip address 192.168.0.1 255.255.255.252
	
	interface Vlan3
	 ip address 192.168.0.5 255.255.255.252
	
	interface Vlan4
	 ip address 192.168.0.9 255.255.255.252
	
	interface Vlan302
	 ip address 10.0.0.1 255.255.255.252
	
	ip route 10.0.1.0 255.255.255.0 10.0.0.2
	
	
	Vlans 2-4 are members of OSPF driven IP MAN with many routes
	in it.
	
	
	I need to do rate-limiting for all traffic arrived via any vlans 2-4
	with some dscp value and routed to customer's Vlan302. Something
	like this:
	
	class-map match-all DSCP1
	  match ip dscp 1
	policy-map MAN-TO-CUSTOMER
	  class DSCP1
	    police 1000000 8000 exceed-action drop
	
	interface Vlan302
	 service-policy output MAN-TO-CUSTOMER
	
	
	
	And limit all traffic received from customer's Vlan302 that forwarded
	to vlan 3 only, but untouch traffic from other vlans
	
	class-map match-all CUSTOMER1
	  match input-interface Vlan302
	policy-map CUSTOMER-TO-MAN
	  class CUSTOMER1
	    police 1000000 8000 exceed-action drop
	
	interface Vlan3
	  service-policy output CUSTOMER-TO-MAN
	
	
	Both examples are invalid for 3750-Metro hardware.
	
	Is there any other way to do such things?
	
	Thanks!
	
	P.S. IOS 12.2(25)SEG, but up|down-grade is not a problem
