Policy-map input on an interface VLAN

Hi there,
I have a problem with a policy-map on an interface VLAN on my Cisco 6509-E.
The switch has the IOS Version 12.2(33)SXI10, RELEASE SOFTWARE (fc2).
I have configured this policy-map:
policy-map PM-10Mbit
class class-default
   police cir 10000000 bc 1875000 be 3750000    conform-action transmit     exceed-action drop     violate-action drop
I bind this map on a physical interface
interface GigabitEthernet2/2
description <removed>
ip vrf forwarding <removed>
ip address <removed>
ip access-group <removed> out
service-policy input PM-10Mbit
service-policy output PM-10Mbit
and get this result:
show policy-map interface

Service-policy input: PM-10Mbit
    class-map: class-default (match-any)
      Match: any
      police :

Is this a bug or am I doing something wrong here?

Hello
As I understand it , this is command is required in mls qos because on a SVI ( L3 vlan interface) runs in a vlan-based mode which differs from normal L3 routed interfaces which run in interface mode.
As per cisco ="In VLAN-based mode, the policy map that is attached to the Layer 2 interface is ignored, and QoS is driven by the policy map that is attached to the corresponding VLAN interface."
Lastly regards
Try matching on all traffic incoming on the trunk interface on that switch for it to successfully police incoming traffic:
class-map V102
match input-interface x/x
Policy-map POLICE
class V102
Police xxxx xxxx

Policy-map based rate-limiting per vlan

Hi
I was thinking if someone could help me to come up with solution to a problem. Scenario as follow:
I have a trunk interface with multiple vlans on:
interface GigabitEthernet2/0/3
description TRUNK-to-*********
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 415,416,610,1191-1193,1195
switchport mode trunk
duplex full
storm-control broadcast level pps 1k
storm-control multicast level pps 3k
storm-control unicast level pps 250k
storm-control action trap
spanning-tree portfast trunk
spanning-tree bpdufilter enable
I'm trying to rate limit two of the vlans that are present on this trunk interface - vlan 415 and vlan 1192.
So I'm putting the class-map (to be later applied under the policy-map which is not significant here):
(config)#class-map match-any 120-mbps-class
(config-cmap)#match input-interface vlan 415
(config-cmap)#match input-interface vlan 1192
Now, when you show the class-map I created, I can see this:
sh class-map 120-mbps-class
Class Map match-any 120-mbps-class (id 1)
   Match input-interface Vlan415
   Match input-interface FastEthernet0
For some bizzare reason class-map is matching the Fa0. I have researched this, and this is most probably because you can only match 1 vlan instance under the class-map.
And here's my problem - I can't police whole interface as the other vlans should not be policed - how can I police those two vlans ?
Any thoughts ? All help appreciated as always.
Rob.

Hi Daniel,
I have labed it and unfortuantely it does not work as expected. I have put 1x 3750 and 1x 2960 trunk between them, each box had an access port for laptop to create some traffic across. All vlan-based qos has been applied on 3750G.
3750G config
Interface g1/0/20

2960 config:
interface g0/20

switchport access vlan 100
interface vlan 100
ip address 192.168.100.253
interface vlan 120
ip address 10.10.10.2
So as you can see vlan 100 is the one it need to be rate limited (I have only rate limited to 100kbps just to see if it's working) and vlan 120 is only on the trunk ports to confirm if the traffic for this one is not affected.
Unfortunately when the policing is applied on 3750 vlan 100 (and policing is working fine) then I can see the packet loss while pinging between switches on vlan 120 suggesting that the policy is affecting the other vlan as well. When I take the policy out of the vlan 100 I cannot observe the packet loss on vlan 120 meaning is no longer affected.
Not sure if I have explained this clear enough so far, if not let me know.
Do you have any suggestions ?
Thanks!

ACE - Policy map bound to multiple interface

Hello,
I have a policy map bound to multiple VLAN interfaces. The policy is pretty standard, any traffic hitting the VIP is load balanced.
Now, is it ok to assign the same policy map / VIP to to multiple VLAN interfaces on a virtual context?
I addition, I should add that one of the clients hitting the vip are the servers configured in the serverfarm of the context.
Basically the requirement here is that the rservers are client and server at the same time.
The problem I have is that when one of the servers send an HTTP request to the VIP, the ACE module reset the connection. I can see the dropped conns counter increasing as i generate requests to the ACE.
Rdgs,
Thibault.

Thibault,
the RESET is probably comming from the server.
If the server sends a SYN to the VIP, the packet is nated and forwarded to another server which sees a packet coming from a neighbor server (not ACE) and sends the SYN/ACK directly to the client(rserver).
This one is expecting a packet from the VIP and not the server itself and sends a RST.
You need to enable client nat for server opening connections to the vip.

Policy-map on tunnel or physical interface?

Hi all,
I have a 3800 headend router which has a number of ipsec tunnels to remote office sites. Our current QoS design applies a policy-map to each tunnel interface to prioritise and shape outbound traffic.
My question is how does the physical egress interface queue and transmit traffic from tunnel interfaces with this design? For example, if a mixture of large data packets and voice packets from different tunnel interfaces hit the physical interface around the same time what will happen to the voice packets?
Furthermore, would it be a better to apply the policy-map to the physical interface instead of the tunnel interfaces? What advantages if any would this bring?
Many thanks.

If you're shaping each tunnel to the outbound physical bandwidth, yes it would be better to just have the policy, without any shaping, on the physical interface. Again, you'll will either need to depend on a copied ToS value in the outbound packet or use qos pre-classify. (A single physical policy would be much like your QUEUE_DATA if using qos pre-classify.)
e.g.
!assumes qos-preclassify
interface Ethernet0
service-policy output QUEUE_DATA
What I thought you might be doing, and you could also do, was shape each tunnel to the far side's ingress bandwidth. This would require a distinct policy, if the shaper values change, for every tunnel interface, or a policy on the physical interface that has a class per tunnel (matches against tunnel destination address).
e.g.
!assume local outbound interface not oversubscribed
policy-map NESTED_QOS_512K
class class-default
shape average 512000
service-policy QUEUE_DATA
policy-map NESTED_QOS_768K
class class-default
shape average 768000
service-policy QUEUE_DATA
policy-map NESTED_QOS_1500K
class class-default
shape average 1500000
service-policy QUEUE_DATA
interface Tunnel1
service-policy output NESTED_QOS_786K
interface Tunnel2
service-policy output NESTED_QOS_512K
interface Tunnel3
service-policy output NESTED_QOS_1500K
interface Tunnel4
service-policy output NESTED_QOS_512K
e.g.
!assume local outbound interface not oversubscribed
class-map match-all Tunnel1
match group (ACL that matches tunnel1 destination address)
class-map match-all Tunnel2
match group (ACL that matches tunnel2 destination address)
policy-map outbound_tunnels
class Tunnel1
shape average 768000
service-policy output QUEUE_DATA
class Tunnel2
shape average 512000
service-policy output QUEUE_DATA
Interface Ethernet 0
service-policy outbound outbound_tunnels
If all the far side bandwidths exceed your local outbound physical bandwidth, then you should have both tunnel policies, that shape each tunnel, and a physical interface policy.
e.g.
!assume local outbound interface is oversubscribed
policy-map NESTED_QOS_512K
class class-default
shape average 512000
service-policy QUEUE_DATA
policy-map NESTED_QOS_768K
class class-default
shape average 768000
service-policy QUEUE_DATA
policy-map NESTED_QOS_1500K
class class-default
shape average 1500000
service-policy QUEUE_DATA
interface Tunnel1
service-policy output NESTED_QOS_786K
interface Tunnel2
service-policy output NESTED_QOS_512K
interface Tunnel3
service-policy output NESTED_QOS_1500K
interface Tunnel4
service-policy output NESTED_QOS_512K
!assumes qos-preclassify
interface Ethernet0
service-policy output QUEUE_DATA

Can you add one L3-class to two different policy maps ?

Hi Experts;
                Requirement is to have requests from outside as well as inside from different vlan Server to our Production Servers.At present all requests are coming from inside vlan via policy-map multi-match L3_XYZ. See Example below
policy-map multi-match L3_XYZ
class L3_PROD
   loadbalance vip inservice
   loadbalance policy L7_PROD
   loadbalance vip icmp-reply active
policy-map multi-match L3_OUTSIDE
class L3_PROD
   loadbalance vip inservice
   loadbalance policy L7_PROD
   loadbalance vip icmp-reply active
Many thanks
Regards

Hi Hidayat
yes, class map alone doesn't have any deep meaning and can be reused in many policy maps. Actually policy maps can be reused too, so in your particular example you can put the same policy map on 2 different interfaces. (Sometimes it's a good idea, if requirements are the same for traffic coming from both interfaces or if requirements are diffrent - it's better to create a new one, but class-map definitely can be reused.)

Policy map rules

I read that "Only one policy map can be applied to a specific interface". What if you alreay using the default policy map and want to create one for you AIP-SSM and one for the current ACL?

The default policy map is the "global" policy-map. If you want to send the traffic on all interfaces, through the SSM module, you dont need to create a new policy-map, you only need to create the class mathing the traffic you need to send via SSM module. Then you can include this class also in the policy-map applied globally.
With above said, assuming you have default policy-map config, if I implement following commands to divert all traffic via SSM module:
access-list ips-acl permit ip any any
class-map ips-class
match access-list ips-acl
policy-map global_policy
class ips-class
ips inline fail-open
Thus final policy-map configuration would look like:
policy-map global_policy
class inspection_default
inspect h323 h225
inspect h323 ras
inspect rsh
inspect rtsp
inspect esmtp
inspect sqlnet
inspect skinny
inspect sunrpc
class ips-class
ips inline fail-open
service-policy global_policy global
Alternatively, I cann apply the ips class to altogether a new policy-map but I cant apply this policy-map globally. I can apply the new policy-map to a particular interface though.
Hope that helps.

Vibhor.

1 policy-map for more than 1 physical interface

Hi,
the situation I want to achieve is, that 2 physical interfaces (here 2 TP GigbitEthernet Ports of a 3750) are limited together from one 'service-policy'/'policy-map'.
In the example below I have 2 Ports on one switch and the traffic coming in on both ports in total (traffic port #1 + traffic port #2) should be limited to the 'policy-map 5MBits'.
Right now I have configured a 3750 with:
class-map match-all EveryMAC
match access-group name everythingL2
policy-map 5MBits
class EveryMAC
police 5000000 32768 exceed-action drop
policy-map TEST
class EveryMAC
set dscp default
mac access-list extended everythingL2
permit any any
interface GigabitEthernet1/0/1
description port #1
switchport access vlan 123
switchport mode access
speed 10
duplex auto
interface GigabitEthernet1/0/2
description port #2
switchport access vlan 123
switchport mode access
speed 10
duplex auto
interface Vlan123
service-policy input TEST
And at the 'other side' a 2950 works with the following config:
class-map match-all EveryMAC
match access-group name everythingL2
policy-map 5MBits
class EveryMAC
police 5000000 32768 exceed-action drop
mac access-list extended everythingL2
permit any any
interface FastEthernet0/1
description port #A
switchport access vlan 123
switchport mode access
speed 10
duplex auto
As far as I can see this seems to work. But it would be nice if someone can confirm this or provide an other suggestion.
thanks in advance
Mark

Only thing i can think of is instead of using a MAC ACL , u cud jus use the default class
Policy Map Test
class class-default
police 56000 8000 exceed-action drop
Class Map match-any class-default (id 0)
Match any
You would be saving a MAC-ACL ;-).

Policy maps on port-channel sub-interfaces

We're trying to implement an enterprise QoS policy and I'm wondering how we can apply our QoS policy maps to several different sub-interfaces on a port-channel. In our case, we have both LAN and WAN connections that connect as VLANs on a switch and terminate as sub-interfaces on a port-channel that combines two Gigabit Ethernet interfaces on our router. The LAN connection will need to have a ingress service-policy to classify traffic as it comes from a customer LAN, and the WAN connections will have to have an egress service-policy to place the traffic classes into LLQ and CBWFQ queues as it leaves the router. Could I put both the ingress and egress service-policies on the physical router interface, or should I put them on the port-channel interface? Or should I apply them to the individual sub-interfaces? For example, I could put the ingress classification service-policy on the LAN sub-interface connection.
Any thoughts or insight would be helpful. Thanks.

I can't put it as input because :
gw-a(config-subif)#service-policy input policy_upload
Traffic Shaping feature not supported in input policy.
Here's a show during a bandwidth test. You can see the offered rate is properly measured and is _way_ above the target shape rate.

Best practice for web servers behind a router (NAT, ACL, policy-map, VLAN)

Hi,
I'm a new Network admin, and I have some configuration questions about my installation (see attachment).
I have 3 web servers behind a router.
Public interface: 3 public ip adresses
Private interface: router on a stick config ( 3 sub-interfaces, 3 different networks, 3 VLAN)
I would to know the best way to redirect http traffic to the right server.
My idea is to map a public address to a private address, via NAT, but I'm not sure for the configuration. I could also redirect via Policy-map and filter by url content.
So if you have some advise for this case, it would be really appreciated.
Thank you.
Chris.

Hello Christophe,
As I understand you want 1st that ;
if somebody go to A.local.com from internet then he will redirect to 192.168.1.10 in your internal network.
That means, you need static mapping between your public @ip address and your local ip address.
for this example, your local interface is Fa0/0.1 and I dont your public interface because it is not mention in your diagram. I will suppose S0/0 for public interface.
that is the config for the Web Server1. You can do the same with the remaining servers:
interface fa0/0.1
ip nat inside
interface serial0/0
ip nat outside
ip nat inside source static 192.168.1.10 172.1.2.3
static mapping from local to public.
I suppose you have done the dns mapping in your network and the ISP have done the same in his network.
ip route 171.1.2.3 interface serial0/0
or
ip route 0.0.0.0 0.0.0.0 interface serial0/0.
After these step for each web server, you will get the mapping.
Now you can restrict access to this ip only to http or https protocol on your isp and after on your local network
like
ip access-list extended ACL_WebServer1
permit ip any 192.168.1.10 eq www
deny ip any 192.168.1.10
exit
interface fa0/0.1
ip acess-group ACL_WebServer1 in
no shut
exit
That is the first step.
Second step : you want to filter traffic by url, that means layer 5 to 7 filtering.
I am not sure that it is possible using cisco router with (ZBF + Regex).
Check the first step and let us know !
Please rate and mark as correct if it is the case.

Show policy-map interface | Question about QOS show command output

I hope this is the correct place for this question. If not, please let me know.
When I issue the show policy-map interface command (in this case on a 3845) there is some output I don't understand. I have included some output below and formatted the lines I am confused about as "computer code" which show up as red on my screen. A list of the individual lines i'm confused about is below, followed by those liens in the context of the show policy-map command's output.
Any help with this will be greatly appreciated. Thanks in advance.

CBWFQ: Question about the output of "show policy-map interface" command

Hi everyone,
I have a question about the output of "show policy-map interface" command.
The following is the output of this command and lower side of the output shows
(total queued/total drops/no-buffer drops) 0/342/0
If the packets drop occur due to the situation of no enough buffer,
"no-buffer drops" counted up. But "no-buffer drops" has not been counted up.
The "no-buffer drops" is 0 (zero) but "total drops" are counted as 342.
I guess there are other factors except "no-buffer drops" to add "total drops".
But I can not find any information about "other factors".
So I would like to know the "other factors" added to "total drops".

Policy-map on catalyst 3550

dear all,
how to configure policy-map on catalyst 3550 to shapping bandwidth. I've tried to setting that police-map in one of interface, but when I wrote sh policy-map interface fa0/1, in class-map field, the result are
class-map: policeIn (match-all)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
match: access-group 112qm_police_inform_feature: CLASS_SHOW
Could u give me a clue..??
thx.

hi,
i've checked statistic of interface and there is traffic on that interface :
Hardware is Fast Ethernet, address is xxxx.xxxx.xxxx.xxxx(bia xxxx.xxxx.xxxx)
MTU 1500 bytes, BW 512 Kbit, DLY 100 usec,
reliability 255/255, txload 102/255, rxload 42/255

is there another way to shapping bandwidth per vlan or per port interface on catalyst 3550 with IOS 12.1(8).
thx.

ACE: 4710 Policy-Map NAT

Greets. I have a scenario where the rservers are located on two different VLAN's in One Arm Mode.
My question is, am I able to assign two different NAT commands in my policy map (as written below)? Will the NAT command only kick off for the selected rservers vlan?
policy-map multi-match PM_Loadbalance
class VIP_Farm
    loadbalance vip inservice
    loadbalance vip icmp-reply active
    nat dynamic 7 vlan 7
    nat dynamic 741 vlan 741
Thanks,
-b

Hello Brian-
You can apply 2 different NAT statements, yes.
The way it works:
1.) A client sends a SYN into a vlan where the vip is applied as a service-policy input.
2.) The ACE matches the SYN to the class in question, the loadbalance policy is checked, and eventually a server in the associated serverfarm is chosen.
3.) ACE prepares to forward the SYN out of the appropriate VLAN based on the route table.
4.) Before the packet leaves, if the packet will egress either vlan 7 or 741, the the packet would be source NATted by the group number mentioned in the statement. This occurs because the "vlan 7" and "vlan 741" in the NAT statements under the class are filters. If the destination matches either vlan, then the nat group for that statement is used.
i.e.
rserver host server_1
ip address 10.0.0.10
inservice
rserver host server_2
ip address 172.16.35.60
inservice
serverfarm host SF_1
rserver server_1
inservice
class-map match-any VIP_80
2 match virtual-address 172.16.35.80 tcp eq 80
policy map type loadbalance first-match LB
class class-default
serverfarm SF_1
policy map multi-match X
class VIP_80
loadbalance policy LB
loadbalance vip inservice
nat dynamic 5 vlan 7
nat dynamic 7 vlan 741
interface vlan 7
ip address 172.16.35.2 255.255.255.0
nat 5 172.16.35.100 172.16.35.100 netmask 255.255.255.0 pat
service-policy input X
Interface vlan 741
ip address 10.0.0.2 255.255.255.0
nat 7 10.0.0.100 10.0.0.100 netmask 255.255.255.0 pat
service-policy input X
If a packet comes into either vlan destine to 172.16.35.80 on port 80, it will be balanced to either 10.0.0.10 or 172.16.35.60. If 10.0.0.10 was chosen, then natpool 7 under vlan 741 would be used because 10.0.0.10 is layer 2 adjacent to vlan 741. If 172.16.35.60 was chosen, then natpool 5 would be chosen because that server is layer 2 adjacent to vlan 7.
