Class-map in IOS XR

Hi, anyone can explain the "sh class-map list type qos" in XR platforms ? is this command used to know how many types of class-maps configured in one router ?

It is a useful command to help clean up unused class-maps:
RP/0/RSP0/CPU0:A9K-BNG#show class-map list type qos
Thu Sep 12 14:58:56.383 EDT
1) ClassMap: class1    Type: qos
    Referenced by 3 Policymaps
2) ClassMap: class3    Type: qos
    Referenced by 2 Policymaps
in this examples the QOS class-maps class1 and class3 which have index 1 and 2 respectively are used by respectively 3 or 2 policy-maps. can't remove them.
I could technically remove this class-map:
20) ClassMap: v6    Type: qos
    Referenced by 0 Policymaps
Not used at all.
regards
xander

IPv6 class-map or IOS problem

Hello, sorry because of my bad English at first,
I have a problem with my IPv6 ACL, IPv6 Class-map or IOS I'm not sure so I'm asking you.
I have one 1721 router with one Ethernet and one FastEthernet interface, on Fa interface is 3 subinterfaces, and Eth interface is connected to 10 Mbps link to another 1721 router. I'm working on QoS for VoIPv6. My softphone emulator address is FEC2::1/64.
This is my configuration:
class-map match-any v6
   match access-group name v6
policy-map v6
   class v6
    set ip dscp ef
ipv6 access-list v6 permit FEC2::/64 any
Question is, why is output of command show policy-map interface Fa0/0 showing that not a single one packet of IPv6 is not beeing marked:
R1#sho policy-map interface fa0
FastEthernet0
   Service-policy input: v6
     Class-map: v6 (match-any)
       0 packets, 0 bytes
       5 minute offered rate 0 bps, drop rate 0 bps
       Match: access-group name v6
         0 packets, 0 bytes
         5 minute rate 0 bps
       QoS Set
        ip dscp ef
           Packets marked 0
     Class-map: class-default (match-any)
       92 packets, 9134 bytes
       5 minute offered rate 0 bps, drop rate 0 bps
       Match: any
This exact configuration, with IPv4 is working fine. My IOS version is c1700-y-mz.122-11.T11.bin
If IOS version is too old, can you tell my what version will work so I can purchase it?
Thanks

If you are thinking of IPv6 prefix I tried everything. From /128 for single host to /64, nothing works.

Update List of Protocols When Configuring a Class-map During IOS FW Configuration

Hi Everyone.
I am working on a 2911 router with IOS version 15.2 and I want to configure Zone Base Firewalls. I have a list of protocols I want to allow through the firewall but when I do match protocol ? after creating a class-map of type inspect, I don't see some of the protocols like rtp, rtcp, secure-imap and skype. Is there anyway I can update the list of protocols available to be selected?
Thanks

You should be able to match on any of the applications in NBAR. Have you updated to NBAR2? It can be downloaded here-
http://software.cisco.com/download/release.html?mdfid=282774227&flowid=7440&softwareid=284509011&release=7.0.0&relind=AVAILABLE&rellifecycle=&reltype=latest
The release notes list all the protocol definitions.
Hope it helps

Policy map/ class map/ service policy for IOS xr

Hi,
I need to create a policy map and class map/service policy to limit the amount of bandwidth that can be used on one interface both in and out.
I need the cap for the bandwidth to traverse this circuit to ne 10 Meg.
the IOS xr version we are using is 4.3.4
I was hoping someone could help me out by giving me a configuration example I could follow.
Thank you.

for instance like this:
policy-map police-in
class class-default
police rate 10 mpbs <optionally set burst>
policy-map shape-out-parent
class class-default
shape 10 mpbs <optional burst config>
service-policy shape-out-child
policy-map shape-out-child
class class-default
queue-limit 10 packets
int g 0/0/0/0
service-policy police-in in
service-policy shape-out-parent out
also have a look at CL 2013/2014 (orlando/sanfran) ID 2904 for more QOS details
and the support forum article of "asr9000 quality of service architecture"

IOS Firewall: what is this class map doing?

Hi, a few weeks ago I set up a class map but now as I am finding time to review my config, I am wondering what effect this has. It is applied to a policy map for ssh access from the Internet to the router for management:
class-map type inspect match-any SSH
match protocol ssh
match access-group name SSH
The access list with the name "SSH" just allows certain public IP network blocks.
But I think I should be setting this to match-all and not match-any if I want it to allow the ssh protocol from only my IP, correct?
Also just to ensure I am not confused about proper creation of the ACL. The ACL with the name SSH I've given is as follows:
ip access-list extended SSH
permit tcp xx.xx.0.0 0.255.255.255 any eq 22
permit tcp xx.xx.0.0 0.7.255.255 any eq 22
permit tcp xx.xx.0.0 0.255.255.255 any eq 22
First, am I being redundant in the class map by telling it to match protocol ssh and also specifiying port 22 in the ACL? And, is this ACL readout done properly if I want only certain IP blocks to be able to come in from the Internet, to the router, using ssh?

Hello Colin,
But I think I should be setting this to match-all and not match-any if I want it to allow the ssh protocol from only my IP, correct?
Exactly you are getting it now It needs to be a match all....
Regarding the ACL should be like this:
access-list SSH
permit tcp host outside_user_ip host router_outside_interface eq 22
Regards,

Default class map is dropping all Packets

Hello I have a Cisco 871 router that used to have Access list based security. now I am trying the ZBFW for the first time. I thought I had a pretty good program until I found all my traffic was getting dropped. This is my first stab at ZBFWs and I am a bit confused esp with the default class part. Any help is greatly appreciated!!!!
The router is for my house and thus also has to have priority for gaming. I will add the gaming and voice QOS once I get it working,
Guest VLAN has access to 2 IP's in Data for printing.

Hello Charlie,
I would recomend you to investigate a little bit more about how the ZBFW features works
Now I am going to help you on this one at least, then I will give you a few links you could use to study
We are going to study traffic from MyNetNet-zone to the MyNetWan-zone
First the zone-pair
zone-pair security MyNetNet->MyNetWAN source MyNetNet-zone destination MyNetWAN-zone
service-policy type inspect MyNetNet-zone_to_MyNetWAN-zone_policy
so lets go policy-map
policy-map type inspect MyNetNet-zone_to_MyNetWAN-zone_policy
class type inspect MyNetNet-Class
inspect
class class-default
Finally to the class map
class-map type inspect match-all MyNetNet-Class
match class-map MyNetNet-access-list
match class-map Voice-protocols
match class-map Extended-protocols
match class-map Base-protocols
That keyword MATCH-ALL is the one causing the issues!!
Why?
Because you are telling the ZBFW to inspect traffic only if matches all of those class-maps so a packet will need to math the base protocols and the extended protocol and as you know that is not possible ( Just one protocol )
So here are the links

How to get OIDs of indexes for class-map ?

I have policy-map configured on cisco router with some class-maps inside. I need to draw a graph traffic passing through these classes. To make a graphs I use Cacti which use SNMP query to draw the graphs (object name cbQosObjectsIndex).
How to get OIDs of class-map indexes ?
I tried to do this by following query:
#snmpwalk -c community_string -v 2c 192.168.0.252 1.3.6.1.4.1.9.9.166.1.5.1.1.1
but the answer was:
iso.3.6.1.4.1.9.9.166.1.5.1.1.1 = No Such Object available on this agent at this OID
The information i need is contained at the OID 1.3.6.1.4.1.9.9.166.1.15.1.1.7:
# snmpwalk -c community_string -v 2c 192.168.0.252 1.3.6.1.4.1.9.9.166.1.15.1.1.7
iso.3.6.1.4.1.9.9.166.1.15.1.1.7.1251.1277 = Gauge32: 0
iso.3.6.1.4.1.9.9.166.1.15.1.1.7.1251.13363 = Gauge32: 0
iso.3.6.1.4.1.9.9.166.1.15.1.1.7.1251.13383 = Gauge32: 0
iso.3.6.1.4.1.9.9.166.1.15.1.1.7.1251.13435 = Gauge32: 734000
iso.3.6.1.4.1.9.9.166.1.15.1.1.7.1251.13481 = Gauge32: 233000

Because 192.168.0.252 1.3.6.1.4.1.9.9.166.1.5.1.1.1 is marked "non-accessible" according to http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=cbQosObjectsIndex
You'll need to obtain the indices as explained in this blog post:
http://pierky.wordpress.com/2009/04/09/cisco-class-based-qos-snmp-mib-and-statistics-monitor-for-nms/
Joe wrote a very illustrative post on the subject of snmptables: https://supportforums.cisco.com/message/3051004#3051004
And if your IOS supports it, you would want to configure the following to keep the indices from changing after every reboot or OIR:
"snmp mib persist cbqos"

Class-map does not support match protocol ssl

I have several 1941/k9's that do not have the class-map command: to suppot ssl. System image is c1900-universalk9-mz.SPA.152-1.T.bin.
class-map match-any af31
match protocol ssl <-- missing.
I did some google searches but come up with nothing.
Is the fix to upgrade IOS? I have found it on other routers running c1900-universalk9-mz.SPA.152-4.M4.bin. I would just upgrade and check but have an extensive change review board with questions before doing so.
Thanks for advice,
Haydn

I'm not current on NBAR (or NBAR 2), but NBAR used to support loadable modules (PDMs?). Sometimes Cisco would provide those so you could add match protocols without upgrading your IOS.
Otherwise the "fix" would be to upgrade your IOS.
Lastly, depending on what it matching SSL really means to you, using port based ACLs might suffice (in fact, some NBAR match protocol is only really that, but some NBAR matches regardless of the port usage).
PS:
Also on the subject of SSL, don't forget much can use it. I once matched on it for the purposes of providing secure shell higher queuing priority, worked great for SSH, not so great when secure copy (SCP) also matched against it.

QoS Class-maps

Trying to understand the class-default for marking
I have the concept of Identify traffic with ACLs
Classify traffic for marking with class-maps
Mark traffic with policy-maps
the policy-map will always have a default-class for unaccounted traffic in the policy-maps
what I don't quite understand is that the there is not a class-map class-default
when servicing the "policy" the class-maps are referenced with "class A" "class B" "class class-default"
when looking for the matches on class class-default there is no reference class-map to go to....
I figured I have to accept this logic means if traffic was not specifically matched by the collection of class-maps in the config the IOS can assume the traffic would have been/is class-default.
i had put a config together to classify certain traffic as CS0, like SNMP... i wanted to force traffic there as well as having all unaccounted traffic being classified CS0.
but from what i read if i don't have snmp matched in any class-map in the config then this traffic would find itself in
policy-map XXX
class class-default
set ip precedence 0
even though class-default does not exist as class-map class-default

Hi,
You want to mark some traffic as CS0? and then count that traffic? but you won't know which traffic had CS0 imposed or was natively IPP 0 like all data traffic not specifically marked.
the class class-default exists just do a show class-map and you'll see it, it is the IOS which creates it.
Doing a show policy-map interface will show you which class-map was matched.

3850 QoS class-map match-all?

I would like to create a QoS marking policy that re-marks packet to CS5 if the inbound traffic is SIP *and* if it is marked CS3 when it comes in. I would have expected the configuration listed below will work. I only found out when I tried to apply the config that, unlike other IOS devices, "class-map match-all" does not exist in 3850 3.3.x code. It can only do "class-map match-any" Can anyone suggest a work-around config for 3850 to achieve the same end result?
ip   access-list extended ACL-QOS-SIP
permit tcp any range 5060 5061 any
permit tcp any any range 5060 5061
ip   access-list extended ACL-QOS-CS3
permit ip any any dscp cs3
class-map   match-all CM-QOS-CS5
match access-group name ACL-QOS-CS3
match access-group name ACL-QOS-SIP
policy-map   PM-QOS-MARKING
class CM-QOS-CS5
     set ip dscp cs5
Any suggestions would be appreciated.

jlkeys, below is configuration I ended up using to resolve the issue:
ip access-list extended ACL-QOS-SIP
permit tcp any range 5060 5061 any dscp cs3
class-map match-any CM-QOS-CS5
match access-group name ACL-QOS-SIP
policy-map   PM-QOS-MARKING
class CM-QOS-CS5
   set ip dscp cs5

Class-map || High Router utilization

Hi Team ,
Good day!!!
I have one very basic question regarding the class- map.
We have implemented QOS by defining some set of classes with the percentage of bandwidth in each class.
now a days i could see lot of routers in the organization i work for having issues with the high utilization .
we heard that the ISP has changed their configuration of QOS.
is it like both the customer and ISP should have the same kind of configuration to have my router work properly ?
if one class is being highly utilized, will it affect the entire router performance ?
Thanks
Praveen

Hi parveen,
It's a common problem after implementing QOS, plz share the details of hardware and software.as well as At the beginning you can start your troubleshoot with these documents:

Number of class maps (QOS) supported on 7200 and 7600

Hi,
Have few queries on class maps for QOS, putting forward for your comments/inputs.
1. Want to know if there are any limitation (s) on the number of class maps (to be applied inbound/outbound) that can be configured on the 7200 and 7600 routers.
2. Is there any imitation on the numbers (of class maps) in general or will it depend on the sum total of BW configured in the classes? I mean which one will be the deciding factor i.e. if the limit is wrt to the configured classes or the number of classes can't go beyond the consolidated bandwidth configured on the interface.
Kindly share details on the same and if there are any recommendations.
Thanks! in advance.

"Q. How many classes does a Quality of Service (QoS) policy support?
A. In Cisco IOS versions earlier than 12.2 you could define a maximum of only 256 classes, and you could define up to 256 classes within each policy if the same classes are reused for different policies. If you have two policies, the total number of classes from both policies should not exceed 256. If a policy includes Class-Based Weighted Fair Queueing (CBWFQ) (meaning it contains a bandwidth [or priority] statement within any of the classes), the total number of classes supported is 64.
In Cisco IOS versions 12.2(12),12.2(12)T, and 12.2(12)S, this limitation of 256 global class-maps was changed, and it is now possible to configure up to 1024 global class-maps and to use 256 class-maps inside the same policy-map."

A problem with ACL in the class-map on the ACE module

Hi all,
I configured the following on the ACE module:
object-group network test
host 192.168.1.21
host 192.168.1.22
host 192.168.1.23
object-group service port
tcp eq www
tcp eq 8080
access-list T line 8 extended permit object-group port object-group test any
I tried to configure a class-map for matching this ACL:
ACE-4710-2/Lab-OPT-11(config)# class-map match-any TEST_C
ACE-4710-2/Lab-OPT-11(config-cmap)# match access-list T
Error: Cannot associate acl having object-group ACEs in class-map.
So couldn't I configure the class-map by using ACL with object-groups involved? Is it the bug or the normal behaviour? Because the customer uses object-groups in ACLs and he has to configure ACL without object-groups for the traffic classification. It is horrible.
Thank you
Roman

Hi Roman,
I'm afraid it's the expected behavior. You cannot use an ACL with object-groups inside a class-map.

Daniel

How can I install Google Maps on IOS 6?

Since I upgraded to IOS 6, Google Maps has been replaced by a poorer Apple version that doesn't support public transport. I want Google maps back. How can I install Google Maps on IOS 6 or downgrade to IOS 5?
Thanks.

Google Maps has not yet or does not look like they are creating a standalone app at this time.
It is not easy to downgrade, not recommended by Apple, very involved in order to do that. Again, not recommended.
Use MapQuest for now if you are unhappy with Apple Maps. I was never happy with Google Maps, so I have been using MapQuest for a long time for all directions.

Using Wildcards in HOST Class-Map

I want to use a wild card to match a HOST in a class-map. I want to match multiple hosts for the same site:
? Support.Cisco.com
? Employee.Cisco.com
? Helpdesk.Cisco.com
I want to match this with *.Cisco. Will this work?

You are right, my mistake
