As I understand it, CC-link IE networks are not routable (still hoping that someone proves me wrong). Does anyone have an idea, documents, URLs or live experience with large scale CC-link IE designs? I would like to integrate a CC-link IE environment into a IP-based environment and look for documentation that explains how this integration an be done. If someone has Wireshark traces of such an environment this would be helpful as well.

Thanks to both of you! I was not aware of the Aero IE. I will have a close look into it.

Does anyone know an App that would show me the name of thee AP I am connected to? All Apps I know only show me the BSSID, the name would be so much easier in large deployments that use a meaningful names.

Has anybody been able to get ERSPAN running on NCS 540 with XR6.3? I am trying to look at traffic coming in from a TenGig interface and I am getting:
Tue Nov 27 16:42:14.827 UTC !! SEMANTIC ERRORS: This configuration was rejected by !! the system due to semantic errors. The individual !! errors with each failed configuration command can be !! found below. interface TenGigE0/0/0/4 monitor-session fiji ethernet direction rx-only !!% 'SPAN' detected the 'warning' condition 'The platform encountered an error processing a SPAN operation': Operation not supported ! ! end
What is the most likely reason for this, except for that the feature will be available in the next release?

Hi
Are there any plans to have MPLS encapsulation on pseudowires on ISR C1100 routers (AC on L2 interface)? If so with what release can that be expected?
Kind regards
Mat

Are there any performance studies on QoS in ASR9K high speed interfaces? I would like to mark based on QoS groups (MPLS EXP) but I wonder about the impact of such a configuration. Has anybody tested scenarios like that?

Cool idea, however it seems to be hardware related:
router(config)#int g0
router(config-if)#band 266666
router(config-if)#service-policy output PM-TEST
Configured Percent results in CIR out of range. Allowed CIR range is 1000-154400000.
The present CIR value is 266666000

As I said before the max-reserved-bandwidth command has been deprecated since IOS 15.0 or 15.1. So no possibility to use that one. The fair-queue is a good hint, I'm sure that I had it in a previous version, I have to check why I removed it.
Kind regards

Hi
As I said in an answer before the policy-map works fine with lower bandwidths. It's the shaper that seems to cause the issue. I have set up a policy-map with only a shaper and get the same error:
policy-map PM-TEST class class-default shape average percent 100
interface GigabitEthernet0 bandwidth 200000 service-policy output PM-TEST
-> Configured Percent results in CIR out of range. Allowed CIR range is 1000-154400000. The present CIR value is 200000000
The actual CIR value and the allowed CIR range look like 100%/75%. So that's why I think it might have something in common with the 75% rule ( max-reserved-bandwidth). But I have not found any documentation that gives me details on my situation.

Hi
the error only pops up when I try to apply the policy-map to a Gig Interface with a configured BW of 200000 kbps. The policy map as such works perfectly for scenarios with lower bandwidths.
Here's the config including the class-maps:
class-map match-any CM-NET-CONTROL description matches Routing Protocols, BFD and LDP match dscp cs6 match mpls experimental topmost 6 match qos-group 6 class-map match-any CM-QG5 match qos-group 5 class-map match-any CM-QG3 match qos-group 3 class-map match-any CM-QG1 match qos-group 1 ! policy-map PM-L2-OUT description LEVEL2 Out Policy class CM-NET-CONTROL bandwidth percent 20 set mpls experimental topmost 6 ! class CM-QG3 bandwidth percent 20 set mpls experimental topmost 3 ! class CM-QG1 bandwidth percent 50 set mpls experimental topmost 1 ! class class-default random-detect queue-limit 300 ms set mpls experimental topmost 0 ! policy-map PM-CORE-L1-OUT description LEVEL1 Out Policy class CM-QG5 priority level 2 police rate percent 10 ! set mpls experimental topmost 5 ! class class-default service-policy PM-L2-OUT shape average percent 100 ! ! interface GigabitEthernet0 bandwidth 200000 service-policy output PM-CORE-L1-OUT

Hi Georg
I basically match to QoS-groups (QG...) that were set on the input interfaces with matching of PHBs. But that does not really add valuable information to the question I have. I asked for the shaper, not for the marker. And to keep the output short I omitted the class-maps.
Kind regards
Mat

Hi I'm trying to apply the following QoS config:
policy-map PM-L2-OUT description LEVEL2 Out Policy class CM-NET-CONTROL bandwidth percent 20 set mpls experimental topmost 6 ! class CM-QG3 bandwidth percent 20 set mpls experimental topmost 3 ! class CM-QG1 bandwidth percent 50 set mpls experimental topmost 1 ! class class-default random-detect queue-limit 300 ms set mpls experimental topmost 0 ! policy-map PM-CORE-L1-OUT description LEVEL1 Out Policy class CM-QG5 priority level 2 police rate percent 10 ! set mpls experimental topmost 5 ! class class-default service-policy PM-L2-OUT shape average percent 100 ! interface GigabitEthernet0 bandwidth 200000
When I try to apply the service policy to Gig0 the router complains:
router1(config-if)#service-policy output PM-CORE-L1-OUT Configured Percent results in CIR out of range. Allowed CIR range is 1000-154400000. The present CIR value is 200000000
It looks a bit like the max-reserved-bandwith thing, however that does not exist anymore in IOS 15.3. I tried it with real bandwith values in the policy-map, no success either. Is there a numeric upper limit for a shaper, is this box dependent, or is there another possibility to get this running? I have not found any clear explanation or even better a solution to my problem.

I can see the General Membership Query on a regular basis of 60 secs and the two Group-specific queries 1 sec after the other. It is IGMPv2 I am looking at.
So, yes the wireshark capture time is greater then the igmp query interval.

What triggers a L2-switch configured as "ip icmp snooping querier" to send out group-specific queries to a multicast group? I know that this normally happens after IGMP Leave messages to speed up the Leave process, however in my case there are no such messages visible in a wireshark trace. I wonder whether there are other conditions that bring the switch to send out this kind of message.
Any hint is appreciated.
