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 ... View more

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? ... View more

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. ... View more

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. ... View more
