ASR 9000 series PPP session limit

Hello!
Guys could you plese tell how many ppp sessions ASR 9000 can terminate.We are planning no build SP network I know 7600 series routers cаn terminate 64k ppp session per box ( 16K per ESP+ module 8K per SIP module).
Unfortunately I could not find any information regarding this matter anyware.
A believe A9K-SIP-700 module can do that.
Thanks a lot

Correct, when you are using a bundle, the resources are replicated and programmed on all NPU's that have members in that bundle.
So for instance, if you have a MOD80 linecard, and you have 2 members in a bundle, and each member is located on a different NPU, then you will be limited to 32k subs TOTAL on that linecard, because the first limit
There is a limitation of 32k subs per NPU.
is already met.
And well stated indeed! The disadvantage is that we burn the same structures on multiple NPU's, so duplication of programming maybe, but it does provide for Advtange of seamless failover between bundle members.
To continue on your design: if I'd have a 36x10 card, which 6 NPU's and 2 member bundles, I can easily reach 64k
even if the bundle members are spread over 2 NPU's.
I would need 2 linecards for this obviously.
With a MOD80, having 2 NPU's, and 2 member bundles whereby the members are connected to each NPU, I am limited to 32k subs on that LC because of the first limit, but if I have 4 linecards like this I can have 4x32k subs no problemo
because then we hit the system scale clause.
Not sure if this makes it more clear or whether I am confusing you more, but let me know if this makes it more complex
and I'll try again

    FAQ

    Is there a Cisco lab available for ASR 9000
    we have "XR4U" stations coming available soon when XR 511 comes alive. The plan is for a downloadable play image like that. In the interim we have 2 demo systems available, and they can be booked via your account manager representative.
    How will MOD160 perform with multiple 9000NVS?
    very well. the mod 160 has 4 NPU's, 2 per bay. So if you have a 4x10 MPA to serve a satellite, you effectively have a single NPU per 20 1Gigs from the satellite. The pps performance will be stellar. However it might be price technically more ideal to connect satellite with a 36x10. Since the MOD-x has native MPA's with 1G also.
         2. Is there a shortcut for a Bundle-EthernetX interface, such as port-channel interface (poX), in Cisco IOS® ?.
    usability enhancement is there, we are trying to push this into a new reasonable release. follow CSCuh04526
         3. What  is the revolutions per minute (RPM) on these hard disk drives (HDDs)  compared to the solid state drives (SDDs)? Will the spinning drives be  slow?
    depends on the type we had avaialble at time of production, you will see different sizes and disks on the RSP2. the rpm of the HD is not so much an issue as much as the buffered writing we used to do in XR. This is fixed up with XR43 where the disk writing performance is much better. the HD/SDD is used for logging storage only (and maybe your pictures) but other then that we're not that concerned with write perf of the HD.

  • How to configure snmp on loopback interface, on vrf TEST, in ASR 9000 series

    Hi there!
    How to configure snmp v2, with community string, for ASR 9000 series, in interface loopback 1, that has vrf TEST
    Regards!

    oh that is somewhat vague, but let me try...
    in order to enable snmp access to an interface in a vrf you need to enable MPP (management plane protection) in that vrf.
    Something like this:
    control-plane
     management-plane
      inband
       interface Loopback100
        allow all
    if you have this and it doesn't work, a config snippet and some debugs (like debug snmp packet) will help to define what to do next.

    Hi Andrew,
    This counter indicates:
    Number of times Outside-to-Inside packets (TCP + UDP + ICMP, Static + Dynamic) dropped because there is no NAT DB entry corresponding to the Destination IP and L4 Port.
    Please check your static route and ensure only the packets with destination address matching with public IP pool is sent to outside service app interface.
    Alternatively, some of those entries could be timed out as well so when the O2I packets reach, it does not find a NAT DB entry and gets dropped.
    You can refer the following guides as well to check out some other relevant commands (like, 'show .. outside-translations'):

  • Visio Stencil Request- Nexus 9000 Series

    Hello there,
     I attempted to download the Visio Stencils for the Nexus 9000, but inside was the stencils for the ASR 1000 series. Has anyone else seen this? When can we expect the stencils for the Nexus 9000 series?
    Thanks in advance!

    Hi,
    Sorry for not responding more quickly. Unfortunately, I don't know of any reason why this .vss would not open in OmniGraffle since it was produced using the same techniques in our standard production process. The file is saved in Visio 2002 "or later" format for maximum compatibility with Visio. The Omni Group is responsible for the conversion from Visio to OmniGraffle formats so they would be the ones to question about this. Our mission is to support Visio users and our operations are Windows based so we do not test the stencils on Macs although we do our best to produce files that can be used in OmniGraffle.

  • Is there any session limit in operator?

    Hi,
    I am trying to run a loop thru a query, like " select col1 from table1", then in this loop I am trying to call a scenario, like : OdiStartScen -SCEN_NAME=TESTEXTRACT -LOG_LEVEL=5 -SYNC_MODE=1 "-project.var1=#col" , the query should return about 7000 rows, that means the scenario should run for about 7000 times, but the fact is in operator is only run about 60 times, and no new session produced, and the main loop is hanging there?
    Is there any session limit for the operator? or any other possible resovle method for this?
    Thanks

    Hi ,
    You can limit the number of session u can view in the Operator.
    In Operator--- > File --- > User parameters = In this you can see operator display limit. In tat you can set ....
    Hope this helps !

  • CLI session limit 32 reached. Exiting. on nexus n5k

    Hi Guys ,
    I'm having a problem with Nexus n5k , when i'm trying to telnet to the machine ,i get this error :
    "CLI session limit 32 reached. Exiting."
    I can connect to it by console ,but i don;t know how to clear all those sessions .
    Needs help
    Thanks ,
    Ron

    I am also having this issue on out 5Ks.  We resolved the problem before by consoling into the system and doing "show users" and then "clear line (vty-line)".  This will allow you to ssh or telnet into the system again.  But I am wondering how I can determine why this is happening all of a sudden.  I have been working with our Nexus 5K for over a year and a half and have never had this issue.  Now all of a sudden it has happend two time in the last 3 months.  What do I need to look into to resolve this?  I am not not exiting properly and it is not killing the session?  Please advise.

  • Exceeded session limit on CPU usage

    Hi All,
    We are getting message while generating some reports. Pl. see the Error Text below for message. For time being we have  bumped the session limit to unlimited to take care of this problem for now. But the question is u201CIs there a way available in MII to refresh(cycle) the Data source connectionu201D  So that the DB session limit can be kept un altered?
    When we search this on different forums, we got a solution which we aleady implemented(bumping the session limit to unlimited). But we are looking for a solution from MII side.
    Any help will be appreciated

  • ISE-5443 RADIUS request dropped due to reaching EAP sessions limit

    Hi Guys,
    I am getting the below error message from two PSNs (out of 4) & resulting 95% failed authentications on ISE
    "5443 RADIUS request dropped due to reaching EAP sessions limit"
    Could not find any documents/reference & trying to get on hold TAC in the mean time.
    If anyone of you know what could it be, pls share your inputs
    TIA
    Rasika

    Hi Scott,
    Thanks for that..
    here is bit more information about this evnts log in ISE system (1.2 Patch 4).
    Event: 5405 RADIUS Request dropped
    Failure Reason :5443 RADIUS request dropped due to reaching EAP sessions limit
    Resolution : Wait a few seconds before invoking another RADIUS request with new EAP  session. If system overload continues to occur, try restarting the ISE  Server
    Root cause: A RADIUS request was dropped due to reaching EAP sessions limit. This  condition can be caused by too many parallel EAP authentication  requests.
    Worked with TAC & restarted the service of one PSN node & that brings that node to normal condition & removed the other PSN form the F5 pool until TAC analyze gathered support bundle from that.
    It is not heavily loaded environment (3k wireless clients) at the moment & bit scary since we are expecting around 15k when students are back in early March. Authentication failure rate is around 100 in every 15-20s interval. Not sure what is the limitation of the ISE system itself to handle number of EAP sessions per second.

  • ASR 9000 route-policy on ipv4 and vpnv4 neighbors

    Hi
    To reduce configuraton i would like to use the same route-policy for ipv4 and vpnv4 routes from the same neighbors on ASR 9000.
    I know that a "pass all" route-policy will work just fine, also a route-policy like this works fine:
    route-policy eBGP_NEIGHBORS
        set local-preference 50
      endif
    end-policy
    But why doesn´t this route-policy work?
    rd-set EXT_SERVICES_PRIMARY
      1.1.1.1:*
    end-set
    rd-set EXT_SERVICES_SECUNDARY
      2.2.2.2:*
    end-set
    route-policy eBGP_NEIGHBORS
      if rd in EXT_SERVICES_PRIMARY then
        set local-preference 120
      elseif rd in EXT_SERVICES_SECUNDARY then
        set local-preference 20
      else
        set local-preference 80
      endif
    end-policy
    The effect of this is that vpnv4 routes looks just fine but ipv4 routes is missing in bgp table. I have tryed all kind of configs but it just will not work, what am i missing?
    The idea of this route-policy is that routes advertised by rd 1.1.1.1 will act as primary and rd 2.2.2.2 as secundary.
    1.1.1.1 and 2.2.2.2 is handleing the same routes.
    1.1.1.1 is located in one AS and 2.2.2.2 in an other AS
    my ASR that i am working on is in a third AS
    And alla other routes will have a default local-pref of 80

    If you watch the if statement, you're challenging that if the RD is something, or else, else... but, maybe, it doesn't work if you don't have an RD.
    Based on the Mohit's answer I think that maybe, that's the reason.
    route-policy eBGP_NEIGHBORS
      if rd in EXT_SERVICES_PRIMARY then
        set local-preference 120
      elseif rd in EXT_SERVICES_SECUNDARY then
        set local-preference 20
      else   <<< So if not "EXT_SERVICES_PRIMARY" and not "EXT_SERVICES_SECUNDARY", but stills in "if rd.."
        set local-preference 80
      endif
    Mohit's:
    route-policy eBGP_NEIGHBORS
      if rd in EXT_SERVICES_PRIMARY then
        set local-preference 120
      elseif rd in EXT_SERVICES_SECUNDARY then
        set local-preference 20
      endif
        set local-preference 80 >>>> Outside the if statement!
      end-policy.
    Let us know if the Mohit's answer worked! Just to learn something new :)

Maybe you are looking for
