Bandwidth point on Cisco 7206VXR (NPE-G2)

After greeting...
PCI bus mb1 (Slots 1, 3 and 5) has a capacity of 600 bandwidth points.
Current configuration on bus mb1 has a total of 0 bandwidth points. 
This configuration is within the PCI bus capacity and is supported. 
PCI bus mb2 (Slots 2, 4 and 6) has a capacity of 600 bandwidth points.
Current configuration on bus mb2 has a total of 800 bandwidth points.
is there any effect on router when bandwidth points exceeded it's point like i marked above???if there is please point it to me...

Hello Sami,
Trust you are doing great.
When installing cards into a 7200, there are clear guidelines as to the order in which slots should be used, in order to maximize the available backplane bandwidth. The bandwidth is divided between two pci buses that are used to connect left and right hand cards. The available bandwidth is split between the left and right slots on the chassis. Cisco uses a system of bandwidth points, whereby the different types of interface cards have a bandwidth points value. For instance a PA-A3-OC3 card has a value of 300 points. On a 7206VXR router, the total bandwidth points for the either the left or right-hand side slots must not total more than 600 points. The bandwidth points should be evenly distributed between the left and right slots
Now from the logs which you have shared, it seems that you have installed Port Adapters on left half whose Bandwidth point sum is exceeding the 600 Bandwidth Point limit for the left side.
Effect of this:  The effect would be that the Port Adapters you have used in Left side may be working in "Half Bandwidth Point".
This would allow to use only one interface out of two in the Port Adapters.
When there is any oversubscription, below message is also displayed in "show version"
The set of PA-2FE, PA-POS-2OC3, and I/O-2FE qualify for "half
bandwidth points" consideration, when full bandwidth point counting
results in oversubscription, under the condition that only one of the
two ports is used. With this adjustment, current configuration on bus
mb1 has a total of 600 bandwidth points
 Please let me know if there is any concerns about these.
Regards,
Mohit

    Hello
    its not very clear why you want to upgrade and what features you need to support.  You seem to be running T train image which generally has a number of new features., and I believe 12.4 is now rather old. Perhaps you should look at 15.2 and check feature navigator and release notes to see if it has all the features you need.
    i believe it is good practise to use the correct boot image too to match your chosen ios.
    hope this helps

  • PPPoE Cisco 7206VXR + NPE-400

    Hi ,
    i am wondering if 7206VXR + npe400  is good enough for terminating (as BRAS) 2000 pppoe sessions over ethernet.
    What is max number of pppoe sessions on such hardware ?
    Is it possible to make traffic shaping for each separate pppoe session ?

    Hi,
    Here is the  link for the PPPOE session limit, which might be helpful:

  • Oversubscripted Bandwidth Points on 7206VXR

    Hi,
    I just want to ask about bandwidth points on cisco 7206VXR with NPE-G1.
    What will happen if bandwidth points oversubscripted on one of the PCI bus?
    This is the sample:
    ===========
    PCI bus mb1 (Slots 1, 3 and 5) has a capacity of 600 bandwidth points.
    Current configuration on bus mb1 has a total of 0 bandwidth points.
    This configuration is within the PCI bus capacity and is supported.
    PCI bus mb2 (Slots 2, 4 and 6) has a capacity of 600 bandwidth points.
    Current configuration on bus mb2 has a total of 640 bandwidth points.
    The set of PA-2FE, PA-POS-2OC3, and I/O-2FE qualify for "half bandwidth points" consideration, when full bandwidth point counting results in oversubscription, under the condition that only one of the two ports is used. With this adjustment, current configuration on bus mb2 has a total of 340 bandwidth points.
    This configuration is within the PCI bus capacity and is supported under the above condition.
    ==========
    What happen when 2 ports of PA-POS-2OC3 activated?
    Thx
    Iwan

    72xx PAs are hot-swappable. What we've done in similar situations is to schedule a maintenance window, copy the configuration to a text editor and search/replace the affected interface numbers, add a "no shutdown" on the config to the physical interface to which the card is going.
    Console in. At the scheduled hour yank, shove, paste the config. Your customers on the affected card should be back up in less than two minutes.
    Not really relevant to this specific issue but it is generally a good idea to have a specific maintenance window at specified off hours for singly-homed customers (and even multiply-homed just in case). 2:00 AM Sunday morning local time as an example. Situations like the above, upgrading IOS for security fixes or features, etc. will always come up from time to time. If it's expected it usually isn't a big deal and they often appreciate the attention to keeping your network up to date.
    Back to your original question, things will still work in an oversubscribed state unless you're pushing near full wire speed in which case you'll start to get packet loss. If you need to open a TAC case or get support you'll be told not to do it, and perhaps to fix the issue before getting further support.
    This document:
    http://www.cisco.com/en/US/products/hw/routers/ps341/products_tech_note09186a00800c814a.shtml
    says "You can use a 7200 series router with a PA configuration that exceeds the guidelines that the Cisco 7200 Series Port Adapter Installation Requirements provide. However, in order to prevent the occurrence of anomalies while the router is in use, restrict the type of PA that is installed in the router in accordance with the guidelines. Additionally, in order to have Cisco Technical Support troubleshoot these anomalies, your PA configuration must be within the guidelines."
    which may give you the ammunition you need.

  • Nice People HELP ME!!! IPv6 over PPPoE Configuration on Cisco 7206VXR

    I have a 7206VXR which connects to a DSLAM via the router's ATM/DS3 interface. A CPE home router connects to the DSLAM. So it's like:
    PC -----ethernet---- CPE Router ------ dsl line ------ DSLAM ----- atm/pppoe ------- BVI/Virtual-Template/PPPoE on Cisco 7206VXR
    Now the problem is:
    - PC CAN ping the BVI interface of Cisco, but NOT beyond that. For instance he can't ping 7206's loopback ipv6 address.
    - I found something interesting on the CPE, that CPE itself can't ping BVI interface of Cisco, AND it doesn't have a default gateway ::/0 set on itself. I manually added a default router like "route -A inet6 add ::/0 gw <BVI's IPv6 addr>", and the problem got solved and PC can ping Cisco's loop back IP now. But this is not a solution since I want this thing to be automatically ready.
    Note both CPE and PC are happy with global IPv6 addressed assigned.
    I believe this problem is related to how PPPoE/IPCPv6 handles addresses and prefixes.
    Ok, now some configuration details: I use 2001:7:7::/64 for the "WAN" side of CPE, and 2001:8:8::/64 for its LAN side (PCs). And here's the Cisco config (only related stuff is shown here):

  • New Entry Point in Cisco Interaction Manager

    I have created a new Entry Point in Cisco Interaction Manager for web chat. I used a new Queue and a new Script for the que script selector. I added a new ICM queue script for the chat, a new Dialed Number / Script Selector. When I test the new chat, the entry point works and shows the new entry point name in the CIM agent, but it still queues to the existing queue in ICM, not the new one. Anyone have any idea what I might have missed?
    Thanks - Keith                  

    Hey Lara, the emails are not getting queued because they are abnormally handled after success path of Queue to skill group.
    please add a wait node, after success path of queue to skill group. set time in wait node to max time you want emails to stay in queue. may be after this you can use another queue or send some label back to CIM, which matches to non IPTA group on CIM.
    the same is applicable for Chat as well.
    coming to the point at the subsequent chat not routing to the same agent, this one depends on max concurrent task you configure in CIM for Chat queue.
    there is config tab in each ICM integrated queue called "Concurrent task limit", this is the one deciding factor on how many concurrent task for each queue an agent can handle.
    please try and let me know if that works.
    regards
    Chintan

  • QoS on Cisco 7206VXR DMVPN

    Hello,
    one of my customers wants to implement VoIP in his existing DMVPN Network Topology. I have read about the "Per-Tunnel QoS for DMVPN" but when it comes to configure it on my hub router (Cisco 7206VXR with c7200p-advsecurityk9-mz.124-15.T14.bin) I am lacking the option to set the "ip nhrp map group" command.
    My question now is, is it generally not supported by the 7206VXR platform? Or can I get the option by upgrading the IOS to a newer version? If so, which one could I use ?
    Kind regards

  • 7206VXR NPE-G2 IOS 15.1(3)2 netflow problem

    Hello,
    I am trying to configure netflow on 7206VXR NPE-G2 and IOS 15.1(3)2. Put ip flow ingress on interfaces, but cache is empty. Rollback to 12.2(33)SRE3 and netflow is working good (I see traffic in cache flow). Any idea?

    Ops, sorry IOS 15.1(3)S2.

  • Bandwidth Point value for the Escon Adapter Card PA-4C-E

    In the document "Cisco 7200 Series Port Adapter Hardware Configuration Guidelines" I didn't find the Bandwidth value for the PA-4C-E ?
    The only value mentionned on that document is for the Adapter PA-1C-E. Which is 100 for this adapter.
    Can somebody tel me if the Bandwidth value is equal for both adapters.
    Thanks a lot........Regards/Michel

    Hi Michael,
    I'm looking at the online version of the document you refer to, http://www.cisco.com/univercd/cc/td/doc/product/core/7206/port_adp/3471pac6.htm
    , which only mentions the PA-1C-E. First, yes, the value is the same for the newer adapter, the PA-4C-E. Second, I'll start the process of getting the documentation updated. Thanks for pointing out the problem.
    Rgds, Dan

  • Creating a 20MB bandwidth using two cisco asa 5515x with a hub (10/100/1000)

    hi all,
    I would like to simulate a bandwidth of 20MB for my DR project testing on my two cisco asa 5515x and with a cisco hub (10/100/1000).  I was thinking to make two connections on my "outside" vlan with both speed of 10 and etherchannel it and do it again on the other asa.
    Do you think it will simulate 20MB bandwidth?  Or any other suggestion?  Please add any comment, thanks to all.

    Hi Nicholas,
    You have the HSRP running between your core devices. You can have your core A - ASA1 & Core-B - ASA2.
    In your core switch you need to have a sepearate VLAN to connect the uplink to the firewall and asusual in asa you can have the primary and standby address configured and in core also you can have the vlan with hsrp ip configured.
    But make sure that in your firewall you should mention the static routes for each subnets pointing to the core device hsrp.
    The other scenario is you have make you ASA a standalone firewalls and in one firewall you need to have route to core a as primary and core b as secondary and in the other firewall vice versa. So that your traffic will get load balanced.
