wHILE BOOTING 7206VXR router , we get the message as follows :

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 600 bandwidth points.

This configuration is within the PCI bus capacity and is supported.

What exactly does this mean ?

rgds,

Hi Aman,

The 7200 has two buses used for the transfer of data between port adapters. Each of the bus has a limited capacity, which means that you can only install certain types of port adapters on each bus. The left bus includes slots 0 (i/o controller port),2,4,6 and the right bus includes slots 1,3,5.

Each type of port adapter consumes a certain number of points. You have to make sure that the total points consumed by the port adapters on each bus do not exceed 600.

In your case, you seem to have most of the port adapters in slots 2,4,6 which have used up 600 points. Therefore, you don't have a problem.

The following document has more info on bandwidth points:

Hope that helps - pls rate the post if it does.

Hi,

There are two PCI buses - left and right and slot are mapped to those buses evenly, and each bus having the maximum bandwidth capablity of 600 pts.

If you want further claification, just go thro,

sir,

Is there any command from where I can found how much bandwidth is being used by installed PA ?

Aman

[balajitvk]

Hi,

I don't think any command is there to provide you individual bandwidth point values. But you can get total bandwidth point value for each pci by issuing

show version command.

But u can calculate BWP values for each Portadapter u installed.

Pls. go thro. this site where BWP for each PA is given,

http://www.cisco.com/en/US/products/hw/modules/ps2033/products_configuration_guide_chapter09186a008014cf5c.html#wp1054013

By adding individual values, you can ensure the vaule u get in show version.

Hope this will help,

Sir,

I have tried to run show version command in two cisco 7206 VXR routers .

Both have them given as diffrent output .

Why is it so? Pls confirm ...

From the links given above, you will find that some port adapters have 0 bandwidth points. It seems the ones you have installed in the 7200 with the show version given above, that they have zero bandwidth point. This is like the 8 port channelised E1 adapter.

The different IOS should be responsible for the different formats of the show version, though the same information.

[pkhatri]

As indicated in that last point, some PAs do indeed have 0 points. One way to find out is for you to post the output of 'sh diag' from both of your routers. Then we can advise on why you are seeing what you are seeing.

Paresh

[amansoi_5]

Sir,

Please find enclosed Diag & version of both router s X & Y.

regds,

aman

[balajitvk]

hi aman,

From your show diag o/p, there are two types of PA your using.

One is V.35 and another is PA-MC-8TE1.

Both having BWP of Zero. That is why your show version is showing 0 BWP for both of your routers.

As u adding new PAs just go thro. the link that i sent you, by which u can calculate the BWPs.

Hope this will help,

Balaji.

[amansoi_5]

Just one more query :

suppose if I insert SA-VAM2+ , in either of slots i.e. in left or right bus , then I can't insert any other PA which which has bandwidth points other than zero.

I am left with only option of inserting PA( which consume BWP more than zero ) in bus other than where SA-VAM2+ is not inserted .

Confirm on this..

regds,

aman

[balajitvk · Accepted solution]

Hi,

Yes, Since SA-VAM2+ consume 600 BPW, you are left with the option of adding PA of BPW of zero on that remaining slots in that bus.

Otherwise it will raise the error msg like,

%C7200-3-PACONFIG:Exceeds 600 bandwidth points for slots 0, 1, 3 & 5

Rate if it helps,

Rgs,

Balaji. V

Sir,

Thanks a lot to Mr. Balaji & Mr. Paresh Khatri for such a long discussion.

Lot of effort has been put by both of you to resolve issue.
