ATM 8500 Traffic Resources adjustment

[richard.turian]

I`ve created ctt rows as a traffic resources for ubr pvc circuits. I was able to creat certain number of pvc circuit until the system rejects adding another new pvc`s (%connection creation fails: specified traffic/resource parameters are invalid). After cisco ducumentation it is bandwidth allocation issue. How can i adjust maximum available bandwidth for VP tunnel? What`s the command for this adjustment?

Hi,

The way to allocate bandwidth to VP tunnels is to specify an appropriate rx and tx CTTR when configuring it:

atm pvp vpi rx-cttr tx-cttr

The VCs using this tunnel will then be restricted to an aggregate bandwidth as specified above.

To help you better, it might be useful to see some of your config ...

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

Ok, here is a part of config & sh atm int resources

Hello,

You can use the command 'atm cac overbooking 1000' under your ATM interfaces which will allow for 1000% overbooking on your PVCs.

Alternatively, you can configure your UBR CTTRs without the 'mcr' specified. For example, instead of:

atm connection-traffic-table-row index 40 ubr pcr 52000 mcr 52000

use:

atm connection-traffic-table-row index 40 ubr pcr 52000

Either of the above should do the trick.

Hope that helps.

Pls remember to rate posts.
