Memory usage on VIP2-50 when I apply dTS

I when I apply service-policy on the PVC,

it seems that consumes about 600K at each

one. So I need to upgrade the VIP2-50, but

I don't know if I need to upgrade the SRAM

and DRAM, I just managed to see in "sh contro-

llers vip 6 sh-tech" the free total memory

decreasing, but I don't know if it is related

to SRAM ou DRAM.

Thanks,

Cleber

Re: Memory usage on VIP2-50 when I apply dTS

SRAM is used for Packet storage and DRAM is used for Processing. and former is fixed. If at all you can upgrade you can upgrade only the DRAM.

Thanks for your answer.

No, I can upgrade SRAM, you can see on this link below.

I've done a test, when I apply QoS (service-policy) at one PVC, it consumes about 600 K from DRAM, but I am wondering how I can calculate the SRAM

consumes.

In my opinion, adding more PVCs should have minimal or nil impact on the SRAM as it is used mainly to transport data as and when it arrives.

I'll use CEF dist (I think that it just consumes DRAM), but I am trying to find some way to estimate if I need or not to upgrade SRAM based the number of interfaces on VIP and its traffic. Certainly, if I have bigger traffic, my SRAM can start decreasing.

Thanks,
