Hello hii

I have 1Gbps connection and I given 1gbps input on Cisco 2911 router but I can't get output speed from 2911 router .It's get around 250 to 300 Mbps download and 50 to 60 upload speed. I had done following configuration on 2911 router.

 

interface GigabitEthernet0/0

 
 ip address *.*.*.* Subnet address
 ip nat inside

 ip virtual-reassembly in

 duplex auto

 speed auto

interface GigabitEthernet0/1

 description  1gbps

Cisco recommends the 2911 for up to 35 Mbps WAN bandwidth.

Cisco has also documented the 2911 can pass up to 114 Mbps, @75% CPU, for IMIX traffic while doing NAT/PAT.

It's possible you're bumping up against the performance limits of your 2911.

What's the CPU usage when you max out?

BTW, considering your much lower "up" bandwidth performance, what kind of gig circuit is this?

check model performance maximum, i am afraid you can go 1GB as expected.
