CSR 1000v bandwidth very slow

[mohammed hashim]

hi,

I am using CSR 1000v in my environment and noticed those machines which linked to int gig 2 communicate very slow with machines linked to gig 1,

like if I copy a file, speed is about 300kb

configuration is minimal, only ip addresses are configured with ip routing enabled on the router.

how to troubleshoot it ?

thanks,

First thing I would do is

show interface g1

show interface g2

and verify how it negotiating speed/duplex. 

Verify if there are any errors on the interface. 

Speed/duplex mismatch is a common trouble.  Best practice is auto on both sides.

Bare minimum,  interface Gig need to match speed/duplex settings on device on other end of link. 

Auto <-> Auto or

hard coded <->  hard coded

Hope this helps,

if so, please rate.

What license have you got installed?

I recall reading something about the demo license only allowing around 2Mbit/s of throughput, which is close to what you are seeing.

I've noticed this as well. I have a VM lab running on my laptop host (Linux Mint). I have the guests running in KVM. If I use a Cisco CSR as the router, my web GUI connections to an A10 and Netscaler are SLOOOW. But if I use a VyOS router, they're lightning fast.
