Frequent VPN link Bounce & tx/rx rates are low

[pwynne2009]

Hi.

I have an ASA5510 talking to a Cisco 800 Series router with Bootstrap version 12.3 providing a site to site VPN. I am seeing intermittent drops in the connection and the transfer rates are very low.

87MB's is transfering at between 80 & 90K per second.

The 5510 has a 100M internet pipe and the 800 series router connects to a contended 8MB line. (ADSL)

What transfer rates should i be seeing and if there any way of fine tuning this connection?

Paul.

Hi Paul,

Which direction are you experiencing the slow transfer on?

From the 5510 -> 800 or the other way around?

Are there any errors or collisions seen on the outside interface of the 800 due to speed/duplex mismatch?

Thanks,

Rob

Hi,

I am testing from the 800 to the 5510 and to another 5505 in another site. Mesh topology in use here.

I have checked the interfaces and there are no collisions or duplex mismatches.

A test from both locations shows me taking almost 35mins to copy a 70MB folder from each of the other sites.

Its really strange. Both ASA's are up to the latest rev's in software.

• Ping times from the 800 to the 5510 are between 50-60ms
• Ping times from the 800 to the 5505 are between70-90ms.

The internet connection here will be upgraded in the next couple of weeks so the 800 series router will have a 20mb internet connection. the upload speed is pretty low, around 1-2mb but download should hit 15mb max, its an ADSL delivery platform.

Rgds,

Paul.
