Problem connecting with Cisco 3400

Hello,

We have recently upgraded our net connection to a 10 meg Ethernet circuit delivered over fiber.  The Telco has installed a Cisco 3400 Switch onsite that we have set as the gateway and configured it as they would for any other client.  We are unable to get the full 10 megs in both directions and I need some assistance.

The standard configuration for the Telco's switch is 10FDX, so I've locked my interface on the ASL at the same rate.  I am connecting to an FTP server that is on the Telco's network 1 hop away for testing.

Uploading to the site I get a full 10 megs, downloading I see between 10-100KB, or under a megabit of performance.

We've tried having the telco change the port configuration to 100FDX and auto, and in turn matching the config on the ASL, yet this seems to reverse the problem.  With this 100 meg or auto setting I can download at 10 megs, yet my upload starts crawling.  The telco also shows errors on the Cisco port when we try this configration.

I will be working more with the Telco tonight to attempt to resolve this issue, if anyone has any experience with Cisco's interfacing with ASL's and specific settings that we could try on the Cisco or on the 220 I'd appreciate the input.

Side note to this, when we plug a laptop into the same port on the Cisco we get much better bi-directional performance.  We have also swapped out the Cisco, the cabling and the ASL unit (I have 2 in HA) to no avail.

Thanks in advance for any suggestions!

I've had problems with our HP running ASL, and a Cisco switch, after an inline IPS was put in between.

The solution was to lock everything at 100/full.

ethtool on the command line will tell you how the NICs are currently configured.

Thanks for the quick response, we did try locking everything at 100 full, yet per my post this caused errors in the other direction, showing massive amounts of input errors on the Cisco interface.  It gave me the ability to download at the full 10 megs, yet my upload became the slow point.  I am currently configured as follows:

        Supported ports: [ TP MII ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
        Advertised auto-negotiation: No
        Speed: 10Mb/s
        Duplex: Full
        Port: MII
        PHYAD: 1
        Transceiver: internal
        Auto-negotiation: off
        Supports Wake-on: g
        Wake-on: g
        Current message level: 0x00000007 (7)
        Link detected: yes

And the ISP's switch is hard set to 10 full, when I checked the interface last night at 100 full it showed exactly what I would expect.  Is there a tool included in the ASL build to allow for me to monitor the ports for errors as I could in the Cisco IOS? (live monitoring with the option to reset)

Thanks again,

Keith

One additional note, we don't show errors on the Cisco or the ASL when it's set to 10 full, we only show the performance loss. We show errors on both sides when we lock them both at 100 full.
