Juniper SSG-140 Slow Traffic

Posted on 2011-02-16
Last Modified: 2012-05-11
I have narrowed it down on our Juniper SSG-140  we have 3 Zones

DMZ-0/9  10/100/1000
Trusted -0/8  10/100/1000
Untrusted-0/2  10/100

Any time I copy a fle FROM the DMZ (DMZ->Trusted)  its very slow like 150-250 KB
Any time I copy a file FROM the Trusted (Trusted->DMZ) is fine and fast like 30 - 50MB

I have look through all my polices and find no traffic shaping policies to hender this, and have not engres and egress set at all on the DMZ or the Trusted interface

the only thing that looks out of shorts is  the Interfaces Page Reads out the Ethernet0/9 - DMZ as 100mb and it should be 1000mb  and the Ethernet0/8 - Trusted is reading out as 1000mb like it should

FYI those too ports are suppose to be 10/100/1000 ports and all the rest are 10/100

There seems to be a switch or a hub in between DMZ to Trust that is dropping it down to 100

You may need to manually set the interface bandwidth and duplex from the command line. That should sort out the issues with transfer speed

I know we have the 100mb 1000mb issue a while ago on both those ports, and I we had to change duplex setting on the ports, all the switch connected up to these 2 ports are Cisco 2960 Gigbit switches..

I 'm not to versed in the commands on this FW so I don't know what the syntex is for manaully setting the bandwidth?

For 1GB full duplex (which doesn't make much sense, since GB runs best with auto-negotiation):
    set interface eth0/9 phy full 1000mb

how would you set it to auto then?

set interface eth0/9 phy auto

this should do it. when you are using the command line. If you partially type a command, you can use the 'tab' key to fill in the rest of the command or the '?' key to show the available options.

set interface eth0/9 phy ?

will display:
device-> set interface trust phy
auto                 auto negotiation
full                 force full duplex
half                 force half duplex
holddown             holddown time

device-> set interface trust phy
