Screen OS

how do I check the interface speed and duplex on a netscreen 208 firewall

Thanks

CLI: get interface <interface>

for example: get int e1

Thanks. ok, so if the int is down.. I will not be able to see the speed and duplex correct?

Also, how to set to 100 full?

Hi,

I would try "get config | inc ethernetX" (x = interface number).  This should show you what is in the configuration.  See example below.  You can also use "get int eX".  This will show the current status (i.e. link up, phy-link up/full-duplex).  If you need to change the setting, you can use "set int eX phy full 100".

NS-500-C-NS-500(M)-> get config | inc ethernet1/1
set interface ethernet1/1 phy full 100mb

I hope this helps.

Thanks this helps a lot.

the issue is the device connected to the fw keeps defulting to half duplex but the firwall is set to 100full. When they hard code to 100 full their int shutsdown..

So if we both set our int to 100 / auto they default to 100/full.

Is there any downfall to having the int set to 100/auto if it defaults to 100/full?

thanks

Interface negotiation is always fun 🙂

If you have one sided hard coded (100 Full) and the other side auto  - you get what you saw - 100 half. You are best off running both sides hard coded or both sides auto  - whichever works best with the two devices. No real downfall to either. I like hard coding but if it causes a shutdown then auto works just fine.

Ok great. They are both set to auto and they both show 100/full.

Im going to leave it.

Thanks for everyones help.
