I think this is very basic for someone who has some ecperience with Cisco Firewalls.

I have a Cisco PIX515 and I want to set both it's "inside" and "outside" ethernet interfaces to 100 HALF duplex. I have all the passwords. What commands should I use?

On the switches I used to manage I did this:

config t

int fastethernet 0/1

speed 100

duplex half

<CTRL-Z>

write mem

done.

With the 515 PIX I can't get that far. I enter the config mode:

config t

then I see, by using "show int" that both the ethernet0 and ethernet1 interfaces are set to 100 full duplex. What should I do? "speed" and "duplex" commands are not available.

Thank you in advance...

Try;

interface ethernet0 100basetx—Set

show interface

Nothing.

Help says the command format is

interface <hardware_id> [<hw_speed> [<shutdown>]]

<hardware_id> is "ethernet0", since I dont' get any error up to that point.
<hw_speed> is not "100" since that gets not accepted. I don't know where the DUPLEX setting would fit.

This help?

Looks like it should be:

interface ethernet0 100basetx

<shrug>

LOL.

"100basetx—Set for 100 Mbps Ethernet half duplex communication"

The version of that page that I found when checking my facts had "100basetx--Set for 100 Mbps Ethernet half duplex communication".

Cut and paste errors are always fun.

Thanks. I'll give it a try tomorrow morning...

interface ethernet0 100basetx

Worked out great.

Thank you guys!

Noooo problem.
