4/16 SAN sw - no network connection

Hello All,

 

we have an old (configured 3-4 years ago) 4/16 switch (os ver. 3.5).

i try to check config, but i didn't know the ip addresses, so i used a

serial cable and a terminal.

I changed ip (it was the default: 10.77.77.77) with ipaddrset, then

I checked the config with ipaddrshow, everything seems to be good,

but there is no network connection! i tried to ping, telnet, web, I checked

port 22, 23, 80, 443 but nothing. I tried via switch or directly pluged

the cat5 to my notebook.

I checked ipfilter with "ipfilter –-show", it said every port are permitted...

I didn't tried to reboot or switchDisable and switchEnable, because

this switch still working... I think reboot not necessary for changing an ip address...

 

Any idea?

 

thanks / regards
Andras

Re: 4/16 SAN sw - no network connection

Andras, if I recall correctly, once you change the IP of a switch, you need to reboot it for it to take effect.  Quickest way to verify this is to ping the new address that you have assigned to it and then if that does not work, ping the 10.77.77.77 address.  I am thinking you will find that it still replies to 10.77.77.77 and not the new address, until you rebot the switch.

ipaddrshow in FOS 6.3 does not mention that you have to reboot the switch. Maybe it was different in yours. Are you on 3.5 or 5.3 or what?
Did you run ifmodeshow/ifmodeset too? If not, do check them out.

Thanks for getting back! Glad you got it working agian.

Maybe, this is a 'feature' in FOS 5.3?
