Brocade Silkworm 2800 - network Connection

[Dave Thomson]

Morning.

I changed my brocade switch from a 10mbs network connection to a 100mbs connection. I now can no longer see the switch from the lan.

I have changed it back - still will not connect to lan. All network configurations have been checked 5 times and changed to different configurations - still no joy. Network support has confirmed the link is working - i have verified this.

It seems as though the brocade switch needs a reboot. I can not afford to do this as it will affect production.

Is thier any other way i can reset the network connector on the brocade ?

Thanks

Welcome to the club :-(

Is the interface set to 'Auto-negotiate'? I would try and temporarily set it to something other and the back via the front panel - good luck!

Hey Dave,

First of all, let me confirm you that you don't need to reboot the switch to get the ethernet port's mode change config in effect.

It will be helpful if you can tell us more how you changed the settings and how you revert back.

Have you tried pinging the ipaddress? If yes then you may try to connect through the serial port to the switch and see if any telnet session is there. If any, kill it. If still doesn't help, run configure (without switchdisable), it will allow you to disable the telnet on the switch and then enable it again.

If it still doesn't work, call Brocade engineer to resolve the problem.

You can go through the admin. serial port via the com port on your laptop. After you logged into the switch do a ifmodeshow and then a ifmodeset "feiX" (X ismost likely 0-look at ifmodeshow).

> ifmodeshow
fei (unit number 0):
Link mode: 100 Mbps / Full Duplex
lo (unit number 0):
Link mode: Not applicable

> ifmodeset "fei0"
100 Mbps / Full Duplex (yes, y, no, n): yes
100 Mbps / Half Duplex (yes, y, no, n): [no]

-It will then prompt you for speed and duplex mode. Answer yes to one and then no to the rest.

I've had this happen to me hundred times with these older silkworm switches. Good Luck

Hello

Thanks for the replys. Im going to try and connect a labtop, serial connection.

I have done all the configuration changes via the lcd screen on the brocade.

Mabey it is not updating properly.

I spoke to the supplier and they recommend a re-boot of the switch...

Ill try the serial link first.

Cheers

My experience with certain Cisco switches have been that:

If I boot the Brocade/server first, it will not talk to the Cisco.
If I boot the Cisco switch first, and then boot my system/Brocade - it will talk.

Basically the Cisco switch is real touchy.

These are the same switches that after crashing one afternoon, they will not talk to the servers/brocades that stayed up throughout the network switch re-boot process. I had to re-boot several servers in order to talk to the network switch again.


I can connect a laptop with a crossover cable all day and get a good connection from the brocade. So, I know that it is the Network switch that is the touchy one!
