Switch IP address

[Madsen, Andrew]

Is there a standard IP address used for the message passing switch in an Evolocity cluster. The first switch I can get to just fine but I cannot seem to find an IP address for the second. All the IP addresses in that vlan are 192.168.250.x but I have not been able to stumble across it from the compute nodes.

Often, switches and similar devices were kept on their own subnet and only available off the main host. You could look at the hosts file there; however, I'm assuming you've tried all that and there is no entry for it. You could try creating a virtual interface off the host (ifconfig eth0:1 192.168.0.250) and do a broadcast ping (ping -b 192.168.0.0 or ping 192.168.0.255 - this differs per the distro) to see if the switch responds. Also, you should be able to hook up a serial cable (may need an rj11->db9 adapter) and find out that way. My hunch is that the IP would be 192.168.1.something or .2.something, but that's the best I can suggest.

I looked through the documentation for this order and couldn't find a
record of IP addresses, it was a long shot anyway. I have to agree
with Cameron, at this point your best bet is a broadcast ping, and
then resorting to hooking up the serial cable. There's a chance that
an IP address wasn't even set on this switch.

Another option is to reboot the switch.
If it has not been configured, it should try to get an IP address via
dhcp
just make sure the dhcp server is listening on the interface the
switch is connected to

Hope this helps

Thanks all. The broadcast ping revealed the bad boy. It is funny the
first switch's last octet was 201 and I tried that on and then 200 and
when it did not hit on a ping I started at 100 and started up before
trying the broadcast ping (frankly I had forgotten using that shame on
me) and the switch responded on 202 I had stopped too soon.
