Script to change the management subnet mask on HP switches

Question

This might not be the right place to ask this question since it revolves around HP switch command line syntax, however..

I'm trying to write a config snippet that changes the management subnet mask on a group of HP2524 switches. So far i've got

config
vlan "Default_vlan"
ip address ipaddress new_subnet_mask
exit
exit
exit
y

My problem is that the 'ip address' command needs an IP address (this is the switch management address) which is a static, hence diferent for each of the switches. I can't cahgne them all to DHCP : we have a standard of static address for our switch management.

Thanks

Andrew

(I hadn't realised you could do that : embaressment)

I ran the script as you suggested and got the following result:

config
vlan "Default_vlan"
ip address 192.168.203.30 255.255.252.0

The good news is that the script is picking up the correct IP address but seem to be failing to applying the new subnet. (I'm pingng this test switch before, during and after the script runs. If the script is successfull then the ping would fail as the subnet mask changes, as happens when I do this manually. And I'm deliberately not writing the config change to NVRAM so I can just reboot the switch to recover if the script does work.)

Can you try right-clicking on one of the HP switches and selecting Execute Script and running you script?    This will allow you to see the results of that command running on your HP device.   Please paste the results into your post and we'll continue to troubleshoot.

Chris,

Thanks for the speedy reply. The node variable looks like what I want.

I tried this:

config
vlan "Default_vlan"
ip address ${AgentIP} 255.255.252.0
exit
exit
exit
y

..and got a completed upload with the follownig result info:

terminal width 0
terminal length 0
config terminal
config
vlan "Default_vlan"
ip address ${AgentIP} 255.255.252.0
exit
exit
exit
y
end

Unfortunately the subnet mask remained unchanged
