(11:18) Allen : Edit subnet ownership or modify route <https://internal.softlayer.com/NetworkSubnet/editSubnet/580798&gt;
(11:19) Allen : https://internal.softlayer.com/NetworkSubnet/editSubnet/580798
(11:20) Brent: okay
(11:21) Allen : yeah if they’re behind the same router, you go to the subnet page and then can just reroute it behind a different one
(11:22) Brent : how did you get to https://internal.softlayer.com/NetworkSubnet/viewSubnet/580798

modifiy VLAN

Hey a heads up on 23730901 when you do a VLAN change make sure you do a Null Network then Production to make sure ihas the new configuration. Had to do that to fix the issue on that one
(3:55:12 PM) brwyatt@jabber.softlayer.local/71fa98c: thanks I forgot that step. Will remeber next time

you can do a verify network to check the config. And prodcution network pushes the switch.
