To reset a brocade switch back to the factory default

configDefault

Now that the switch is default, set a new IP address

Switch:admin> ipAddrShow

Ethernet IP Address: 10.77.77.77
Ethernet Subnetmask: 255.0.0.0
Gateway Address: 10.77.77.1

Once I checked the existing settings, I ran the ipAddrSet command to update the network settings:

Switch:admin> ipAddrSet

Ethernet IP Address [10.192.40.148]: 10.10.104.13
Ethernet Subnetmask [255.255.240.0]: 255.255.248.0
Gateway Address [10.192.40.254]: 10.10.104.1
