A new SW:

Rack mount it ,  power on the SW.Connect through serial port, default IP Add is 10.77.77.77./255.255.255.0 in case of Dir 10.77.77.74/75

with admin login:

Set the IPaddress(ipaddrshow/ipaddrset),

set the time with either NTP server IP(tsclockserver cmd) or tstimezone --interactive cmd

check the license(licenseshow)

add the license with licenseadd cmd

Atleast Full fabric / XX domain licenses to form ISLs.

Trunking licenses for trunking(trunks will be formed while connected through common speed, same quad/octet)

give a switch name(switchname XXX)

change the passwords and keep it in library

always ask one time password of root , while taking the new sw from any vendor and keep it in library for further troubleshooting

do a portstatsclear, portlogclear

disable the SW with switchdisable cmd

clear the configuration with cfgclear cmd

set the fabric.ops parameters through configure cmd(specially unique Domain ID(1-239), Pid format, data field size, )

fabric.domain:20
fabric.ididmode:0
fabric.ops.BBCredit:16
fabric.ops.E_D_TOV:5000
fabric.ops.R_A_TOV:10000
fabric.ops.bladeFault_on_hwErrlevel:0
fabric.ops.dataFieldSize:2048
fabric.ops.max_hops:7
fabric.ops.mode.fcpProbeDisable:0
fabric.ops.mode.isolate:0
fabric.ops.mode.longDistance:1
fabric.ops.mode.noClassF:0
fabric.ops.mode.pidFormat:1
fabric.ops.mode.tachyonCompat:0
fabric.ops.mode.unicastOnly:0
fabric.ops.mode.useCsCtl:0
fabric.ops.vc.class.2:2
fabric.ops.vc.class.3:3
fabric.ops.vc.config:0xc0
fabric.ops.vc.linkCtrl:0
fabric.ops.vc.multicast:7
fabric.ops.wan_tov:0
fabric.principalSwSelMode:0

then enable the switch with switchenable cmd.

reboot the switch with reboot cmd

take a config backup with configupload cmd

if you want to do an FOS upgrade, then do it.

For the new sw , while you first connect the hosts, check the hosts HBA driver and FW with Brocade compatibility matrix,

create a config file with cfgcreate to do the first time zoning

============================================================================================

For merging of the SWs, do the above activities but set the Fabric.ops parameters exactly same as the existing SW except Domain ID.

Then disable the new SW,

Connect the ISL ,

Enable the switch

check it with fabricshow, islshow, trunkshow.

check the utilization of the ISLs with portperfshow

Really old version of the migration planning
