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 portstatsclearportlogclear

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 SWexcept 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
