Adding an Initiator and Target Pair
Once an initiator and target have been added, connectivitybetween the two must be verified
If zoning is involved, the zoning configuration must bechecked using the cfgshow command
A way to test initiator-to-target communication is by usingthe fcping command
A device contacted by fcping could either ignore the ELSEcho request or issue an ELS ACCEPT
By default, fcping sends 5 ELS Echo requests to eachport

Maintenance Operation Impacts
Certain configuration parameters may be changed without disablingthe switch System Services such as rstatd, ruserd and telnetd
SNMP settings
Fabric Watch settings
Zoning
Firmware downloads will not disrupt the flow of data on Fabric OS v4.1and above
To avoid a disruptive firmware download to Directors, it is essentialthat these conditions are met:
HA is enabled
Heartbeat is up
CPs are in sync
Adding a new switch or Director to a fabric with a unique domain ID
will not cause a disruption New switches or Directors attempting to join a fabric with a duplicate
domain ID will cause a segmentation error

Secure Sockets Layer (SSL)
SSL provides secure access to a switch through a GUIlike Web Tools
SSL uses PKI encryption
Depending upon the CA, certificates are based on IPaddress or a fully-qualified domain name

RADIUS
When configured for RADIUS, the switch becomes aRADIUS client
With RADIUS enabled, all account passwords aremanaged through the RADIUS server
Authentication may be done from a RADIUS server, anduse the local switch database as a backup if RADIUS isunavailable
If only RADIUS is used for authentication, and unavailable,no access to the switch is possible through telnet

Passwords and Policies
Passwords should be changed on a regular basis
Administration of Fabric OS v5.1.0 account passwords consists of
these policy features: Password strength
Password history
Password expiration
Account lockout
The strength policy enforces format rules such as case, digits,punctuation and minimum length
The history policy prevents users from recycling passwords
The expiration policy forces the minimum and maximum time apassword may exist
The lockout policy allows you to set the number of failed attempts, and
the duration of the lockout When an administrator sets a users password, the history policy will
be ignored

FICON Notes
FICON is a high-speed mainframe interface
Configurable as a single-switch or cascaded fabric
Cascaded fabrics require a Secure Fabric OS license anddigital certificates from Brocades CA
Allows for port swapping Redirects resources from a failed port to a healthy port without
changing the FICON host configuration using theportswapcommand
It uses Insistent Domain IDs (IDID) Switch insists on a specific Domain ID which guarantees it
operates only with its pre-assigned Domain ID
