 It is recommended that for directors with more than 300 E_Ports, the switch be disabled prior
to executing the “switchCfgTrunk” command (used to disable or enable trunking on the
switch).
 During non-disruptive firmware upgrades, E_Ports in R-RDY mode may cause some frame
drops on the E-port links.
 The Brocade Network Advisor seed switch should always have the highest FOS version used in
the fabric.
 For login authentication through RADIUS, Brocade switch should be able to reach RADIUS
servers through TCP authentication port (default 1812) and accounting port (default 1813).
Both of these ports must be kept open in any firewall settings.
 When a firmware upgrade on a Brocade 6510 switch initiated through Brocade Network
Advisor results with “failed to enforce new iptable rules” error message, the switch could be
inaccessible via SSH and/or Telnet. Activating (from console) a new policy with rules of
default active policy will restore access to the switch.
