DescriptionTopic
Starting with Fabric OS version 5.3.0, you can use the ipfilter command to
block unauthorized Telnet access. The option to disable Telnet using the
configure command is no longer available.
Use the following command to create a policy to block Telnet access to any station:
ipfilter --create blockTelnet -type ipv4 ipfilter --addrule
blockTelnet -sip any -dp 23 -proto tcp -act deny ipfilter
-- activate blockTelnet
Use the following command to restore default policies for IPv4:
ipfilter --activate default_ipv4 --
See the Fabric OS 5.3.0 command reference guide for more information on the
ipfilter command.

If you have purchased and installed the Secure Fabric OS option, go to the
following HP website for information on obtaining a PKI certificate: h

PKI certification
With release 5.2.0 and later, the Switch Connection Control high integrity
requirement for cascading FICON is available in the standard base Fabric OS.
End users can now deploy new cascade FICON Directors without purchasing a
separate Secure Fabric OS license.
To add a new FICON Director into existing cascaded configurations already
running Secured Fabric OS, HP recommends that users continue to deploy Secure
Fabric OS on the new FICON Director instead of migrating to FOS ACL
configuration.
NOTE:
The FC4-48 port Blade is not supported to connect to System z environments
via FICON channels or via FCP zLinux on System z. To attach the Director
to the System z environment, use an FC4-16 or FC4-32 Fibre Channel port
Blade.
FICON support
Backport tests may be run only in the following configurations:
• A pure SAN Director 2/128 (only CP2 and FC-16 blades)
• A SAN Director 2/128 with no FC4-16 blades installed, using Option 5.
Do not run backport tests in any configuration other than the two listed above; use
the minicycle test instead.
Diagnostics backport test
The following configurations will pass the spinsilk test:
• A pure SAN Director 2/128 (only CP2 and FC-16 blades)
• A pure 4/256 SAN Director, Option 5
• A pure 4/256 SAN Director, Option 5 (with FC4-16 blades)
The following configurations will fail the spinsilk test; use the minicycle test instead:
• A mixed SAN Director 2/128 (with either CP4 or FC4-16 blades)
• A pure 4/256 SAN Director, Option 1 (a pure 4/256 SAN Director refers to
a Director with CP4 and FC4-16 blades only)
