Zone name restrictions

The name value must contain the ASCII characters that actually specify the name, not including
any required fill bytes. Names must follow these rules:
•

•
McDATA Fabric mode allows the characters dash ( - ), caret ( ^ ) and dollar sign ( $ ) in zone names.

Zoning modes

Activating zones creates zone configurations on legacy McDATA switches. McDATA default zone
and safe zone modes replace the Brocade default zoning mode. You can set McDATA default zone
mode or McDATA safe zone mode, but not both. Setting the default zone enables any device in the
default zone to see any other device in the default zone. If the default zone is disabled and no
zones are active, then devices connected to the switch are unable to communicate.
Default zoning mode
The default zoning mode controls device access if zoning is not implemented or if there is no
effective zone configuration. It adds devices not explicitly zoned to a default "catch-all" zone in
M-EOS fabrics. When a device is added to a configured zone, it is automatically removed from the
default zone. Default zoning is fabric-wide and is exchanged during E_Port initialization between
adjacent switches. After the E_Port initialization, if zoning is changed, the update is propagated
throughout the fabric through a standard zone update. There is a limit of 64 devices in the default
zone. Default zoning and safe zoning cannot be active at the same time. Default zoning and safe
zoning are not available in IM3.
Default zoning should be off, but there is no check that it is turned off. The configuration is reset. If
you have a defined or effective configuration and default zoning is on, when you disable the switch
and change to McDATA Open Fabric mode, you are informed that all configurations will be lost.
Responding "yes" puts the system in McDATA Open Fabric mode with default zoning and safe
zoning turned off.
This mode is not supported in interopmode 3. For details, see "Activating Default Zones" in
11, "Administering Advanced
Safe zoning mode
The safe zoning mode is a fabric-wide parameter that ensures that the resulting zone set of two
merged fabrics is consistent with the pre-merged zone sets. When you enable the safe zoning
mode, the default zoning mode must be disabled and the zoning configuration of neighboring
switches must match completely before the zoning can merge.

Zoning using domain,index notation is allowed only in McDATA Fabric mode (IM2) only, not
Open fabric mode (IM3).
Length must be between 1 and 64 characters.
All characters must be 7-bit ASCII.
The first character must be a letter, which can be either uppercase (A-Z) or lowercase (a-z).
Any character other than the first character must be lowercase (a-z), uppercase (A-Z), a
single-digit number (0-9), dash ( - ), or underscore ( _ ).
