Zoning
The zoning configurations are supported for Fabric Services operation on the S5000.
In Fabric Services, the
fcoe-map "default_full_fabric” has the default Zone mode set to deny. This setting
denies all the fabric connections unless included in an active zoneset. To change this setting, use the
default-zone-allow command. Changing this setting to all allows all the fabric connections without zoning.
Zoning is a mechanism to ensure only the nodes that are part of a zone can communicate with each other.
Zoning prevents unauthorized access of storage assets. A zone consists of members which are nodes
specified by adapter address, fabric address, interface, or alias. S5000 supports using World Wide Port
Name (WWPN), Fibre Channel ID (FC-ID), or alias as members of a zone.
WWPN: End device's port WWN name.
FC-ID: Switch assigned 24 bit device FC address.
Age Seconds that this route to the switch has existed.
LinkCount Number of ISL records in links array. This value will be the number of
switches attached to the named switch.
NeighborID Domain ID of connected switch.
LocalPort Port number on switch that is connected to its neighbor.
RemotePort Port number on neighbor switch.
