Administering Advanced Zoning ∙ The maximum number of Peer Zones is determined by the zone database size. Refer to Zone database size on page 320 for information on zone database sizing. Firmware upgrade and downgrade considerations for Peer Zoning When a switch containing Peer Zones is upgraded to Fabric OS 7.4.0, Peer Zoning connectivity rules are enforced on the devices attached to the upgraded switch. If the device is a member of a Peer Zone, the upgrade can cause disruption. When a switch containing Peer Zones is downgraded from Fabric OS 7.4.0 to an earlier version, the Peer Zones are treated as regular zones and the zones follow the regular zoning connectivity rules. All devices in the Peer Zone must be attached to switches running Fabric OS 7.4.0 or later, for the Peer Zoning connectivity rules to be applied. If any device that is part of the Peer Zone is attached to a switch running an earlier version of Fabric OS, the Peer Zone will be treated as a regular zone. After downgrading to an earlier version of Fabric OS, Peer Zoning connectivity rules remain on the switch until a port of the Peer Zone device is toggled or a new zoning configuration is committed. In such a case, the regular zoning rules apply to the Peer Zones. LSAN and QoS Peer Zoning considerations LSAN and QoS Peer Zoning are supported. LSAN Peer Zoning is supported on Edge to edge and Edge to backbone topologies. Once the zoning configuration is enabled, Peer Zoning rules are followed QoS Peer Zones are supported as long as the zone name has the prefix "QOSH" or "QOSL" in the zone name. Refer to QoS on page 388 for more information. Peer Zone configuration Peer Zones are configured and managed using zone commands with the --peerzone option. In the Peer Zone, devices must be identified as either WWN or D,I devices. Mixing WWN and D,I device identification within a single Peer Zone is not allowed. Aliases are not supported as devices for a Peer Zone. Creating Peer Zones To create a Peer Zone configuration, complete the following steps. 1. Connect to the switch and log in using an account with admin permissions. 2. Create Peer Zones using the zonecreate --peerzone command. The -members operand is optional. The following example creates two Peer Zones. The first Peer Zone is called "peerzone_wwn_mbrs", which contains "10:00:00:00:01:1e:20:20" as the principal device and "10:00:00:02:1f:02:00:01" and "10:00:05:1e:a9:20:00:01" as the nonprincipal devices. The second Peer Zone is called "peerzone_di_mbrs", which contains "10,1" as the principal device and "20,1" and "20,2" as the non-principal devices. switch:admin> zonecreate --peerzone peerzone_wwn_mbrs -principal "10:00:00:00:01:1e:20:20"/ -members "10:00:00:02:1f:02:00:01;10:00:05:1e:a9:20:00:01" switch:admin> zonecreate --peerzone peerzone_di_mbrs -principal "10,1" -members "20,1;20,2" Brocade Fabric OS Administration Guide, 8.0.1 53-1004111-02 345
