Zone Management
3-2 8946121502
Additionally, ZONING provides:
• Greater flexibility to manage a SAN with multiple operational objectives
• Finer configuration granularity to:
— logically configure resources for improved optimization
— seclude environments for security
• Versatility – to meet application demands
Zone Enforcement
A zone is enforced through software by:
• Implementation based on Simple Name Server (SNS)
• Is enforced across all Fabric switches
SNS functionality is not degraded by supporting zones because:
• There is no change to the SNS access protocol.
• If no zones are in force an SNS queries respond with all ports.
• If one or more zones are in force an SNS query only responds with the ports that are
part of the requestor’s zone.
Setting Up Zones
ZONING supports:
• Zone creation, deletion and display
• Zone member additions and removals
Zone members can be displayed for all zones or by individual zone or configuration.
The Telnet commands are based on the three object types:
• Alias
• Configuration
• Zone
They provide five same set commands for each object type:
• Create
• Delete
• Add
• Remove
• Show
