Virtual Private Fabric Hard Zones
Virtual Private Fabric (VPF) zoning divides the fabric for purposes of controlling
discovery and both inbound and outbound traffic. This type of zoning is useful for
providing security and reserving paths between devices to guarantee bandwidth.
VPF zoning is a type of hard zoning that is hardware enforced. Members can only
transmit to and receive from members of the same VPF zone. The VPF zone
boundary is secure against both inbound and outbound traffic. The following rules
apply to VPF zones:
VPF zones that include members from multiple switches must include the
ports of the inter-switch links.
VPF zones cannot cross I/O blades.
VPF zones cannot overlap; that is, a port can be a member of only one VPF
zone.
VPF zone boundaries supersede both soft and ACL zone boundaries.
Membership can be defined only by domain ID and port ID.
VPF zoning supports all port modes.
