Zone Distribution In Enhanced Zoning Mode - HP FlexFabric 5700 Series Configuration Manual

If the managing switch does not receive ACC packets from one or more managed switches, it
sends an RCA request to notify each managed switch to release the change authorization state.
If the managed switch replies with neither an ACC packet nor an RJT packet because of its
abnormal state, the managing switch cannot be released from its locked state. To prevent this
situation, the managing switch transmits an ACA request up to three times.
If no reply is received, the managing switch releases its locked state.
If the managing switch becomes abnormal after sending an ACA request, the managed switch
cannot receive subsequent packets. In this case, the managed switch releases its locked state
after waiting for a period of time.
4. The managing switch sends an SFC request to each managed switch. The SFC request carries data
to be synchronized, including the active zone set and zone database information. After receiving
the SFC request, the managed switch calculates the total numbers of zones, zone sets, and zone
aliases.
If none of the total numbers exceed the limit, the managed switch replies with an ACC packet.
If any of the total numbers exceed the limit, the managed switch replies with an RJT packet.
5. After receiving ACC packets from all managed switches, the managing switch sends a UFC
request to each managed switch. The UFC request notifies the managed switches to replace their
local data with the received data.
Otherwise, the managing switch sends an RCA request to notify each managed switch to release
the change authorization state.
6. After receiving the UFC request, the managed switch updates its local zone database. It replies
with an ACC packet for a successful update and with an RJT packet for a failed update.
7. After receiving ACC packets from all managed switches, the managing switch sends an RCA
request to each managed switch.
8. The managed switch releases its change authorization state and replies with an ACC packet.
9. After receiving ACC packets from all managed switches, the managing switch releases its change
authorization state.

Zone distribution in enhanced zoning mode

Enhanced zoning has the following differences from basic zoning in zone distribution:
• Enhanced zoning distributes the zone policy and hard zoning status in addition to the active zone
set and zone database.
The zone policy includes the merge control mode and default zone policy. For information about
the merge control mode, see
Enhanced zoning always performs complete distribution and does not support the zoneset
•
distribute full command.
You can use the same zone distribution methods for basic zoning as used in enhanced zoning mode.
A zoning mode switchover between basic zoning and enhanced zoning also causes zone distribution.
Switchover-triggered distribution distributes the active zone set, zone database, zone policy, and hard
zoning status.
For both switchover-triggered distribution and zone distribution in enhanced zoning mode, the SFC
request includes the zone policy whether or not the SFC request has the active zone set and zone
database.
