CN4093 Application Guide for N/OS 8.2
Note: When you create an FC alias using SNMP, a default pWWN of value
10:00:00:00:00:00:00:00 is automatically assigned to the FC alias. You
must change this default pWWN value. Not doing so will result in a
conflict of pWWN IDs the next time you try to create an FC alias.
Note: The CN4093 uses hard zoning, which is enforced in the switch hardware,
based on the pWWNs of the Fibre Channel initiators and targets.
The CN4093 supports up the 64 zones per zoneset, each with up to 20 member
devices. However, when an FC alias is used, only 10 devices can be members of a
zone.
Zonesets provide a mechanism for conveniently grouping zones. Each zoneset can
contain one or more zones. A zone can belong to one or more zonesets.
Only one zoneset can be activated at a given time. If you deactivate the active
zoneset, no zonesets are active until you activate another zoneset. If you activate
one zoneset while another zoneset is active, the currently active zoneset is
deactivated.
When you activate a zoneset, the new zoneset access policies are applied.
Up to four zonesets can be configurated on the switch at any given time, though
only one can be active.
Traffic flow between end devices is restricted by default setting.Its recommended
that user should have well‐defined zoning configuration activated for security
concerns. To configure default‐zone policy, use the following command:
CN4093(config)# [no] zone default­zone permit
Define the following general properties for Fibre Channel zones and zonesets:
CN4093(config)# [no] fcalias <device alias name> wwn <port World Wide Name>
Repeat for each alias as necessary.
a. Name (or remove) the zone.
CN4093(config)# [no] zone name <zone name>
b. Add (or remove) one or more members to the zone using either pWWNs, FC
IDs, or FC Aliases
CN4093(config­zone)# [no] member pwwn <port World Wide Name>
CN4093(config­zone)# [no] member fcid <Fibre Channel ID>
CN4093(config­zone)# [no] member fcalias <device alias name>
