Device-alias mode
Basic - Expands to use the pWWN
Enhanced - Uses the native format and does not expand to the pWWN. It uses the alias instead of the pWWN.
Dynamic Port VSAN Membership
You can tie a device-alias, NWWN or PWWN to a VSAN irrespective of the interface that it is connected to.
Step 1 - Enable DPVM
MDS-1(config)# dpvm enable
Step 2 - If using device-alias, the device alias must be enhanced for DPVM
MDS-1(config)# device-alias mode enhanced
MDS-1(config)# device-alias commit
Step 3 - Configure the database
MDS-1(config)# dpvm database
MDS-1(config-dpvm-db)# device-alias JBOD1-D1 vsan 10
Successful. Commit should follow for command to take effect.
MDS-1(config)# dpvm commit
Zoning
- When you activate a zone (from any switch), all switches in the fabric receive the active zone set.
- Hard zoning cannot be disabled
- Only the active zone sets are distributed
- Active zone sets cannot be changed, without activating a full zone database.
- Each VSAN can have multiple zone sets but only one zone set can be active at any given time.
- When you create a zone set, that zone set becomes a part of the full zone set.
- When you activate a zone set, a copy of the zone set from the full zone set is used to enforce zoning, and is called the active zone set. An active zone set cannot be modified. A zone that is part of an active zone set is called an active zone.
- The administrator can modify the full zone set even if a zone set with the same name is active.
However, the modification will be enforced only upon reactivation.
Zone sets can be distributed to all switches in a fabric on a per VSAN basis. This occurs when a new E port is added or when a new zone set is activated in a VSAN.
MDS-2(config)# zoneset distribute full vsan 10
To do a one time zoneset distribution:
MDS-2# zoneset distribute vsan 10
Enhanced Zoning
- All configuration of the fabric is done form a single configuration session
- The default zone is enforced throughout the fabric
Modifying the zone database
MDS-2(config)# zone commit vsan 10
