Zoning enhancement to reduce fabric congestion

In Homogeneous Fab

ric mode, an enhancement was added to reduce u nnecessary

fabric congestio

n when performing fabric-wide zoning operations that impact the Default

Zone. This enhan

cement limits the number of members allowed in the D efault Zone to

64. When the firmware detects a zoning operation that would cause the member count

in the Default Zone to exceed 64 (such as deactivating an active zone set that has more

than 64 members), the operation is aborted and the user interface (HAFM 8.6 or EWS)

displays the following message: Zoning request denied: Operation will

cause the Defa

ult Zone to exceed its limit of 64 members.

NOTE:

This limit is d

isabled when the switch parameter Suppress Zoning RSCNs on Zone set

activations check box is enabled.

Full-fabric capability for Edge Switch 2/12

Unlike other edge switch and director products, a product feature enablem ent (PFE)

key, controls Edge Switch 2/12 E_Port-to-E_Port connections. O nce the feature key is

purchased and installed, the switch can be configured for E_Port connections on any

oftheactiveports.

The feature key includes distance support. With firmware 06.00.00 and later, the Edge

Switch 2/12 ships standard with five buffer-to-buffer (BB) credits a llocated to each port.

After activation of the Full Fabric feature on a switch, every port has 12 BB Credits

allocated to support up to 12 km links at 2Gb/s speeds.

Hard zoning for Edge Switch 2 /12 and Edge Switch 2/24 switch loop ports

Firmware 06.00.00 and later extends Hard Zoning to loop (FL) p orts on Edge Switch

2/12 and Edge Switch 2/24. Previously, zoning on FL ports was regulated in software.
