Full-fabric capability for Edge Switch 2/12

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

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

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

of the active ports.

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 allocated 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) ports on Edge Switch

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

Known issues

This section describes the known issues related to the Edge Switch 2/12, Edge Switch

2/24, and Edge Switch 2/32.

Certain unauthorized devices may increase response time for fabric operations

under speciﬁc conditions with the Edge Switch 2/24

When Port Binding is enabled, unauthorized devices (devices that are not set up by the

Port Binding) with older technology can transmit numerous fabric login (FLOGI) requests,

which are rejected by the Edge Switch 2/24. Processing these exchanges may increase

fabric response times for activities such as fabric builds and valid FLOGI response time

for other ports.

Workaround

Remove the unauthorized device, change the Port Binding WWN (if this device should

be authorized), or alternatively, disable Port Binding.

HSG80 transparent mode not supported with IBM AIX

Use of an HSG80 with IBM AIX is restricted to operating the HSG80 in Multibus mode

with the Edge Switch 2/12, Edge Switch 2/24, and Edge Switch 2/32. Transparent

mode is not supported at this time.
