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
oftheactiveports.
The feature key includes distance suppor t. With firmware 06.00.00 and later, the Edge
Switch 2/12 ships standard with five buffer-to-buffer (B B) 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 F L ports was regulated in software.
Known issues
This section describes the known issues related to the E dge Switc h 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 enable d, 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 Por t 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 mo de
with the Edge Switch 2/12, Edge Switch 2/24, and Edge Switch 2/32. Transparent
mode is not supported at this tim e.
