The link fails between a system with a Sun GigaSwift Ethernet MMF Option X1151A and certain CISCO switches. The failure occurs when you attempt to run a DR operation on such a system that is attached to one of the following switches:
CISCO WS-c4003 switch (f/w: WS-C4003 Software, Version NmpSW: 4.4(1))
CISCO WS-c4003 switch (f/w: WS-C4003 Software, Version NmpSW: 7.1(2))
CISCO WS-c5500 switch (f/w: WS-C5500 Software, Version McpSW: 4.2(1) and NmpSW: 4.2(1))
This problem is not seen on a CISCO 6509 switch.
Workaround: Use another switch. Alternatively, you can consult Cisco for a patch for the listed switches.
