configure ports redundant
NOTE
On the BlackDiamond 10K switch, 10 Gbps modules with a serial number lower than 804405-00-09 the software
redundant port feature cover only those failures where both the TX and RX paths fail. If a single strand of fiber is
pulled on these ports, the software redundant port cannot correctly recover from the failure.To display the serial
number of the module, issue the show slot <slot_number> command. (All the modules on the BlackDiamond
8800 family of switches—formerly known as Aspen—have this serial number or higher, as does the Summit X450
switch.)
Example
The following command configures a software-controlled redundant port:
configure ports 1:3 redundant 2:3
