Follow these steps to troubleshoot IP load balancing:
Step 1 Use the show epc ip-prefix interface command with the all-entries parameter to confirm the
configuration of IP load balancing
C8540CSR-1# show epc ip-prefix interface FastEthernet 1/0/15 all-entries
Default Network Information:
Nexthop 1:
IP addr:20.0.0.1 GigabitEthernet2/0/1 (58)
Mac Addr:0090.2141.bd47
Load Balancing:Off
