Load sharing is applicable to unicast traffic only. 
The S7902E switches are designed to work in the load sharing mode, and do not support the 
command. 
 
Enabling Active/Standby Mode for Service Ports on SRPUs 
 
If the switch uses LSQ1SRP2XB or LSQ1SRP12GB SRPUs, it simulates two virtual LPU slots with the 
slot numbers following the largest slot number. The virtual LPUs correspond to the SRPUs, and the 
Ethernet ports on the virtual LPUs correspond to the Ethernet ports on the SRPUs. If you want to 
configure the Ethernet ports on the SRPUs, you need to configure on the virtual LPUs. 
 
The SRPU LSQ1SRP2XB or LSQ1SRP12GB provides Ethernet service ports. When the S7903E, 
S7906E, S7906E-V, or S7910E switch uses LSQ1SRP2XB or LSQ1SRP12GB to operate in 
dual-SRPU mode, the service ports on the LSQ1SRP2XB or LSQ1SRP12GB work in one of the 
following mode: 
Concurrent processing mode: All services ports on both of the two SRPUs can forward data 
concurrently. If the active and standby switchover occurs due to software failure, all services ports 
on both of the two SRPUs still can forward data; however, if the active and standby switchover 
occurs due to hardware failure, the service ports on the failed SRPU may not forward data. 
Therefore, this mode is not applicable to the network environment requiring high reliability. 
Active/standby mode: Only the service ports on the active SRPU can forward data, and the service 
ports on the standby SRPU function as the backups. After the active and standby switchover 
occurs, the state of service ports on the active SRPU changes from up to down, and that of service 
ports on the standby SRPU changes from down to up. After that, the service ports on the standby 
SRPU forward data. You can realize non-interruptible forwarding through this mode. 
Follow the steps below to enable active/standby mode for service ports on SRPUs:
