Enabling Load Sharing Between Mpus; Enabling Strict Standby Mode For The Network Ports On The Mpus - HP A7500 Series Configuration Manual

NOTE:
In an IRF fabric, the command applies to all member switches.
•
A confirmation is required when you execute this command. The command will not run if you enter N to
•
cancel the operation or fail to make a confirmation within 30 seconds.

Enabling load sharing between MPUs

By default, the active MPU and the standby MPU are not load shared, and only the active MPU forwards
traffic between LPUs. You can enable distributing inter-card traffic between the two MPUs for forwarding
efficiency.
Follow these steps to enable load sharing between MPUs:
To do...
Enter system view
Enable load sharing between
active and standby MPUs
NOTE:
Load sharing is applicable to unicast traffic only.
The A7502 switch is designed to work in load sharing mode and does not support this command.
Enabling strict standby mode for the network ports
on the MPUs
This feature is applicable only to the A7503, A7506, A7506-V, and A7510 switches that use two
LSQ1SRP2XB MPUs. The LSQ1SRP2XB MPU provides Ethernet ports for forwarding network traffic. Each
LSQ1SRP2XB MPU on your switch has one virtual LPU slot with a higher slot number than the highest real
LPU slot number. You configure the Ethernet network ports on the virtual LPU slots.
By default, strict standby is disabled, and the network ports on both MPUs can forward traffic regardless
of the active/standby state of the MPUs. If the standby MPU has a hardware failure, the network ports on
it might not be able to correctly forward data.
In strict standby mode, only the network ports on the active MPU can forward traffic. When an
active/standby switchover occurs between the MPUs, the network ports on the original active MPU go
down and the network ports on the new active MPU come up to forward traffic.
You can use the network ports on the MPUs to set up a dual-homed network, and enable strict standby
mode to increase network availability.
Follow these steps to enable active/standby mode for the Ethernet network ports on the MPUs:
To do...
Enter system view
Enable strict standby mode for the
Ethernet ports on the MPUs
Use the command...
