H3C MSR810 Command Reference Manual page 74

Parameters
slot slot-number: Specifies a card by its slot number. (Distributed devices in standalone mode.)
slot slot-number: Specifies an IRF member device by its member ID. (Centralized devices in IRF
mode.)
chassis chassis-number slot slot-number: Specifies a card on an IRF member device.
The chassis-number argument represents the member ID of the IRF member device.
The slot-number argument represents the slot number of the card. (Distributed devices in IRF
mode.)

This command is supported on distributed devices and IRF-capable centralized devices.
Specify traffic processing slots if a feature requires that all traffic on a VA interface be processed on
the same slot.
For high availability, you can specify one primary and one backup traffic processing slot by using
the service command and the service standby command, respectively.
To avoid processing slot switchover, specify the primary slot before specifying the backup slot. If you
specify the backup slot before specifying the primary slot, traffic is switched over to the primary slot
immediately after you specify the primary slot.
If you specify both primary and backup slots for an interface, traffic on that interface is processed as
follows:
• The backup slot takes over when the primary slot becomes unavailable. The backup slot
continues to process traffic for the interface after the primary slot becomes available again. The
switchover will not occur until the backup slot becomes unavailable.
• When no specified traffic processing slots are available, the traffic is processed on the slot at
which it arrives. Then, the processing slot that first becomes available again takes over.
If you do not specify a primary or a backup traffic processing slot for an i nterface, traffic on that
interface is processed on the slot at which the traffic arrives.
Examples
# (Distributed devices in standalone mode.) Specify slot 2 as the primary traffic processing slot for VA
interfaces on Virtual-Template 10.
<Sysname> system-view
[Sysname] interface virtual-template 10
[Sysname-Virtual-Template10] service slot 2
