Clearing the 16-bit Interface Indexes Not Used in the Current System
In practical networks, the network management software requires the device to provide a uniform,
stable 16-bit interface index. That is, a one-to-one relationship should be kept between the interface
name and the interface index in the same device.
For the purpose of the stability of an interface index, the system will save the 16-bit interface index when
a card or logical interface is removed.
If you repeatedly insert and remove different subcards or interface cards to create or delete a large
number of logical interfaces, the interface indexes will be used up, which will result in interface creation
failures. To avoid such a case, you can clear all 16-bit interface indexes saved but not used in the
current system in user view.
After the above operation,
z
For a re-created interface, the new interface index may not be consistent with the original one.
z
For existing interfaces, their interface indexes remain unchanged.
Follow these steps to clear the 16-bit interface indexes not used in the current system:
To do… Use the command… Remarks
Clear the 16-bit interface
indexes saved but not in use in
the current systems of the
active SRPU and the standby
SRPU (distributed device)
reset unused porttag
Required
Available in user view.
Clear the 16-bit interface
indexes saved but not in use in
the current systems of all
member devices (distributed
IRF device)
reset unused porttag
Required
Available in user view.
A confirmation is required when you execute this command. If you fail to make a confirmation within 30
seconds or enter N to cancel the operation, the command will not be executed.
Configuring the System Load Sharing Function
The S7900E series Ethernet switches support the load sharing function.
z
When the system load sharing function is enabled, the active SRPU and the standby SRPU share
the traffic that needs inter-card forwarding.
z
When the system load sharing function is disabled, only the active SRPU forwards the traffic that
needs inter-card forwarding.
Follow the steps below to enable the system load sharing function:
