Description

Minimum Version Requirement

88035DSQ

Network Slicing Function License(per 50GE)

Controllable feature:

The 2*50G subcard uses the standard Ethernet mode by default. To switch to the FlexEth mode, you need to purchase the license first. If the service function license is not purchased, the corresponding function cannot be used.

V800R010C00

88035DSS

Network Slicing Function License(per 100GE)

Controllable feature:

The 1*100G standard Ethernet mode is used by default. To switch to the FlexEth mode, you need to purchase the license first. If the service function license is not purchased, the corresponding function cannot be used.

Impact

If an interface on a router is directly connected to a non-Huawei device, when the router is powered off and restarted, the interface sends a signal to the peer immediately after being initialized, which probably causes data loss before configurations of the router are restored.

Run the port-tx-enabling-delay port-tx-delay-time command in the interface view to enable the interface to delay signals and set the delay.

Data loss occurs.

XGigabitEthernet interfaces are controlled by the PAF. A 10GE interface name is renamed as an XGigabitEthernet interface after upgrade through PAF. The 10G bandwidth interface configurations are lost and need to be reconfigured. After the virtual access devices master and AP are both upgraded through PAF, if the external communication interface is a 10GE interface, the external communication interface needs to be reconfigured.

Perform reconfiguration.

Configuration is lost.

Services are prevented from being interrupted without any restrictions.

If SQ rate limit is configured on a rear-end ETM subcard, the traffic statistics of outgoing packets will be greater than the actual traffic statistics after the rate limit is applied.

If SQ rate limit is configured on a rear-end ETM subcard, run the display port-queue statistics interface { interface-type interface-number | interface-name } [ cos-value ] outbound command to obtain the actual statistics of outgoing packets.

The statistics of outgoing packets are incorrect when SQ rate limit is configured on the rear-end ETM subcard.

  • When a physical interface in flexible Ethernet (FlexE) mode joins a FlexE group, services on all the FlexE interfaces in the FlexE group are intermittently interrupted, which lasts 50 ms.
  • When a physical interface in FlexE mode exits from a FlexE group, services on all the FlexE interfaces in the FlexE group are intermittently interrupted. Services on the FlexE interfaces that use timeslots of the physical interface are interrupted for 200 ms. Services on the FlexE interfaces that do not use timeslots of the physical interface are interrupted for 50 ms.

Plan services properly.

Services are interrupted intermittently during capacity expansion.

In L2VE access to L3VE scenarios, if an L2VE interface and Eth-Trunk interface are bound to the same local VSI, Layer 3 interconnection needs to be implemented between the Eth-Trunk and L3VE interfaces. The MAC address of the L3VE or Eth-Trunk interface needs to be manually changed.

Run the set access-ve-mac mac-address command in the slot view.

Change the MAC address of the L3VE interface.

Alternatively, run the mac-address mac-address command in the Eth-Trunk interface view to change the MAC address of the Eth-Trunk interface.

Layer 2 MAC flapping occurs.

After the MAC Accounting function is enabled, packet statistics are collected after a period.

None

Packet statistics are not collected in a timely manner. As a result, the statistics are incorrect.

By default, when multiple IPv4 addresses are configured on an interface, the primary and secondary addresses need to be distinguished. The sub keyword is required when you configure a secondary address. Another IPv4 address configuration mode is added. When multiple IPv4 addresses are configured on an interface, the command used to configure the primary address can be used to configure secondary addresses, without the sub keyword.

During the switching from the default mode to the new mode, no secondary IP addresses are allowed on all interfaces of the device.

Before switching the address configuration mode, delete all the secondary addresses of interfaces.

None

The permanent interface group feature is added. Only Ethernet physical interfaces and POS interfaces can be added to permanent interface groups. If the shutdown command is run in the interface group view, all member interfaces in the interface group are shut down.

Plan a proper configuration.

None

Subcard that supports FlexE: CR5D0E5XMF90

None

Only specific subcards support FlexE.

Subcard that supports FlexE: CR5D00E1NC98
