O&M capability: support restart operations on distributed switches: support reporting alarms for failed upgrade of distributed switches. Control capability: Configurations can be directly delivered to distributed switches (remote modules).

Control capability: support direct configuration delivery to distributed switches (remote modules).

Management capability: You can view the information of the distributed switch based on the central switch, including the ESN, model, online status, interface directly connected to the central switch, and the port list information of the distributed switch itself.

Monitoring capability: You can view the memory usage, storage space usage, and temperature of distributed switches, as well as the running status, rate, flow rate, packet statistics, and bandwidth utilization of distributed switch ports.

When the authentication point and the group policy execution point are not on the same device, you need to use the policy linkage function.

In the policy linkage scenario, you need to set the downstream port type of the Edge device to Extended Access Switch

The policy linkage function means that no matter where you go, the permission to access resources is the same, and it is decoupled from the IP address.

When the authentication point, access point, and group policy execution point are all connected to the device, the policy linkage function should be used

The maximum number of XSIC slots can reach 4.

The maximum number of WSIC slots can reach 4.

4 SIC slots.

Dual master control and double forwarding

and the two upstream traffic paths of the edge form ECMP load balancing

Different source CIDR blocks choose different main exits

Different EDGE devices choose different main outlets

Different upstream network segments choose different main exits

If the Flag value of the migration attribute in the MAC address route is 1, it indicates a static MAC address, and the static MAC address is preferred.

When a MAC address route is migrated, the large sequence number in the MAC migration attribute is preferred.

and MAC address routes are filled with two labels (that is, both mplslable1 and mplslable2 are valid in packets).

The Route Distinguisher value (RD value) of the MAC route is generated by the value configured by the evpn source-address

All of the above statements are correct

Used in relocation scenarios, this tool can restore the user's existing network networking status and service characteristics information

It is used in relocation scenarios, mainly used to formulate relocation plans and design the networking structure of new networks

It is used in relocation scenarios, mainly used to translate the configuration of friends in batches and improve the efficiency of relocation

The COST configuration of the MSTP link of the remote operator is larger, and it is recommended to configure 1000 to avoid traffic bypassing through the WAN link - the test is wrong

The COST configuration of the link of WDM or bare fiber in the same city is the second smallest, and it is recommended to configure 200 to ensure that the route calculation is secondary to the same city link

The COST value of the local link is the smallest, and it is recommended to configure 10 toensure that the route calculation gives priority to the local link test error

The link cost between the RR and the PE is extra-large, and it is recommended to set 10,000 to ensure that the RR device is only responsible for control plane route reflection and does not forward traffic

Monitoring: V5 is based on http 2.0 channel, and Spruce is based on telemetry channel (GRPC). O&M: Based on the SSH channel, V5 is different from Spruce.

O&M: Based on the SSH channel, V5 is different from Spruce.

Acceptance: Based on the netconf channel, V5 is no different from Spruce.

Configuration/alarm: Carried on the netconf channel, the yang model is different, and the spruce adopts the yang 2.0 model.

04, 06, and 10 main control boards cannot be shared

The main controller does not provide a business port

The main control and switching are integrated, and the centralized architecture has a lower switching delay

Global services such as local load tuning and load balancing of the LeaderAP are limited by the performance of the AP, and the specifications of the APs that can be managed by theLeaderAP are limited

If the specifications are exceeded, if APs are not grouped, APs will be randomly grouped, and adjacent APs and APs on the same floor may be assigned to different groups, which will affect global services such as tuning and load balancing

AP groups in the current version are grouped through AP management VLANs, and APs in the same group need to have the same management VLANs

The AP tuning group division will be reflected on the controller of the current version

Rapid deployment, which can support plug-and-play of tenant devices

Remote O&M can be achieved through the NETCONF protocol

In the solution, the NCE platform can provide API interfaces to connect with upper-layer applications

You cannot switch between the local management mode and the cloud management mode of Huawei devices

Delete it directly in NCE-Campus

Add the command line on the device, and then delete it through NCE-Campus

No other operations are required, NCE-Campus will reconcile

Support 2G large cache to cope with high burst business traffic.

It can be used as a remote module for the central switch to achieve simplified networking.

It supports advanced features such as VxLAN and MPLS, real-time telemetry data collection, and network O&M visualization, which can be widely used in scenarios such as medium-sized campus aggregation and small campus cores.

3 power supply design, support N+1 redundancy, full 802.3bt90W PoE++ power supply for all ports, and the maximum PoE output power of the whole machine can reach 2268W, adapting to the power supply needs of massive terminals.

Distributed gateway - VxLAN to access, independent AC scenario, for wireless traffic, local forwarding mode is not recommended.

Distributed gateway - VxLAN to access, independent AC scenario, from the edge to the VN, on the edge to execute the service accompanying policy (the edge needs to subscribe to the IP-Group service), the current solution has supported automatic deployment.

The VTEP device is both an L2 gateway and an L3 gateway. The non-gateway node is not aware of the VXLAN tunnel and acts only as the forwarding node for VXLAN packets.

Distributed gateway - VxLAN to aggregation, AC on the board, the wireless traffic service accompanying policy is executed on the edge, and tunnel forwarding is recommended.
