What is the command of Huawei switch to prevent pop-up information interference?

Exit to the original privileged mode

Model identification:

LI(Lite software image) indicates that the device is a weakly functional version.

SI (standard software image) means that the device is a standard version and contains basic functions.

EI (Enhanced Software Image) indicates that the device is an enhanced version and contains some advanced functions.

HI (Super Software Image) indicates that the device is an advanced version and contains some more advanced functions.

Z, indicating that there is no uplink interface; (This position is not allowed for new products)

G. indicating the uplink GBIC interface;

P, indicating the uplink SFP interface;

T stands for uplink RJ45 interface;

V represents the uplink VDSL interface.

Difference:

The traditional Huawei switch developed from the bridge and belongs to the second layer of OSI, that is, the data link layer equipment. It addresses according to the MAC address, selects the route through the station table, and the establishment and maintenance of the station table is automatically carried out by CISCO Cisco switches. Routers belong to the third layer of OSI, that is, network layer devices.

It is addressed according to IP address and generated by routing table routing protocol. The biggest advantage of a three-layer 10 Gigabit switch is its high speed. Because the switch only needs to identify the MAC address in the frame, the algorithm of selecting the forwarding port directly according to the MAC address is simple and easy to implement in ASIC, so the forwarding speed is extremely high. However, the working mechanism of the switch also brings some problems.

1. loop: According to Huawei's switch address learning and station table establishment algorithm, loops are not allowed between switches. Once the loop exists, the spanning tree algorithm must be started to block the port that generates the loop. However, the routing protocol of routers does not have this problem, and there can be multiple paths between routers to balance the load and improve the reliability.

2. Load concentration: There can only be one path between Huawei switches, so that information can be concentrated on one communication link, which cannot be dynamically distributed to balance the load. Router routing protocol algorithm can avoid this situation. OSPF routing protocol algorithm can not only generate multiple routes, but also choose different best routes for different network applications.
