1 and H3C_A are configured as follows: (dynamic link aggregation, LACP is turned on by default).
[H3C _ A] system
[H3C _ A] cross-bridge polymerization 1
[H3C _ A] Link aggregation mode dynamics
[H3C _ A]int giabthernet 1/0/26
[h3c _ a _ giabthernet1/0/26] full duplex
[h3c _ a _ giabthernet1/0/26] speed 1000
[h3c _ a _ giabthernet1/0/26] port link relay
[h3c _ a _ giabthernet1/0/26] Port trunking allows vlan ownership.
So the other three ports are the same, and the above configuration is enough. At the same time, H3C_B is also configured as H3C_A, so check the problem of the next port.
2. Configuration of Cisco
[Cisco] Internal Port-Channel 2
[cisco]swit trunk package dot 1q
[cisco]swit mode trunking
[cisco]swit trunk allows vlan all.
[cisco] Enter port mode configuration.
[Cisco ]int gig0/ 19
[Cisco] full duplex
[Cisco] Speed 1000
[cisco]swit trunk package dot 1q
[cisco]swit mode trunking
[cisco]swit trunk allows vlan all.
[Cisco] Channel-Group 2 Mode Active
Other ports have the same configuration.
It's already configured
Use dis Link Aggregation Summary to view information in H3C switches.
At the same time, use show ethernetchannel summary to view the information of Cisco switches.
Finally, after the above configuration, the port aggregation can be connected.
Supplement: Basic usage of switch
As a basic core switch, it is used to connect multiple wired devices: The network structure is shown below, and the basic connection refers to the above method/step 1: Basic connection mode.
Used for network isolation: For some switches with good functions, you can select the network isolation mode through the mode selection switch to realize the function of network isolation. Only ordinary ports and uplink ports are allowed to communicate, and ordinary ports are isolated from each other and cannot communicate.
Besides being used as a core switch (central switch), it can also be used as an expansion switch (access switch) to expand the network.
Put it on the router and expand the network cable of the network provider (for a network with multiple IPS on one line). After the connection, different routers use different IP to connect to the public network.

Power failure:
Due to unstable external power supply, aging power cord or lightning strike, the power supply is damaged or the fan stops and cannot work normally.
Due to the power supply, other parts in the machine are often damaged.
If the power indicator on the panel is green, it is normal; If the indicator light goes out, the power supply of the switch is not normal.
This kind of problem is easy to find, solve and prevent.
In view of this kind of fault, external power supply should be done first. Generally, independent power supply is provided by introducing independent power lines and installing voltage regulators to avoid the phenomenon of instantaneous voltage being too high or too low.
If conditions permit, UPS (Uninterruptible Power Supply) can be added to ensure the normal power supply of the switch. Some UPS provide voltage stabilizing function, while others do not. Pay attention to your choice.
