After you enter the correct password, you can log in to Switch B successfully.
When switch acts as client for publickey authentication
Network requirements
As shown in Figure 112, Switch A (the SSH client) must pass publickey authentication to log in to Switch
B (the SSH server) through the SSH protocol. Use the DSA public key algorithm.
Figure 112 Network diagram
Configuration procedure
NOTE:
During SSH server configuration, the client public key is required. Use the client software to generate a
DSA key pair on the client before configuring the SSH server.
1. Configure the SSH client.
# Create VLAN-interface 1 and assign an IP address to it.
<SwitchA> system-view
[SwitchA] interface vlan-interface 1
[SwitchA-Vlan-interface1] ip address 10.165.87.137 255.255.255.0
[SwitchA-Vlan-interface1] quit
# Generate a DSA key pair.

The range of public key size is (512 ~ 2048).
NOTES: If the key modulus is greater than 512,
It will take a few minutes.
Press CTRL+C to abort.
Input the bits of the modulus[default = 1024]:
