The output shows that the host public key of Device A saved on Device B is consistent with the one
created on Device A.
Importing a public key from a public key file
In this example, Device A is the LB product.
Network requirements
As shown in Figure 38 , to prevent illegal access, Device B (the local device) authenticates Device A (the
peer device) through a digital signature. Before configuring authentication parameters on Device B,
configure the public key of Device A on Device B.
• Configure Device B to use the asymmetric key algorithm of RSA to authenticate Device A.
• Import the host public key of Device A from the public key file to Device B.

Configuration procedure
1. Create key pairs on Device A and export the host public key:
# Create local RSA key pairs on Device A, setting the modulus length to the default, 1024 bits.

The range of public key size is (512 ~ 2048).
NOTES: If the key modulus is greater than 512,
