[psm9328]

hello everyone

i need your help

After changing the switch with c9200, I cannot connect to the connected router (cisco 1921).
The following (picture attached) error message occurs in the router.

Why this error message occurs I want to know the cause and solution.
Help.

thanks

 - SSH client(s) on switches usually have limited available ciphers , use other ssh client solution such as SSH on Linux

Hello,

which SSH client are you using ? The error message is from the switch ? How is the 1921 router involved, that is, are you trying to SSH from the switch to the router, or vice versa ?

Post the output of:

show ip ssh

from both the router and the switch ?

I do not see any relation here, are you trying from Cat 9200 to connect to Router ? or from your device ?(PC)

message authentication code <- this meaning for MAC it is not mac address.
are you SSH from SW toward the Router ??
