Alarm Information
Handling Process	First、check the configuration of radius found customer does not configuration the domain-excluded so when login it need add the domain name.After add the domain name, it still give fail Second、check the ssh configuration we found customer loss the command “ssh authentication-type default password” after add the command it can authentication success now. but the user level is too low can input any command. Third、check the user privilege level and change it to 3.
Root Cause	Configuration is wrong with SSH and radius domain.
Solution	Change the configuration as bellow: radius server group stmb radius server shared-key-cipher %^%#7&\|^Cp[sxP@`&fW1ec!;M96IuO38aQ$C=U/25=%^%# radius server authentication 172.18.10.141 1645 radius server authentication 172.18.10.157 1645 secondary radius server accounting 172.18.10.141 1646 radius server accounting 172.18.10.157 1646 secondary radius server user-name domain-excluded aaa default-domain admin Huawei authentication-scheme auth authentication-mode radius domain huawei authentication-scheme auth radius server group stmb stelnet ipv4 server enable ssh authentication-type default password ssh authorization-type default aaa # ssh server cipher aes256_ctr aes128_ctr ssh server hmac sha2_256_96 sha2_256 sha1_96 ssh server key-exchange dh_group_exchange_sha256 dh_group_exchange_sha1 ecdh_sha2_nistp256 ecdh_sha2_nistp384 ecdh_sha2_nistp521 sm2_kep ssh client first-time enable user-interface vty 0 4 authentication-mode aaa user privilege level 3
