在維護已久的UCSM (FI6xxx) series總是容易見著這樣的錯誤訊息。不去理會其它不會對維運設備造成太大影響，只是偶而客戶問及總不希望有個錯誤訊息掛載在那兒。
Resolution :
step01. SSH login UCSM
step02. # scope security
step03. /security# scope keyring default
step04./security/keyring# set regenerate yes
step05./security/keyring* commit-buffer // 套用立即生效
等待幾分鐘這個錯誤訊息即會消失..^O^
Rerfernce :
它能夠登入重點在於前面一定要帶 " ucs- " 才能登入就對了。
