목표 만들기

문득 얼마전에 읽은 글이 생각난다.

 

"목표가 없는 사람은 목표있는 사람을 위해 일한다.

오늘 하루도 소중하게..."

 

나는 뚜렷한 목표를 설정하지 못했다. 아니 않았다.

목표를 만들자.

The Multiple Spanning Tree Protocol (MSTP) specifies that the system handles spanning tree packets in accordance with the MSTP protocol. When you create a new MSTP configuration on the BIG-IP LTM system, the new MSTP configuration name is not retained following a system reboot or after running the bigstart restart command. When this issue occurs, the Spanning Tree Protocol (STP) daemon retains the correct name and the BPDU packets generated by the BIG-IP system also contain the correct name, but the MSTP configuration name is not retained in the MCP database.

F5 Networks Product Development is tracking this issue as CR90249.
