交换机配置密码策略后，登陆时出现上次登录时间。怎么取消掉呢？

使用如下命令：

info-center source { module-name | default } { console | logbuffer | logfile | loghost | monitor } { deny | level severity }

# 只允许VLAN模块的信息输出控制台，且输出信息的级别为emergency的日志信息。

<Sysname> system-view

[Sysname] info-center source default console deny

[Sysname] info-center source vlan console level emergency

同理，根据当前想要过滤掉的入职信息模块来进行过滤，例如：

%Nov 21 08:33:09:284 2021 HZB7-R1-S5130-PWR STP/6/STP_NOTIFIED_TC: Instance 0's port GigabitEthernet2/0/1 was notified a topology change.

该日志属于STP模块6级信息，过滤6级及以下（只输出5级及以上，从1到7级别依次降低）的命令：

info-center source STP monitor level notification

alert Action must be taken immediately (severity=1)
critical Critical conditions (severity=2)
debugging Debug-level messages (severity=7)
emergency System is unusable (severity=0)
error Error conditions (severity=3)
informational Informational messages (severity=6)
notification Normal but significant conditions (severity=5)
warning Warning conditions (severity=4)
