SSH命令行登录Leaf交换机后
切换到 /var/log/external这个目录下，下面的messege文件就是日志文件
ACI-93180 # cd /var/log/external
ACI-93180 # pwd
/var/log/externalACI-93180 # ls -l
total 18100
lrwxrwxrwx 1 root root 31 Mar 30 2023 dmesg -> /mnt/pss/bootlogs/current/dmesg
-rw-rw-rw- 1 root root 0 Mar 30 2023 libfipf.22193

ACI-93180 #
可以看到上面有2个messages文件
-rw-rw-rw- 1 root root 8024564 Aug 15 16:47 messages
-rw-rw-rw- 1 root root 10485822 May 13 2023 messages.1
当messages文件写满后，会产生1个新的文件，后面+数字
如何查看文件内容
可以通过more命令查看
ACI-93180# more messages
