<SEVERITY>
<SEVERITY> – described in point 3.
13 Set maximum size of the log file 
(optional).
esr(config)# syslog 
file-size <SIZE>
<SIZE> – file size, takes value of

esr(config)# syslog 
max-files <NUM>

remote syslog server).
esr(config)#syslog 
host <HOSTNAME> 
<ADDR><TRANSPORT

<HOSTNAME> – syslog server name, set 
by the string of up to 31 characters. Used 
only to identify the server during 
configuration. The value 'all' is used in the 
no syslog host command to delete all 
syslog servers;
<ADDR> – IP address, defined as 
AAA.BBB.CCC.DDD where each part takes 
values of [0..255];
<TRANSPORT> – data transfer protocol, 
optional parameter, takes values:
TCP – data transmission is carried
