Table 302 Enable information output to a monitor terminal
Operation Command
Enter system view system-view
Enable the information info-center enable

Enable information info-center monitor channel
output to Telnet { channel-number |

Define an information info-center source { modu-name
source | default } channel
{ channel-number |
channel-name } [ { log | trap |
debug } * { level severity | state
state } * ]
Set the format of time info-center timestamp { log |
stamp trap | debugging } { boot | date
| none }
When there are multiple Telnet users or dumb terminal users, some configuration
parameters (including module filter, language and severity level threshold settings) are
shared between them. In this case, change to any such parameter made by one user
will also be reflected on all other user terminals.
To view debug information of specific modules, you need to set the information type
as debug in the info-center source command, and enable debugging on
corresponding modules with the debugging command as well.
To view output debug/log/trap information on the monitor terminal, you should also
enable the corresponding debug/log/trap display on the switch.
For example, to view log information of the switch on a monitor terminal, you need
to not only enable log information output to the monitor terminal, but also enable
log terminal display with the terminal logging command.
