Basic Dial NMS Implementation Guide
Step 4
(Optional) To disable syslog messages and SNMP traps when dial interfaces go up and down, use the
commands
no logging event link-status
and
no snmp trap link-status
. Although up and down events
are legitimate events on dial interfaces, these events should not cause alarms as LAN and WAN
interfaces would.
!
interface Serial1/0/0:4:23
no logging event link-status
no snmp trap link-status
!
interface Group-Async0
no logging event link-status
no snmp trap link-status
!
In this example, only the fourth T1 of a T3 card is shown.
Note
In some Cisco IOS images, the
logging event link-status
command is disabled by
default.
Configuring the S yslog Daemon
In this case study, all the syslog messages from the access servers are sent to a single log file. The syslog
messages from the backbone routers are sent to a different log file.
To configure the syslog daemon on a Solaris syslog server, follow these steps:
Step 1
On the syslog server, edit the file syslog.conf in the /etc/ directory by using a text editor. To get syslog
working, you must add the following line to the file:
|
local0.debug /var/log/router.log
|
The local facility number is
local0.debug
. It must match the facility number configured in the
Cisco IOS device. See the
logging facility
command in Table 20.
The log file path name is
/var/log/router.log
One tab exists between the facility number and the path name. Spaces are not permitted.
You can define any directory location/path for the .txt log file.
In the following example, the new line is in
bold
:
"syslog.conf" 53 lines, 1861 characters
