SNMP Support
The TLX48 2RU can be monitored via SNMP
Simple Network Management Protocol
(supports version
V2c and V3 USM). Please call our technical support staff at 1-203-647-8700 for downloadable MIB
Management Information Base
definition files.
Some entries in the SNMP configuration file (
/etc/snmp/snmpd.conf
) that users typically modify are:
•
syslocation
Text to aid in locating the unit
•
syscontact
Name/Phone/email address of a contact
•
trap2sink
IP address/name of a system to receive SNMP traps
The default name used by trap2sink is '
snmp.trap
' and is defined in the file
/etc/hosts
as pointing to
127.0.0.1. The easiest method to change the trap address is to modify the
/etc/hosts
entry and not
change the trap2sink setting in the configuration file. You may have multiple trap2sink entries in the
configuration file to specify multiple trap destinations.
NTP Support
NTP, or Network Time Protocol, is used to keep the internal clock on the TLX48 set to the correct
time.
By enabling this service, users keep the Switch
’s clock synchronized to an external time reference.
To use the service, users must have a time server running on their network or allow the Switch to access
a public time server. NTP configuration is contained in the file
/etc/ntp.conf
Details about NTP configuration may be found at:
http://tldp.org/LDP/sag/html/basic-ntp-config.html
System Log Files Support
The TLX48 2RU records system events into files located in the directory
/var/log/
.
If you wish to
preserve log files, you may redirect the logs to another system(s). This is a standard feature of Linux's
rsyslog.d
program. Redirection is enabled by entries in
rsyslog
configuration files located in
/etc/rsyslog.d/
Details about syslog configuration file entries may be found at:
Serial/RS-232 Interfaces
The Control Card has two RS-232 serial ports.
One Port is for the Linux command line interface (labeled
CONSOLE), and the other is for the Switch's ASCII command interface (labeled RS232
). If a Back-up
Control Card is installed, then its Linux console port is active, but only the RS232 port on the active Control
Card will function.
