Configuring Nokia SR

How To Configure Syslog on Router Instances :

config# log
config>log# syslog <syslog-id>
config>log>syslog$ description "<description>"
config>log>syslog# address <LCP IP>
config>log>syslog# port 514
config>log>syslog# log-prefix "Nokia-SR"
config>log>syslog# facility local0
config>log>syslog# level info

NOTE : Log-prefix command is very important here and should always be configured as Nokia-SR.

Syslog Fields	Values	Description

Syslog Fields	Values	Description
syslog syslog-id	1 - 10	This command creates the context to configure a syslog target host that is capable of receiving selected syslog messages from this network element. A valid syslog-id must have the target syslog host address configured.
address ip-address	LCP IP as Syslog Destination	This command adds the syslog target host IP address to/from a syslog ID. This parameter is mandatory. If no address is configured, syslog data cannot be forwarded to the syslog target host.
facility syslog-facility	0 - 23 Default : local0	This command configures the facility code for messages sent to the syslog target host
log-prefix log-prefix-string	Nokia-SR	This command adds the string prepended to every syslog message sent to the syslog host. RFC3164, allows a alphanumeric string (tag) to be prepended to the content of every log message sent to the syslog host.
level syslog-level	emergency, alert, critical, error, warning, notice, info, debug Default : info	This command configures the syslog message severity level threshold. All messages with severity level equal to or higher than the threshold are sent to the syslog target host.
port port	514	This command configures the UDP port that will be used to send syslog messages to the syslog target host

IMPORTANT NOTE :

MxDR does not support any modification or Tampering in syslog format for Nokia SR . Below is the default log format provided and any modification or configuration in this format will not be supported.

Default Log Format : <timestamp> <hostname> <log-prefix>: <sequence> <router-name> <appname>-<severity>-<eventname>-<eventid> [<subject>]: <logmessage>

Time Stamp should be in UTC format Always . Log Prefix should be Nokia-SR always .

LCP Configuration Parameters

Table 1-2: The Nokia SR OS event collector (Syslog -3993) properties to be configured by Accenture are given in the table.

Property	Default Value	Description
Protocol	UDP	The default protocol for syslog. The collector can also accept logs in TCP. Note: While TCP offers guaranteed delivery of log packets, it places a larger overhead on the LCP. To balance TCP for reliability over UDP for speed/simplicity, contact the Accenture Security Onboarding team.
Host Names / IP Addresses	*	Logging device IP address mentioned in the Pre-Installation Questionnaire (PIQ). Note: If the device sends logs using multiple interfaces, contact the Accenture Security Onboarding team.
Signatures	Nokia-SR:	Accenture Security recommended signatures processed by the Nokia SR event collector.
Port Number	514	The default port for UDP. For TCP, the default port is 601. Note: The LCP can be configured to listen on a non-standard port, please advise the Accenture Security Onboarding team if this is a requirement.
