Applying Snmp Correlation Rules - Cisco ASR 9000 Serie Configuration Manuals

Applying SNMP Correlation Rules

The purpose of configuring SNMP trap correlation rules is to define the correlation rules or non-correlation
rules and apply them to specific trap destinations.
SUMMARY STEPS
1. configure
2. snmp-server correlator rule rule_name { nonrootcause trap trap_oid varbind vbind_OID { index |
value } regex line | rootcause trap trap_oid varbind vbind_OID { index | value } regex line | timeout
}
3. commit
DETAILED STEPS
Command or Action
Step 1 configure
Step 2 snmp-server correlator rule rule_name {
nonrootcause trap trap_oid varbind vbind_OID
{ index | value } regex line | rootcause trap
trap_oid varbind vbind_OID { index | value }
regex line | timeout }
Example:
RP/0/RSP0/CPU0:router(config)#
snmp-server correlator rule test
rootcause A
varbind A1 value regex RA1
varbind A2 index regex RA2
timeout 5000
nonrootcause
trap B
varbind B1 index regex RB1
varbind B2 value regex RB2
trap C
varbind C1 value regex RC1
varbind C2 value regex RC2
Step 3 commit

Implementing and Monitoring Alarms and Alarm Log Correlation
Purpose
Configures a SNMP correlation rule. You can specify the numeric
rootcause trap OID or non-rootcause trap matching definitions.
• Specifies a numeric non-rootcause trap OID and, optionally, one
or more numeric varbinds specific to the non-rootcause trap that
must ALL also be matched to have found a valid non-rootcause
for this rule. The POSIX regexp specifies a regular expression that
the value that the vbind index or value must match.
• Specifies a numeric rootcause trap OID and, optionally, one or
more numeric varbinds specific to the rootcause trap that must
ALL also be matched to have found a valid rootcause for this rule.
The POSIX regexp specifies a regular expression that the vbind
index or value must match.
You can specify the timeout for detection of a correlation after
Note
receipt of first rootcause or non-rootcause in this specified rule.
The range is from 1 to 600000 milliseconds.
All OID values for traps and varbinds are verified and rejected,
Note
if they do not match valid OIDs supported by IOS XR.
