hh3cMACInformationChangedTrapExt

Module: HH3C-MAC-INFORMATION-MIB

OID (symbolic): HH3C-MAC-INFORMATION-MIB::hh3cMACInformationChangedTrapExt

OID (numeric): 1.3.6.1.4.1.25506.2.87.1.4.0.1

Node type: NOTIFICATION-TYPE

Description: When the cached number of MAC address information is reached the value specified by hh3cMACInformationCacheLen, trap is generated and is sent to the remote monitoring device. The trap is also generated when the amount of time elapsed since the previous notification is greater than the interval value specified by hh3cMACInformationcSendInterval and there is at least one cached MAC address information learnt or removed. The object is valid only when hh3cMACInfomationWorkMode is set to trap(1). When the hh3cMACInfomationWorkMode is set to syslog(2), No trap will be generated even hh3cMACInformationEnabled is set to enabled(1) and the feature is enabled on interface.

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' HH3C-MAC-INFORMATION-MIB::hh3cMACInformationChangedTrapExt
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.25506.2.87.1.4.0.1

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:

zoo11-linux.zoo [UDP: [192.168.30.111]:60989->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (500008509) 57 days, 20:54:45.09
  SNMPv2-MIB::snmpTrapOID.0 = OID: HH3C-MAC-INFORMATION-MIB::hh3cMACInformationChangedTrapExt
