hh3cMACInformationCacheLen
Module: HH3C-MAC-INFORMATION-MIB
OID (symbolic): HH3C-MAC-INFORMATION-MIB::hh3cMACInformationCacheLen
OID (numeric): 1.3.6.1.4.1.25506.2.87.1.1.7
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: The maximum queue lenth used to cache the changed MAC addresses information in the monitored device. If the value is set to 0, syslog or trap will generate as soon as there is a MAC address learnt or removed.
What is hh3cMACInformationCacheLen?
This value sets the maximum number of MAC address change records the device will buffer before emitting a syslog message or trap. Setting it to 0 makes the device notify immediately on every single MAC learn or removal event, while a higher value batches multiple changes into fewer notifications, trading immediacy for reduced notification volume. For example, on a busy access switch an admin might raise hh3cMACInformationCacheLen from the default of 50 to 200 to cut down on trap flooding during high churn periods.
