myDynamicAddressCurrentNum
Module: MY-ADDRESS-MIB
OID (symbolic): MY-ADDRESS-MIB::myDynamicAddressCurrentNum
OID (numeric): 1.3.6.1.4.1.171.10.97.2.22.1.1.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The currunt number of dynamic MAC address .
What is myDynamicAddressCurrentNum?
This read-only Integer32 reports the current count of dynamically learned MAC addresses in the device's forwarding table. An admin monitors this against the switch's total MAC table capacity to detect when the network is approaching address-learning limits, which can cause flooding once the table fills. For example, a sudden jump in myDynamicAddressCurrentNum could indicate a MAC flooding attack or a loop causing excessive address churn.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.10.97.2.22.1.1.1 snmpwalk -v2c -c public <target> MY-ADDRESS-MIB::myDynamicAddressCurrentNum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.10.97.2.22.1.1.1.1 snmpget -v2c -c public <target> MY-ADDRESS-MIB::myDynamicAddressCurrentNum.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> myDynamicAddressCurrentNum.1
