cpqn52nnHashDynamicNum
Module: CPQN5226A-MIB
OID (symbolic): CPQN5226A-MIB::cpqn52nnHashDynamicNum
OID (numeric): 1.3.6.1.4.1.232.101.2.2.7.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: A count of dynamic entries in this switch interface's Address Forwarding/Filtering mechanism.
What is cpqn52nnHashDynamicNum?
This read-only counter reports how many dynamically learned entries currently exist in this switch interface's Address Filter/Forward mechanism. An admin uses this to gauge how many distinct source MAC addresses have recently been seen on that interface, which is useful for spotting unexpected device counts. For example, a sudden spike in dynamic entry count on an access port could indicate an unauthorized hub or switch was plugged in downstream, flooding many new MAC addresses through that single port.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.232.101.2.2.7.1.2 snmpwalk -v2c -c public <target> CPQN5226A-MIB::cpqn52nnHashDynamicNum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.232.101.2.2.7.1.2.1 snmpget -v2c -c public <target> CPQN5226A-MIB::cpqn52nnHashDynamicNum.1
