swPortSecVLANMaxLernAddr

Module: DLINK-PORT-SECURITY-MIB

OID (symbolic): DLINK-PORT-SECURITY-MIB::swPortSecVLANMaxLernAddr

OID (numeric): 1.3.6.1.4.1.171.12.63.3.2.1.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Indicates allowable number of addresses to be learned on this VLAN. A value of -1 means no-limit. The default value is no-limit.

The max entry range is (0..N). The value N means the max number and is determined by the project itself.

What is swPortSecVLANMaxLernAddr?

This read-write integer caps the number of MAC addresses port security will learn and lock as static entries within a specific VLAN. Scoped to a VLAN rather than a single port, it lets an admin bound the number of secured hosts on a VLAN that may span multiple switch ports; -1 or the default means no limit. An admin restricting a guest VLAN to at most 50 unique locked MAC addresses would set swPortSecVLANMaxLernAddr to 50 for that VLAN entry.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.63.3.2.1.1.2
snmpwalk -v2c -c public <target> DLINK-PORT-SECURITY-MIB::swPortSecVLANMaxLernAddr

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.63.3.2.1.1.2.1
snmpget -v2c -c public <target> DLINK-PORT-SECURITY-MIB::swPortSecVLANMaxLernAddr.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.63.3.2.1.1.2.1 i <value>
