gsEL2AddressPersistence
Module: GIGAswitchEthernet-MIB
OID (symbolic): GIGAswitchEthernet-MIB::gsEL2AddressPersistence
OID (numeric): 1.3.6.1.4.1.36.2.18.39.5.1.4.1.1.1.10
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object indicates the persistence of this entry:
other(1) - This entry is currently in use but the conditions under which it will remain so are different from each of the following values.
invalid(2) - Writing this value to the object removes the corresponding entry.
permanent(3) - Address is not aged out. Additionally, if the address is seen as a source on a different port for this VLAN, the frame is filtered and the filter event is counted. Static address entries are stored in non-volatile memory and are restored to the address table following each system reset.
deleteOnReset(4) - Indicates that the entry is not aged out, however the entry is not stored in non-volatile memory. Therefore, when the device is reset, the entry will not be restored.
deleteOnTimeout(5) - Typically, address entries are learned dynamically by the switch. These entries are aged out of the table if they are not active on the network. This value correlates to this state.
What is gsEL2AddressPersistence?
Sets how this address entry persists: permanent(3) never ages out and survives a reboot (stored in non-volatile memory), deleteOnReset(4) never ages out but is lost on reboot, and deleteOnTimeout(5) is the normal dynamically-learned behavior that ages out if inactive; writing invalid(2) deletes the entry outright. Admins use permanent(3) to lock a critical server's MAC to a specific port so it can never move undetected.
