swL2DevCtrlTableLockState
Module: SW-COMMON-MIB
OID (symbolic): SW-COMMON-MIB::swL2DevCtrlTableLockState
OID (numeric): 1.3.6.1.4.1.326.2.20.1.2.2.2.28.2.1.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object indicates whether the address table is locked. In other words, the address table doesn't learn any more new address. The aging timer is suspended when the address table is locked. As long as the table is locked, all of the frames are dropped if the destination can not be found in the address.
What is swL2DevCtrlTableLockState?
This object locks or unlocks the switch's MAC address table; when locked, the table stops learning new addresses and its aging timer is suspended. Admins enable the lock to freeze the current set of known MAC addresses, accepting that any frame to an unlearned destination will simply be dropped while locked. Setting this to enabled(3) would cause traffic to a newly connected, previously unseen device to be dropped instead of flooded, since the table can no longer learn it.
