4.1.2 Configuring the Threshold and Cycle of TC Protect

T1600G-18TS does not support configuring the threshold and cycle of TC protect.
Select the desired unit or LAGs for configuration.
Enable or disable the Loop Protect function. It is recommended to enable this
function on root ports and alternate ports.
Loop Protect function is used to prevent loops caused by link congestions or link
failures. With Loop Protect function enabled, the port will temporarily transit to
blocking state when it does not receive BPDUs. After the link restores to normal,
the port will transit to its normal state, so loops can be prevented.
Enable or disable the Root Protect function. It is recommended to enable this
function on the designated ports of the root bridge.
Root Protect function is used to ensure that the desired root bridge will not lose
its position. With root protect function enabled, the port will temporarily transit to
blocking state when it receives higher-priority BDPUs. After two times of forward
delay, if the port does not receive any higher-priority BDPUs, it will transit to its
normal state.
Enable or disable the TC Protect function. TC Protect function is used to prevent
the switch from frequently removing MAC address entries. It is recommended to
enable this function on the ports of non-root switches.
For T1600G-18TS, with TC protect function enabled, when the switch receives
TC-BPDUs, it will not process the TC-BPDUs at once. The switch will wait for 5
seconds and process the TC-BPDUs together after receiving the first TC-BPDU,
then it will restart timing.
For other T1600G series switches, with TC protect function enabled, if the
number of the received TC-BPDUs exceeds the maximum number you set in the
TC threshold, the switch will not remove MAC address entries in the TC protect
cycle. If you enable TC Protect here, you also need to configure the TC threshold
and TC cycle in
(Optional) Configuring the Threshold and Cycle of TC
Enable or disable the BPDU Protect function. It is recommended to enable this
function on edge ports.
BPDU Protect function is used to prevent the edge port from receiving BPDUs.
With BPDU protect function enabled, the edge port will be shutdown when
it receives BPDUs, and reports these cases to the administrator. Only the
administrator can restore it.
Enable or disable the BPDU Filter function. It is recommended to enable this
function on edge ports.
BPDU filter function is to prevent BPDU flooding in the network. With BPDU filter
function enabled, the port does not receive or forward BPDUs, but it sends out its
own BPDUs, preventing the switch from being attacked by BPDUs.
