▓ ▓ ▓ ▓ FTIME [time]
Description
This command enables you to set up the spanning tree bridge forward delay in
milliseconds (ms) . Forward delay is the time interval spent waiting to change a port from
its spanning tree pre-forwarding state to a forwarding state. This is necessary because
every bridge on the network should ensure no loop is formed before allowing the port to
forward packets.
Parameters
Parameter Description
time Provides the time interval(ms) that you want to set up as the forward time
Example
Return message: “forward delay X (Y) ms. ”
“X” ( switch value) indicates the ftime value set by console command,
“Y” (operating value) indicates the actual operating value.
Value can be specified only on STP Mode (refer to HMIVLAUE setting).
▓ ▓ ▓ ▓ MTIME [time]
Description
This command enables you to setup the spanning tree bridge maximum age in
milliseconds (ms) . Max age is the maximum time a bridge waits without receiving
spanning tree configuration messages before attempting a reconfiguration.
