Setting Description
Switch ID The identification number of the IntraSwitch
5308FL. This value cannot be changed.
Bridge Max Age The Maximum Age timer; determines how
long the IntraSwitch 5308FL retains
information received from BPDU (bridging
Protocol Data Unit) packets.
The default value is 20 seconds. This value
cannot be changed.
Bridge Hello Time The Hello timer; controls the frequency at
which the IntraSwitch 5308FL sends a BPDU or
“hello” packet.
BPDU packets provide information to the
Spanning Tree bridges about the configuration
of the Spanning Tree network.
The default value is 2 seconds. (This causes
the switch to broadcast a BPDU packet every
two seconds.) This value cannot be changed.
Bridge Forward Delay The number of seconds a bridge must wait
before it changes a link from a listening state
to a learning state and before it changes the
link from a learning state to a forwarding state.
The default value is 15 seconds. (This means
that after a link [or the entire switch] goes
down and connectivity is re-established, the
switch waits approximately 30 seconds [twice
the default value] before it begins to forward
traffic again. This value cannot be changed.
