•Path Cost – This parameter is used by the STP to determine the
best path between devices. Therefore, lower values should be
assigned to ports attached to faster media, and higher values
assigned to ports with slower media. (Path cost takes
precedence over port priority.)
- Full Range: 1-65535
- Recommended Range –
- Ethernet: 50-600
- Fast Ethernet: 10-6
- Gigabit Ethernet: 3-10
- Defaults –
- Ethernet – half duplex: 100; full duplex: 95; trunk: 90
- Fast Ethernet – half duplex: 19; full duplex: 18; trunk: 15
- Gigabit Ethernet – full duplex: 4; trunk: 3
•Fast Forwarding – You can enable this option if an interface
is attached to a LAN segment that is at the end of a bridged LAN
or to an end node. Since end-nodes cannot cause forwarding
loops, they can pass directly through to the forwarding state.
Fast Forwarding can achieve quicker convergence for
end-node workstations and servers, and also overcome other
STA related timeout problems. (Remember that Fast
Forwarding should only be enabled for ports conn ected to an
end-node device.)
- Default: disabled
