Configuring the ECN330-switch
2491553-KDU 137 365 Uen D 2006-06-16
• Default –
Ethernet – Half duplex: 2,000,000; full duplex: 1,000,000; trunk:
500,000
Fast Ethernet – Half duplex: 200,000; full duplex: 100,000; trunk:
50,000
Gigabit Ethernet – Full duplex: 10,000; trunk: 5,000
• Admin Link Type – The link type attached to this interface.
• Point-to-Point – A connection to exactly one other bridge.
• Shared – A connection to two or more bridges.
• Auto – The ECN330-switch automatically determines if the interface
is attached to a point-to-point link or to shared media. (This is the
default setting.)
• Admin Edge Port (Fast Forwarding) – Enable this option if an interface
is attached to a LAN segment 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 spanning tree forwarding state. Specifying Edge
Ports provides quicker convergence for devices such as workstations or
servers, retains the current forwarding database to reduce the amount
of frame flooding required to rebuild address tables during
reconfiguration events, does not cause the spanning tree to initiate
reconfiguration when the interface changes state, and also overcomes
other STA-related timeout problems. However, remember that Edge
Port should only be enabled for ports connected to an end-node device.
(Default: Disabled)
• Migration – If at any time the ECN330-switch detects STP BPDUs,
including Configuration or Topology Change Notification BPDUs, it
automatically sets the selected interface to forced STP-compatible
mode. However, the Protocol Migration button can also be used to
manually re-check the appropriate BPDU format (RSTP or STP-
compatible) to send on the selected interfaces. (Default: Disabled)
