3-130 Sun Fire B1600 Blade System Chassis Switch Administration Guide •June 2003
■The default values for Ethernet connections are 2,000,000 (half duplex),
1,000,000 (full duplex), and 500,000 (aggregated link). The default values for
Fast Ethernet connections are 200,000 (half duplex), 100,000 (full duplex), and
50,000 (aggregated link). The default values for Gigabit Ethernet connections
are 10,000 (full duplex) and 5000 (aggregated link).
Note – When the Path Cost Method is set to short (page 3-76), the maximum path
cost is 65,535.
■Admin Link Type – The link type attached to the interface. The default is Auto.
■Point-to-Point – A connection to exactly one other bridge.
■Shared – A connection to two or more bridges.
■Auto – The switch automatically determines if the interface is connected to a
point-to-point link or to shared media.
■Admin Edge Port – You can enable this option if an interface is connected 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
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, enable Edge Port only for ports
connected to an end-node device. The default for NETP0 to NETP7 is disabled.
The default for SNP0 to SNP15 is enabled and fixed at this setting.
