思科2950的问题

不可以了。
但是可以设置成spanning-tree uplinkfast

%Warning: portfast should only be enabled on ports connected to a single host.
Connecting hubs, concentrators, switches, bridges, etc.to this interface
when portfast is enabled, can cause temporary spanning tree loops.
Use with CAUTION

%Portfast has been configured on FastEthernet0/12 but will only
have effect when the interface is in a non-trunking mode.

spanning-tree portfast trunk
你试试这句能不能执行 不行的话就是不能
有的交换机支持trunk的portfast
2950我没试过

可以
