spanning-tree link-type shared

Hi,

i 've this problem.

My PC must boot OS (windows) from network (Server sends Operating System by PC's mac-address)

PC needs a ip-address within 5-10 seconds.

I try it using hub and PC loads correctly OS and works properly.

I try on my network (without hub) using Catalyst Switch in 2 ways:

IOS and CatOS

For the IOS i find this solution:

i use the follows CLI:

spanning-tree portfast

spanning-tree link-type shared

in this case i resolved my problem.

FOR catOS , this command not work properly

i use the follows CLI:

set spantree portfast mod/port enable

set spantree link-type mod/port shared

After, if i see the configuration , i find the CLI

"set spantree mst link-type mod/port shared"

Can you help me?

Thanks

Re: spanning-tree link-type shared

Configuring a ports STP link type to shared is sort of invalid if the port is also configured as an STP portfast port. 'Shared' effectively means this is a half-duplex connection to a hub that may also be connected to another switch (hence it can't be a point-to-point link). Normal STP operation should operate over 'shared' links and you won't get the rapid start a P2P link has.

If the port is connected directly to a host then simply configuring the port as a portfast port will be enough (it will also make it a P2P link by default).

Re: spanning-tree link-type shared

Just use the "set port host" command on your client ports and this will take of your problem most likely .
