ИЛИ

Ok, well if you have only one core, you dont really need MSTP.

On all your switches you want to do:

system-view

stp mode rstp

undo stp disable

On your core switch (4500) you want to:

system-view

stp mode rstp

stp root primary

undo stp disable

That should enable rapid spanning tree on all ports.

The "stp root primary" on your core switch will have it with

The best priority to be the root bridge (which is elected based on priority + mac address).

Статический IP

There are serveral ways but, if you have a serial console cable you can set the IP using the following process:

. Get a serial console cable.  Note that I went through several of them before I found one that would let me SEND characters to the device; I could see the switches boot activity but nothing I typed would appear on the console window… so if you have this problem, get another cable!

. Get a terminal program.  Windows Vista and 7 removed HyperTerminal (which is quite annoying) but you can download a free, fully functional version for 30 days from hilgraeve.com/hyperterminal-trial .

. Start your HyperTerminal using the following settings: connect using COM1 (or whatever port you are using) 19 200 bits/sec 8 data bits No parity 1 stop bit No flow control

. Power up your 4200G (or similar aged 3Com switch)

. In the Hyperterminal Window you will see something like, and you will have just a second or two press CONTROL+B to enter the book menu:

.   Starting……
