I'm in the process of Upgrading port speed on 2950 and 3500 Cisco Switches. My question is, where can I find some info about how to bring all the VLAN (user ports) up to 100/FULL? I can't seem to find any docs on this.

thanks
 
try this on each port but change the port # 0/1 0/2 0/3... and so on.

switch>enable
switch#config t
switch(config)interface FastEthernet 0/1
switch(config-if)speed 100
switch(config-if)duplex full
switch(config-if)exit
switch#
 
I suggest you leave them as auto/auto . If you start hardcoding all the user ports on the switch you must hardcode all user nics also or you will have speed/duplex mismatches which will cause you all kinds of problems with the user comunity complaining about slow resaponse . If that's the way you want to go then that's fine , just seems like way too much work unless you only have a handful of users . Most nics will auto negotiate to the highest speed duplex setting by themselves , only hardcode if you need to .
 
you can also use the command

switch>enable
switch#config t
switch(config)interface range FastEthernet 0/1 -24
switch(config-if)speed 100
switch(config-if)duplex full
switch(config-if)exit
switch#

this will change all the ports in the range to value specified in one fail swoop.

Lui I tried like crazy to get the interface range command to work on my Boson Net sim.
 
FYI.

Some clients have been known to ALWAYS negotiate a 10/half duplex connection when the Catalyst int is set to auto/auto. Of course, manual int speed/duplex config has it's own problems. Be aware.

 
no but it will work on the 2950

It will work on a 3550 also. But not on a 3500xl.


It is what it is!!
