Re: 3548 switch

conf t

in vlan 440

ip address x.x.x.x y.y.y.y



write mem

management is needed to bring the management interface vlan 440 to be up. otherwise it would be admin down.

You need 12.0(5)XP or higher. You should go to the latest available software.

Re: 3548 switch


This may be helpful, on the 3548 Vlan 1 is the management vlan by default and your IP address will reside on the management vlan. Too solve your problem from the switch# prompt you will need to enter the command

switch#vlan database

Switch( )#Vlan 440 name mih

switch( )#exit

switch#show vlan

now you will need to change the management vlan too vlan 440 you do this by

switch#config t

switch(config)#int vlan 440


" "#exit

switch#show int

you should now see your IP address on vlan 440 and it's state should be UP and UP

Next now the reason you cannot ping is because Vlan are seperate broadcast domaine, you will need to go through a router(layer 3 device)to ping, but now that your managment vlans are the same you should be able too ping. Since you now have more than one vlan you need to create a trunk port between your two switches

let do port number 4

switch#config t

switch(config)#int fa0/4

switch(config-if)#switchport mode trunk

" "#end

switch#show int fa0/4 switchport

/port 4 should now be a trunk port passing traffic for all vlans.

Okay man this should get you rolling. have a good one
