Configuring 4506

We are in the process of purchasing the equipment listed below:

4506 Switch

Supervisor Engine IV

48 Port 10\100\1000 UTP card

6 port GBIC card

The GBIC card will connect to 3548s.

The 3548s & the 48 Port card in the 4506 will service a 200 user environment connected to standard Desktops and servers.

My question is simple. If we were to purchase the 4506 would it be as easy as plugging in the cards and then the connectting the devices? What I'm getting at is there any configuration required if your environment is simple?

Re: Configuring 4506

The switches are pretty much plug and play for basic connectivity purpose. All ports are in VLAN 1 by default. Assign IP address to the switch for management purpose and enable "switchport mode access" and "spanning-tree portfast" for ports which directly connect to end devices such as desktops/servers/printers

If you decide to segment your network, it will involve some configuration, but should be pretty simple. You might find the following page useful

Re: Configuring 4506

Also there are some configuration examples if you are looking to do some kinds of trunking or channeling.. etc

Re: Configuring 4506

Aside from other contributors' comments, you would be well advised to configure spanning-tree portfast on all the ports connected to edge devices (i.e. not to other switches). Many devices can time out on initiation if they have to wait the default 50 seconds for spanning tree protocol to move a port into a forwarding state.

Better still, recent IOS versions allow spanning-tree portfast to be the default on all ports, so you would only need to disable it on ports connecting to other switches. Thus, if only your gigabit module (in slot 3) is used to connect to other switches, configure

spanning-tree portfast default

interface range gi3/1 - 6

no spanning-tree portfast

Hope this helps.
