Port to Vlan assignment...???

Hi,
at work we have a number of different Cisco Switches with 48 port RJ21 Telco Cards. I have an issue with assinging ports to vlans;

1. On the Cat5000 can you assign one port to a certain Vlan and another port to a another Vlan when both Ports exist on the same Telco Port block e.g. ports 1 and 5 on Port block 1-12...??? It appears that when one Port is assigned to a particular Vlan all 12 Ports are assigned to this Vlan also, is this normal?

2. Can this be done on the 4507R...???

3. If this can be done can you explain how?

Thanks

Paul

Shouldn't be much different other than you are dealing with IOS . You have to configure each interface for the vlan you want . Each interface should look like below ,where XXX is whatever vlan you want the port in .

switchport
switchport mode access
switchport access vlan XXX
 
I'm not sure if I understand the question, but if you are trying to find a way to set a group of ports to a particular vlan and with certain parameters you can use the following command:

Configuring a Range of Interfaces

The interface-range configuration mode allows you to configure multiple interfaces with the same configuration parameters. When you enter the interface-range configuration mode, all command parameters you enter are attributed to all interfaces within that range until you exit interface-range configuration mode.

Switch(config)# interface range {vlan vlan_ID - vlan_ID} | {{fastethernet | gigabitethernet | macro macro_name} slot/interface - interface} [, {vlan vlan_ID - vlan_ID} {{fastethernet | gigabitethernet | macro macro_name} slot/interface - interface}]


 
Hi Lads,
firstly thanks for your responses. Maybe I wasnt clear in my question so here's another attempt;

On Our Cat5000 there is a Telco 48 Port moduler Card, the module has four physical DB25 type interfaces that you connect the Telco RJ21 cables to. Each DB25 type interface represents 12 Fastethernet ports so with four DB25 interfaces that gives you 48 Fastethernet ports which terminate on active patch panels.
It seems when you configure 1 port for a specific Vlan the Switch assigns all 12 Ports of the particular DB25 type interface to this Vlan.

My question is therefore if it is possible to individually configure particular Fastethernet ports on a Telco Moduler Card to specific Vlans without all the ports being grouped together in the same VLAN???
Hope this is a bit clearer.

Thanks

I don't believe you can break up the vlan on those particular line cards. The bank of ports, 12 in this case will all need to be on the same vlan.
 
Thanks again Rookthis,
I though this might be the case. Do you know if it is the case with newer Cisco switches such as the 4006 and 4507R?
Thanks

On the newer hardware each port can be assigned to a particular vlan. For example on a WS-X4448-GB-RJ45 which is a 10/100/1000BaseTX (RJ45)line card, each port can be on a separate vlan altogether.

Hope that helps.
