Access-lists on Catalyst 3548-XL

I am trying to configure an access-list for a single port on a Catalyst 3548-XL switch. I want to only allow a range of ip addresses out through the port and deny all else.

These are the commands I have been using -

switch(Config)#access-list 6 permit 172.20.128.64 0.0.0.31

switch(Config)#end

switch(Config)#interface fastethernet0/15

switch(Config-If)#ip access-group 6 out

When I enter the last line, I get an error -

Switch(config-if)#ip access-group 6 out

^

% Invalid input detected at '^' marker.

The error is under the I in IP.

Thanks and regards,

Joe

Re: Access-lists on Catalyst 3548-XL

3500Xl won't support ACl as you are trying to implement. This is very simple layer 2 box- This access lit can onyl be applied on the vty lines to restrict the telnet access.

Switch(config)#line vty 0 4

Switch(config-line)#acc

Switch(config-line)#access-class ?

<1-199> IP access list

<1300-2699> IP expanded access list

Switch(config-line)#access-class

Hope this helps

Re: Access-lists on Catalyst 3548-XL

It there any other way I can restrict access through a port on the Catalyst 3548-XL switch without using access lists?

I am trying to restrict access through a port to a range of IP addresses.

Re: Access-lists on Catalyst 3548-XL

Without a Layer 3 device, you cannot configure access-lists. If you want to fully isolate ports, you can confiigure the port to be Protected Port. Also you can use port security feature which is based on MAC address though

Re: Access-lists on Catalyst 3548-XL

latest 2950/3550 switches does support ACLs. Am not sure if this is useful but XLs don't do it.
