I have a single switch (sw2), connected only to 2 pcs (192. 168. 0. 100 and 192. 168. 0. 101, connected to f0/1 and f0/2, respectively). Port security is a layer two traffic control feature on cisco catalyst switches. It enables an administrator configure individual switch ports to allow only a specified number of source mac addresses ingressing the port.
Its primary use is to deter the addition by users of dumb switches to illegally extend the reach of the. There is a similar command: Configuration on the interface level of root guard for catalyst 6500/6000 and catalyst 4500/4000 are shown below:
Switch# configure terminal enter configuration commands, one per line. On the cisco switches catalyst 2900xl, 3500xl, 2950. Open cisco packet tracer and add one router, switch and two computers to the workspace, then assign the ip address to the cisco router.
Before enabling port security, test the network connection between clients. Ping the pc0 to the router interface and pc1 to test the connection. I have the following setup on a port on my 2950:
101#sh por int fa 0/1 port security : 0 mins aging type : Absolute securestatic address aging :
Disabled maximum mac addresses : Fastethernet0/1 is a dynamic port. Like liked unlike reply.

With the switch interfaces you need to assign vlans, and you can create svis (switch virtual interfaces) to which you assign ip addresses. I'm trying to configure port security on my switch to mitigate layer 2 attacks (specifically someone plugging in a rouge switch). Assuming i have a 24 port switch i do the following:
Cisco ios allows you to configure the port security features, such as aging time and maximum macs, but port security is not actually enabled on this port. Hence, the switch basically ignores the configurations. Also, if you try on the ports that are part.
