    I don't know if it was omitted on purpose but the 'switchport port-security maximum ' is important. You refer to the default maximum being one MAC address and refer to cases - such as supporting IP phones - when more than one is needed. But you don't show how to increase the maximum.

    Thanks again for your explanation. I want to understand, what the use of using mac address aging time feature in port security? Normally a secure Mac-Address learned should remain in the mac-address table but can be changed manually if ever the need be, so that only the desirable device can access the network. What happen if at the time the aging process exhausted(using type absolute), a rogue device is connected on the same port (by unplugging the cable).

    • @JeremysITLab
      @JeremysITLab  3 роки тому +1

      Security is always a trade-off, making things less convenient to use etc. So aging is just a convenient feature that you can decide to use or not to use, although it is a trade-off for slightly less security.

    Port security is such a scary feature because you know you're going to get a million helpdesk tickets from people saying "the ethernet port broke itself". I think one of the hardest things about an IT job is trying to maintain a secure, available network without upsetting end users that don't know anything about how it works. At my previous job these kinds of things caused a lot of hostility towards the IT department.

    If i have a Cisco Switch Access-Switch for example C9300L and i configure a port that Lightweight AP will connect to and Wireless-Clients will connect to that AP.
    If i give IOS command:
    Config-if#Switchport port-security maximum 1.
    Will it go to shutdown state?
    because clients have MAC addresses and AP has MAC.
    Does switchports learn Wireless clients MAC addresses?

    Dumb question: default port-security means that only the first MAC plugged in is valid, but what happens if that first device is a switch? Since source/destination MACs change with each hop--and assuming we don't put port-security on this downstream switch--would any device connected to the switch be considered valid? Since, if I'm understanding correctly, PC A, B, and C would all read as the same MAC if filtered through a switch.

    So one time just for sh*ts and giggles I brought in my lap top to work. I work at one of the top 10 fortune 500 companies (Not going to say which). I figured their security policy would be very explicit. To test it, I changed the mac address and IP address of my personal laptop to reflect that of my work laptop. I plugged the ethernet into my laptop, Then I started a wireshark capture. I had access to all of the companies private data (encrypted of course) that was being broadcast in my subnet. So how would one go about implementing port security in a situation like that? It was quite easy for me to see the traffic and get on to the companies internal (not guest) network from my personal machine?

      Hi! If I'm not mistaken, all the questions are multiple choice :)

    Not sure if others ran into this issue, but in packet tracer, it seems that by default my switch shuts down a port whenever I "unplug" it, so I wasn't able to simulate any of this unless I kept the host connected to the switchport and just manually changed it's mac address. Strange, another odd incongruency between my version of packet tracer and yours, it's becoming very common and definitely more than a nuisance at this point.

    re: Boson, Wouldn't the port be err-disabled if prior to doing command "switchport port--security", there were 2 MAC addresses in the switch's mac address table for that port?

    Sir when I'm statically configure my pc mac address in switch which is connected to it.. It is not allowing the command. Showing duplicate mac address found... Why is that

      Did you already configure the same MAC address on a different interface?

    I enable port security on a switchport, by simply using " sw port-security" but when I attach a second device to the port it simply learns the new device's mac address and doesn't block the port or go into err-disabled. Anyone know why? I have done absolutely no other configurations to the port in question regarding port security. It is however, sw access vlan 10.

    Images in GNS3 do not work exactly the same as real Cisco devices, I tried the lab today using real Catalyst 3750 and then 2960G with a 2911 router, if you disconnect a cable, the switch will immediatly drain its MAC address table unless you manually configure the interface with [switchport port-security mac address H.H.H or sticky] but in GNS3 it doesnt.
    Also, the violation counter will reset to 0 only if you shutdown then up the inteface and connect it to the device with autorized MAC and the last source MAC will not disappear, however, in GNS3 if you disable port-security and re-enable it again, everything will reset to 0.
    these are not major problems in GNS3, but when it comes to spanning-tree it real sucks.

    Quiz 4 is incorrect - c) Unplugging the unauthorized device will also re enable the interface after 300 seconds like you showed

    Thanks, Sir. Hope you doing well.
