MAC address

[loorra]

MAC address can build by dynamically for statics ?why?

 

[lemur]

If I understand your question correctly...

Address Resolution Protocol is used to map IP address to MAC layer address. Router has a table of currently used ARP entries. Normally table is built dynamically, but to increase network security, static entries can be added.

Im sorry I dont understand. could you try to explain one more time?

I think you are asking about changing a mac address. Mac addresses are Unique. First 6 numbers are the mfr and the second 6 are the product. They are fixed. You cant change them but you can spoof them

That's interesting. I've hard coded IP addresses, but never MAC addresses.

i swear i did not understand this question but what can i do
our teacher always give as difficult question and the way of asking the question wrong

may allah help me

If you really are determined there is always a way to do it, but for all intents and purposes hard coded. IP childs play.

Mac Address is unique to each device.

Unless you flash the EPROM

 

[lemur]

As you said, that would be spoofing, and subverting the purpose of MAC addresses.

very true. I think of spoofing more along the lines of substituting rather than changing. But you point is completely valid

what answer can i get ?!

Im still not sure what you are asking. do you want to change mac address?

this is the question!

MAC address can be stored statically or dynamically?what is the difference?in some situation we need to use statically,why?

i hope you are all here understand the question!

We do understand. MAC addresses are hard coded into the device. that is static. I dont know how it can be dynamically stored as it cant be changed

Dynamically: automaticly aasigned by router
Staticly: assigned by network administrator
MAC address table in the router can be assigned either dynamically or staticly in the router..dynamic assign work by pinging a broadcast signal to all workstations..and staticly is assigned by the network administraitor through IOS (Internetworking Operating System) which is the router OS

is this answer is correct or not ?!!

Mac table address in the router stores the mac addy's found. You cant assign mac addy dynamically because its wired to the card.

Now can the router ping (query) the workstations sure and record their mac addresses. IT cant change them
Read about IOS here Cisco IOS - Wikipedia, the free encyclopedia
