Paul,
it's good to know that I am not the only person that considers the use of a MAC address as an "alias" as being useful. It therefore strikes me as being somewhat odd that this is not included in the massive amount of options
I think the main reason is simply that no one has so far made a case for them! (I can't see the value myself, but then no one has explained it to me! I'm prepared to be enlightened.) What I would say is that, if you do want to add it as a new alias type, then I would suggest that it be added as a URL. Something like: .mac:blah-blah-blah (where l=0 and h=5 !!!) I've preceded it with a dot to indicate that it is a 323 defined URL and so avoid any conflicts with officially defined URLs. Any new aliases should probably also include what steps should be taken to enable backwards compatible operation with entities that do not understand the alias.

Paul,

Frank, At first glance, it seems odd that one would want to report that to the GK. Certainly, it doesn't seem useful to report that though LRQ or other address resolution mechanisms. However, there are cases where it might be nice if the GK knew the MAC address-- especially since V4 now allows multiple endpoints to have the same alias. There are obvious benefits to having a unique alias in the list.

pj, What about NICs serving multiple EPs? Wouldn't the EPs all have the same MAC address? Maybe this configuration doesn't make sense, though, and therefore isn't something to worry about.

Paul, Yes, that's a valid issue. The arguments I've heard in support of this is exactly as Frank had specified: it's intended to identify the physical device, more than the logical endpoint.
