Subject: Access List thoughts....
Hi,
I was wondering a couple of things and wanted to know
if someone could shed some light this. Since, when
doing access lists (un-named), you use protocol number
ranges (eg.800-899 IPX Std., 100-199 IP ext., etc.)why
then do they "require" that you mention the protocol
when applying it to the interface (IP
access-group..bla bla bla) when by virtue of being
forced to use ranges this makes which protocol you are
using clear anyway.
CL: because... :-> Some people refer to this as "Cronkite" because "that's
the way it is"
Or in reverse, why are ranges
necessary if you indicate which protocol it is you're
using when you apply the list.
CL: not sure I understand this one. You can have some number of different
access lists. The access-group command ( or distribute-list ) applies the
access-list number to the particular process or interface.
Also, I am a bit confused as to when you would ever be
able to get any use out of using a wildcard mask on
the host portion of an IPX address in an access list.
What I mean by that is I can understand its use in IP
since you assign the Network.Host number but since IPX
uses the BIA of the card for the host, the odds of
having a range in any kind of sequence seems
astronomical.
CL: in the old days, so my grandfather tells me, it was possible for an
administrator to manually assign MAC's to NIC's :->
Also, I have been in environments where particular vendors used certain
manufacturers' NICs in their servers which were placed on premise. I used to
use MAC filters to screen these servers from advertising across my WAN ( the
vendor servers in each of my offices absolutely hated eachother, and would
screw things up royally if they ever saw eachother, for some reason )
Just some things that were bugging me... thanks.
CL: any time :->
