Hello Holidayers:
I am working through the 3550 Doc CD and have a question regarding ARP
inspection.
I am wondering why in a non-DHCP environment I would have to create an ARP
ACL
for statically configured IP addresses.
Since ARP inspection uses the DHCP snooping binding database, why not
manually add the
static IP/MAC combination to the snooping binding database and have the
switch
work from that, since it checks every ARP packet against it? If it finds a
correct binding
it passes the packet on, if not, the switch drops the ARP packet.
Why go through the trouble of setting up the ARP ACL??
Can someone clarify this, I do not seem to see the answer in the Doc CD.
Thanks,
Bob
