Dillon,
I presume you are referring to the line
InARP frequency: 15 minutes(s)
In the show vc output to indicate inARP is not turned off. This is
actually a misleading display. If you turn on debug atm arp you will see
inarp generated when there is no static mapping, and they will stop when
the static mapping is configured. There was a conversation on this alias
a couple of weeks ago on this.

Subject: ATM InARP
Hi, group:
I use the static map "protocol ip 192.40.100.10 b", but the InARP is
still active. Why?
<quote>
protocol (ATM)
To configure a static map for an ATM permanent virtual circuit (PVC),
switched virtual circuit (SVC), or VC class or to enable Inverse Address
Resolution Protocol (ARP) or Inverse ARP broadcasts on an ATM PVC, use
the protocol command in the appropriate command mode. To remove a static
map or disable Inverse ARP, use the no form of this command.
Configures a static map for an ATM PVC, SVC, VC class, or VC bundle.
Enables Inverse ARP or Inverse ARP broadcasts on an ATM PVC by either
configuring Inverse ARP directly on the PVC, on the VC bundle, or in a
VC class (applies to IP and IPX protocols only).
