Chapter 1 CLI Command Reference
protocol (ATM)
Inverse ARP is enabled for IP if the protocol is running on the interface and no static map is configured.
Subnet checking for InARP is disabled by default.
Command Modes Interface-ATM-VC configuration (for an ATM PVC or SVC)
PVC-in-range configuration (for an individual PVC within a PVC range)
PVC range configuration (for an ATM PVC range)
VC-class configuration (for a VC class)
Command History
Usage Guidelines
Command Application
Use this command to perform either of the following tasks:
• Configure a static map for an ATM PVC, SVC, or VC class.
• Enable Inverse ARP or Inverse ARP broadcasts on an ATM PVC or PVC range by configuring
Inverse ARP directly on the PVC, in the PVC range, or in a VC class (applies to IP protocol only).
• Enable the router to respond to an InARP request when the source IP address contained in the
request is not in the subnet as the receiving sub-interface on which PVC is configured.
• Enable the router to accept InARP reply when the peer router's IP address is not in the same subnet
as the receiving sub-interface on which the PVC is configured.
• Does not provide support for SVC, PVC, and SVC bundles.
PVC range and PVC-in-range configuration modes support only IP.
Examples In the following example, the router creates a static map on a VC, indicates that 10.68.34.237 is
connected to this VC, and sends ATM pseudobroadcasts:
protocol ip 10.68.34.237 broadcast
In the following example, the router removes a static map from a VC and restores the default behavior
for Inverse ARP (refer to the “Defaults” section):
no protocol ip 10.68.34.237
inarp Enables Inverse ARP on an ATM PVC. If you specify a protocol address
instead of inarp, Inverse ARP is automatically disabled for that protocol.
[no] broadcast (Optional) Indicates that this map entry is used when the corresponding
protocol sends broadcast packets to the interface. Pseudobroadcasting is
supported. The broadcast keyword of the protocol command takes
precedence if you previously configured the broadcast command on the
ATM PVC or SVC.
disable-check-subnet (Optional) Disables subnet checking for InARP.
enable-check-subnet (Optional) Enables subnet checking for InARP.
Release Modification
15.1(2)SNG Support for this command was introduced on the Cisco ASR 901 router.
