Table 337 loopback command
Description This command configures the IP maximum transmit unit (packet) for the interface.
If the configured value is less than or equal to 9194, it applies to both the control plane and the
data plan (fast path).
If the configured value is greater than 9194, then the value is applied only to the data plane and
the control plane will set the value to 9194 (control plane maximum MTU).
The no form of the command returns the default value of 1518.
Default no ip-mtu
Parameters octets — Number of octets
Values: 512 to 9194

Item Description
Syntax [no] local-proxy-arp
Context configure>service>ies>interface
Description This command enables local proxy ARP. When local proxy ARP is enabled on an IP interface,
the system responds to all ARP requests for IP addresses belonging to the subnet with its own
MAC address, and thus will become the forwarding point for all traffic between hosts in that
subnet. When local-proxy-arp is enabled, ICMP redirects on the ports associated with the
service are automatically blocked.
Default no local-proxy-arp
Item Description
Syntax [no] loopback
Context configure>service>ies>interface
Description This command specifies that the associated interface is a loopback interface that has no
associated physical interface. As a result, the associated IES interface cannot be bound to a
SAP.
Note that you can configure an IES interface as a loopback interface by issuing the loopback
command instead of the sap command. The loopback flag cannot be set on an interface where
a SAP is already defined and a SAP cannot be defined on a loopback interface.
