Description This command configures the IP maximum transmit unit (packet) for the interface.
If the configured value is less than or equal to 2026, it applies to both the control plane and the
data plan (fast path).
If the configured value is greater than 2026, then the value is applied only to the data plane and
the control plane will set the value to 2026 (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>vprn>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
