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

ies>sub-if>grp-if: local-proxy-arp
ip-mtu
Syntax ip-mtu octets
no ip-mtu
Context config>service>ies>interface
Description
This command configures the IP maximum transmit unit (packet) for this interface.
Note that because this connects a Layer 2 to a Layer 3 service, this parameter can be adjusted under
the IES interface.
The MTU that is advertized from the IES size is:
MINIMUM((SdpOperPathMtu - EtherHeaderSize), (Configured ip-mtu)).
By default (for ethernet network interface) if no ip-mtu is configured it is (1568 - 14) = 1554.
The no form of the command returns the default value.
Default
no ip-mtu
ipcp

this context, IPCP extensions can be configured to define such things as the remote IP address and

applicable if the associated SAP/port is a PPP/MLPPP interface.
Default none
dns
Syntax dns ip-address [secondary ip-address]
dns secondary ip-address
no dns [ip-address] [secondary ip-address]
Context config>service>ies>if>ipcp
