IES Service Configuration Commands
7750 SR OS Services Guide Page 963
Enabling the arp-populate command will remove any dynamic ARP entries learned on this interface
from the ARP cache.
The arp-populate command will fail if an existing static ARP entry exists for this interface. The arp-
populate command will fail if an existing static subscriber host on the SAP does not have both MAC
and IP addresses specified.
Once arp-populate is enabled, creating a static subscriber host on the SAP without both an IP
address and MAC address will fail.
When arp-populate is enabled, the system will not send out ARP requests for hosts that are not in the
ARP cache. Only statically configured and DHCP learned hosts are reachable through an IP interface
with arp-populate enabled. The arp-populate command can only be enabled on IES and VPRN
interfaces supporting Ethernet encapsulation.
Use the no form of the command to disable ARP cache population functions for static and dynamic
hosts on the interface. All static and dynamic host information for this interface will be removed from
the system’s ARP cache.
Default not enabled
frame-relay
Syntax frame-relay
Context config>service>ies>interface>sap
This command allows access to the context to configure the Frame Relay Local Management
Interface (LMI) operational parameters for a SONET/SDH PoS link, a DS-0 channel group, or a DS-
3/E-3 port or channel.
The port’s mode must be set to access in config>port>sonet-sdh>path>mode access context.
The port’s encapsulation type must be set to frame-relay in the config>port>sonet-
sdh>path>encap-type frame-relay context.
The no form of this command removes the Frame Relay LMI operational parameters.
