proxy-arp-policy
Syntax [no] proxy-arp-policy policy-name [policy-name...(up to 5 max)]
Context config>router>interface
Description
This command enables and configure proxy ARP on the interface and specifies an existing policy-
statement to analyze match and action criteria that controls the flow of routing information to and
from a given protocol, set of protocols, or a particular neighbor. The policy-name is configured in the
config>router>policy-options context.
Use proxy ARP so the router responds to ARP requests on behalf of another device. Static ARP is
used when a 7450 ESS needs to know about a device on an interface that cannot or does not respond
to ARP requests. Thus, the SR OS configuration can state that if it has a packet that has a certain IP
address to send it to the corresponding ARP address.
Default no proxy-arp-policy
Parameters
policy-name — The export route policy name. Allowed values are any string up to 32 characters long
ptp-hw-assist
Syntax [no] ptp-hw-assist
Context config>router>interface
Description
This command configures the 1588 port based timestamping assist function for the interface. Various
checks are performed to ensure that this feature can be enabled. If a check fails:
Note: The port will validate the destination IP address on received 1588 messages. If the 1588
messages are sent to a loopback address within the node rather than the address of the interface, then
the loopback address must be configured in the configure>system>security>source-address
application ptp context.
Default no ptp-hw-assist
