Use proxy ARP so the 7450 ESS 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 7450 ESS 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

Syntax
qos-route-lookup [source | destination]
no qos-route-lookup
Context
config>router>interface
config>router>interface>ipv6
Description
This command enables QoS classification of the ingress IP packets on an interface based on
the QoS information associated with routes in the forwarding table.
If the optional destination parameter is specified and the destination address of an incoming
IP packet matches a route with QoS information the packet is classified to the fc and priority
associated with that route, overriding the fc and priority/profile determined from the sap-
ingress or network qos policy associated with the IP interface. If the destination address of
the incoming packet matches a route with no QoS information the fc and priority of the
packet remain as determined by the sap-ingress or network qos policy.
If the optional source parameter is specified and the source address of an incoming IP
packet matches a route with QoS information the packet is classified to the fc and priority
associated with that route, overriding the fc and priority/profile determined from the sap-
ingress or network qos policy associated with the IP interface. If the source address of the
incoming packet matches a route with no QoS information the fc and priority of the packet
remain as determined by the sap-ingress or network qos policy.
If neither the optional source or destination parameter is present, then the default is
destination address matching.
The functionality enabled by the qos-route-lookup command can be applied to IPv4 packets
or IPv6 packets on an interface, depending on whether it is present at the interface context
(applies to IPv4) or the interface>ipv6 context (applies to IPv6). The ability to specify
source address based QoS lookup is not supported for IPv6. Subscriber management group
interfaces also do not support the source QPPB option.
The no form of the command reverts to the default.
