[no] static-arp ip-address ieee-mac-address

config>service>vprn>interface

This command configures a static address resolution protocol (ARP) entry associating a subscriber IP

address with a MAC address for the core router instance. This static ARP will appear in the core

routing ARP table. A static ARP can only be configured if it exists on the network attached to the IP

interface. If an entry for a particular IP address already exists and a new MAC address is configured

for the IP address, the existing MAC address will be replaced with the new MAC address.

The no form of this command removes a static ARP entry.

ip-address — Specifies the IP address for the static ARP in IP address dotted decimal notation.

ieee-mac-address — Specifies the 48-bit MAC address for the static ARP in the form

tos-marking-state

tos-marking-state {trusted | untrusted}

no tos-marking-state

config>service>vprn>sub-if>grp-if

This command is used to alter the default trusted state to a non-trusted state. When unset or reverted

to the trusted default, the ToS field will not be remarked by egress network IP interfaces unless the

egress network IP interface has the remark-trusted state set, in which case the egress network

interface treats all VPRN and network IP interface as untrusted.

When the ingress interface is set to untrusted, all egress network IP interfaces will remark IP packets

received on the network interface according to the egress marking definitions on each network

interface. The egress network remarking rules also apply to the ToS field of IP packets routed using

IGP shortcuts (tunneled to a remote next-hop). However, the tunnel QoS markings are always derived

from the egress network QoS definitions.

Egress marking and remarking is based on the internal forwarding class and profile state of the packet

once it reaches the egress interface. The forwarding class is derived from ingress classification

functions. The profile of a packet is either derived from ingress classification or ingress policing.

The default marking state for network IP interfaces is trusted. This is equivalent to declaring no tos-

marking-state on the network IP interface. When undefined or set to tos-marking-state trusted, the

trusted state of the interface will not be displayed when using show config or show info unless the

will not be advertised as internal IP interfaces into the IGP's link state database. For RIP, this

means that these secondary IP interfaces will not source RIP updates.

aa:bb:cc:dd:ee:ff or aa-bb-cc-dd-ee-ff where aa, bb, cc, dd, ee and ff are hexadecimal numbers.

Allowed values are any non-broadcast, non-multicast MAC and non-IEEE reserved MAC
