IES Service Configuration Commands
Page 738 7750 SR OS Services Guide
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
detail parameter is given. The save config command will not store the default tos-marking-state
trusted state for network IP interfaces unless the detail parameter is also specified.
The no tos-marking-state command is used to restore the trusted state to a network IP interface. This
is equivalent to executing the tos-marking-state trusted command.
Default trusted
Parameters trusted — The default prevents the ToS field to not be remarked by egress network IP interfaces
unless the egress network IP interface has the remark-trusted state set
untrusted — Specifies that
all egress network IP interfaces will remark IP packets received on the
network interface according to the egress marking definitions on each network interface.
unnumbered
Syntax unnumbered [ip-int-name | ip-address]
no unnumbered
Context config>service>ies>interface
Description This command configures the interface as an unnumbered interface.
Parameters ip-int-name — Specifies the name of an IP interface. If the string contains special characters (#, $,
spaces, etc.), the entire string must be enclosed within double quotes.
ip-address — Specifies an IP address.
proxy-arp-policy
Syntax [no] proxy-arp policy-name [policy-name...(up to 5 max)]
Context config>service>ies>interface
config>service>ies>sub-if>grp-if
Description This command configures a proxy ARP policy for the interface.
The no form of this command disables the proxy ARP capability.
Default no proxy-arp
