Description This command configures non-subscriber traffic profiles.
The no form of the command removes removes the profiles and disables the feature.
Parameters sub-profile sub-profile-name — Specifies an existing subscriber profile name to be associated with
the static subscriber host. The subscriber profile is configured in the config>subscr-mgmt>sub-
profile context.
sla-profile sla-profile-name — Specifies an existing SLA profile name to be associated with the
static subscriber host. The SLA profile is configured in the config>subscr-mgmt>sla-profile
context.
subscriber sub-ident-string — Specifies an existing subscriber identification profile to be associated
with the static subscriber host. The subscriber identification profile is configured in the
config>subscr-mgmt>sub-ident-policy context. The subscriber information is used by the
VPRN SAP arp-reply-agent to determine the proper handling of received ARP requests from
subscribers.
• For VPRN SAPs with
arp-reply-agent enabled with the optional sub-ident parameter, the
static subscriber host’s sub-ident-string is used to determine whether an ARP request
received on the SAP is sourced from a host belonging to the same subscriber as the
destination host. When both the destination and source hosts from the ARP request are
known on the SAP and the subscriber identifications do not match, the ARP request may be
forwarded to the rest of the VPRN destinations.
If the static subscriber host’s sub-ident string is not defined, the host is not considered to
belong to the same subscriber as another host on the SAP.
If source or destination host is unknown, the hosts are not considered to belong to the same
subscriber. ARP messages from unknown hosts are subject to anti-spoof filtering rules
applied at the SAP.
If sub-ident is not enabled on the SAP arp-reply-agent, subscriber identification matching is
not performed on ARP requests received on the SAP.
ARP requests are never forwarded back to the same SAP or within the receiving SAP’s Split
Horizon Group.
