IES Interface Commands
entry will fail.
Use the no form of the command to remove a static entry from the system. The specified ip-address
and mac-address must match the host's exact IP and MAC addresses as defined when it was created.
When a static host is removed from the SAP, the corresponding anti-spoof entry and/or ARP cache
entry is also removed.
Default
none
Parameters ip ip-address — Specify this optional parameter when defining a static host. The IP address must be
mac mac-address — Specify this optional parameter when defining a static host. The MAC address
subscriber sub-ident-string — Specify this optional parameter to specify an existing subscriber
sub-profile sub-profile-name — Specify this optional parameter to specify an existing subscriber
sla-profile sla-profile-name — Specify this optional parameter to specify an existing SLA profile
ancp-string ancp-string — Specifies the ASCII string of the DSLAM circuit ID name.

configured on the SAP with a given IP address.
must be specified for anti-spoof ip-mac and arp-populate. Multiple static hosts may be
configured with the same MAC address given that each definition is distinguished by a unique IP
address.
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 SAP arp-reply-agent to determine the proper handling of received
ARP requests from subscribers.
• For VPRN SAPs with
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.
