mask with all the host bits set to binary 1. This is the default broadcast address used by an IP
interface.
The broadcast parameter within the address command does not have a negate feature, which is
usually used to revert a parameter to the default value. To change the broadcast type to host-
ones after being changed to all-ones, the address command must be executed with the
broadcast parameter defined.
The broadcast format on an IP interface can be specified when the IP address is assigned or
changed.
This parameter does not affect the type of broadcasts that can be received by the IP interface. A
host sending either the local broadcast (all-ones) or the valid subnet broadcast address (host-
ones) will be received by the IP interface.
igp-inhibit — The secondary IP address should not be recognized as a local interface by the running
IGP.
static-arp
Syntax static-arp ip-addr ieee-mac-addr
no static-arp ip-addr
Context config>router>interface
Description This command configures a static Address Resolution Protocol (ARP) entry associating an IP address
with a MAC address for the core router instance. This static ARP appears 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 is replaced by the new MAC address.
The number of static-arp entries that can be configured on a single node is limited to 1000.
Static ARP is used when a 7750 SR needs to know about a device on an interface that cannot or does
not respond to ARP requests. Thus, the 7750 SR OS configuration can state that if it has a packet that
has a certain IP address to send it to the corresponding ARP address. Use proxy ARP so the 7750 SR
responds to ARP requests on behalf of another device.
The no form of the command removes a static ARP entry.
Default No static ARPs are defined.
Parameters ip-addr — Specifies the IP address for the static ARP in IP address dotted decimal notation.
ieee-mac-addr — Specifies the 48-bit MAC address for the static ARP in the form 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 addresses.
