IES Interface Commands
Page 956 7750 SR OS Services Guide
mac
Syntax mac ieee-address
no mac
Context config>service>ies>interface
config>service>ies>sub-if>grp-if
Description This command assigns a specific MAC address to an IES IP interface.
For Routed Central Office (CO), a group interface has no IP address explicitly configured but inherits
an address from the parent subscriber interface when needed. For example, a MAC will respond to an
ARP request when an ARP is requested for one of the IPs associated with the subscriber interface
through the group interface.
The no form of the command returns the MAC address of the IP interface to the default value.
Default The physical MAC address associated with the Ethernet interface that the SAP is configured on (the
default MAC address assigned to the interface, assigned by the system).
Parameters ieee-address — 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.
secondary
Syntax secondary {ip-address/mask | ip-address netmask} [broadcast all-ones | host-ones]
[igp-inhibit]
no secondary ip-address
Context config>service>ies>interface
Description This command assigns a secondary IP address/IP subnet/broadcast address format to the interface.
Default none
Parameters ip-address — The IP address of the IP interface. The ip-address portion of the address command
specifies the IP host address that will be used by the IP interface within the subnet. This address
must be unique within the subnet and specified in dotted decimal notation. Allowed values are IP
addresses in the range 1.0.0.0 – 223.255.255.255 (with support of /31 subnets).
mask — The subnet mask in dotted decimal notation. When the IP prefix is not specified in CIDR
notation, a space separates the ip-address from a traditional dotted decimal mask. The mask
parameter indicates the complete mask that will be used in a logical ‘AND’ function to derive the
local subnet of the IP address. Allowed values are dotted decimal addresses in the range
128.0.0.0 – 255.255.255.252. Note that a mask of 255.255.255.255 is reserved for system IP
addresses.
netmask — Specifies a string of 0s and 1s that mask or screen out the network part of an IP address so
that only the host computer part of the address remains.
broadcast — The optional broadcast parameter overrides the default broadcast address used by the
IP interface when sourcing IP broadcasts on the IP interface. If no broadcast format is specified
for the IP address, the default value is host-ones which indictates a subnet broadcast address. Use
