Table of Contents

An IP Interface Group is a named object containing one or more IP interfaces (IP addresses). The IP Interface Group is Address Context-specific (e.g. permanently bound to a particular Address Context), and is the primary tool to manage disjointed networks (separate networks that are not designed to communicate directly). An IP Interface Group is the local manifestation of a segregated network domain. The service section of an IP trunk group and a Signaling Port typically reference an IP Interface Group in order to restrict signaling and/or media activity to that IP Interface Group.

Command Parameters

IP Interface Group Parameters

1	IP Interface Group Parameters

ipInterfaceGroup

1-23

ipsec

N/A

Administrative state of the IPsec support for this interface group.

disabled (default) – IPsec support is off for all interfaces in the group.
enabled – IPsec support is on for all interfaces in the group.

ipInterface

1-23

Specifies the IP interface name.

Note

Spacevars

0	series5

Parameter

Length/Range

Description

action

N/A

Action to take when putting the IP Interface out of service:

dryUp
force

altIpAddress

N/A

Specifies alternative (secondary) IP address for the configured packet IP interface. The alternative IP address is optional, but if used must be a different IP address type than ipAddress parameter.

The following IP address types are supported:

IPv4 – This is IPv4 address in dotted decimal form (for example 128.127.50.224).
IPv6 – This is IPv6 address in hexadecimal/colon form (for example, 1280:1276:3350:2224:2222:3333:8888:1245 or fd00:21:445:128::7880).

Note
Modify the alternative IP address only after changing the Packet IP interface to disabled state.

altMediaIpAddresses

IPv4 and/or IPv6 address(es)

Use this parameter to specify up to 254 additional IPv4 and/or IPv6 media IP addresses on this IP interface. Any combination of IPv4 and IPv6 is allowed. The following rules apply when configuring alternate media IP addresses:

An IPv4/IPv6 alternate media IP address is only allowed if an IPv4/IPv6 address is defined in the primary or alternate (main) address.
An alternate media IP address must be in the same network as the primary media address (of the same IP version). Hence, CPX needs to determine the subnet based on the primary/alt IP address and primary/alt prefix, and then verify that the given alternate media address is on the same subnet.
An alternate media IP address may be added while the IP interface is enabled and in-service. However, the IP can only be deleted when the IP interface state is set to "disabled".

altPrefix

0-128

Alternative IP subnet prefix of this interface.

bandwidth

0-2147483647

Maximum amount of bandwidth allowed in units of bytes per second for this IP interface.

0 – Allow bandwidth subscriptions up to the maximum supported on the physical port.
<non-zero> – Allow up to the specified number of bytes per second on this IP interface. The aggregate of this number and all previously provisioned IP interfaces must not exceed the physical port bandwidth.

Note
When calculating bandwidth size, keep in mind that an IPv6 header size (40 bytes) is twice as large as IPv4 header (20 bytes), thus reducing the number of messages when using IPv6.

bwContingency

0-100

The percentage of maximum bandwidth reserved for contingency (that is, non-media).

The maximum bandwidth is the bandwidth normally available for media on the interface. (This is based on the configured bandwidth limit or the physical port bandwidth limit minus approximately 5% for signaling traffic). The contingency factor effectively reserves a portion of this bandwidth for non-media.

ceName

1-255

The name of the computing element that hosts the port used by this IP interface.

Note

ceName is currently not used by the

Spacevars

0	product

.

dryupTimeout

1-1440

The dry-up timeout in minutes (e.g. the number of minutes to wait for active calls to complete before dropping the call). (default = 10)

ipAddress

N/A

The primary IP Address of the Interface. The following IP address types are supported:

IPv4 – This is V4 IP address in dotted decimal form (for example 128.127.50.224).
IPv6 – This is V6 IP address in hexadecimal/colon form (for example, 1280:1276:3350:2224:2222:3333:8888:1245 or fd00:21:445:128::7880).

Note
Duplicate Address Detection procedures are performed on interfaces configured with IPv6 addresses. If a duplicate address is found in the network, a warning message is output to Linux logs at `/var/log/syslog and /var/log/messages`.

Example message:

“Nov 12 08:52:35 SBC-1 kernel: [854194.740638] mgt1: IPv6 duplicate address fc00::100:0:0:100:1 detected“

mode

N/A

The operational mode of the IP interface:

inService (default) – This state is set by default when state is enabled.
outOfService – Set mode to “outOfService” before changing the state to “disabled”.

Note
When setting `mode` to '`outOfService`', be sure to also set `state` to '`disabled`'.

portName

N/A

The physical port name used by this IP interface. Supported physical port names are:

mgmt0 – Primary Management Ethernet port for OAM.
mgmt1 – Secondary Management Ethernet port for OAM.
pkt0 – First Gigabit Ethernet port used for signaling and media traffic.
pkt1 – Second Gigabit Ethernet port used for signaling and media traffic.
pkt2 – Third Gigabit Ethernet port used for signaling and media traffic.
pkt3 – Fourth Gigabit Ethernet port used for signaling and media traffic.

Packet ports (pkt) identify the physical ports used for signaling and media, whereas media ports are UDP ports used to carry media traffic.

Note
`ipInterfaceGroup` and `ipInterface` should not be configured for mgmt0 and mgmt1 ports. Instead, configure mgmt0 and mgmt1 ports using mgmtIpInterfaceGroup and mgmtIpInterface.

prefix

0-128

Specifies the IP subnet prefix of this Interface. Default = 16.

state

N/A

Administrative state of the IP interface.

disabled (default) – In this state the IP interface is inactive and does not respond to a ping.
enabled – In this state the IP interface is active and responds to a ping if the Ethernet cable is connected.

vlanTag

1-4 digits

VLAN tags are required if more than one IP Interface is associated with a single physical port on the SBC. Enter a value from 2 to 4095

Note
The parameter “vlanTag” is exclusive on a physical port. Therefore, SBC does not create two interfaces with the same vlanTag on the same physical port.
