In this section:
IP Access Control Lists (IP ACLs) specify a 5-tuple of destination IP address, destination TCP/UDP port, source IP address, source port, and transport protocol that are to be matched against the incoming IP packets. Use IP ACLs to specify rules to permit or deny packets into the SBC SWe Cloud. The IP ACL can optionally pass the traffic but at only a certain policed rate.
The destination and source IP address indicates a network mask or wild-carded instead of a fully qualified IP address. The destination and source ports, and the transport protocol is also wild-carded. While this ability to wildcard the destination (or local) IP is sufficient for basic IP ACL functionality in the dynamic address environment of the cloud, additional functionality to explicitly use a local interface and SIP Signaling Port (SSP) as the destination IP address allows more simpler and generic configurations.
The SBC SWe Cloud platform uses the local packet interface name, local management interface name, SIP signaling port number, or IP address with prefix as the destination IP address in IP ACL configuration.
When you create an IP ACL rule, its state defaults to "disabled". Change the state to "enabled" to activate the rule.
The default IP ACL supports 20 Record-Routes.
Note
When a user creates a new management group, the user must add user defined ACL rules to get the equivalent rules that are set up for the default management group.
Refer to SBC Provisioning Limits for the maximum number of IP ACLs allowed on the SBC.
The SBC SWe Cloud CLI syntax, parameter descriptions and command examples is provided below. Refer to IP Access Control List - Non-Cloud - CLI for non-Cloud equivalent CLI.

Note
- The
sourceIpAddressandsourcePortbelong to the entity that sends packets to the SBC. - The
destIpAddressanddestinationPortbelong to the SBC that receives the packets. ACLs are applicable only when an instance is receiving the packets and not when sending out the packets.

Command Parameters
IP Access Control List Parameters (Cloud)
Parameter | Length/Range | Description |
|---|---|---|
Mandatory parameters: | ||
| 1-23 | The name of the address context. The address context is a container of objects that correspond to a specific IP Addressing domain. |
| N/A | Access Control List rule name. |
| N/A | Action to take when this rule is matched.
|
| 1-255, or unlimited | The policing bucket size (in packets). A "bucketSize" represents a credit balance that should be consumed before the packets are discarded. The consumed credits reside in the bucket and gets reduced for every packet received on the Network Interface (NI). If a packet is received when the credit balance is less than the size of the packet, the packet is discarded subjected to the discard rate set in the IP Policing Alarm profile or in the Policer Alarm monitoring this Media Port. A setting of 'unlimited' allows continuous policing. (default = 50) |
destIpAddress | N/A | <IP address> – The destination IP address to match. |
destIpAddressPrefixLength | N/A | <Prefix length> – The length of destination IP address prefix to match. |
destIpInterface | 1-23 | <IP Interface name> – The name of an IP interface for destination host address. |
destIpInterfaceGroup | 1-23 | <IPIG name> – The interface group name of IP interface for destination host address. |
destMgmtIpInterface | 1-23 | <MIP name> – The name of a MGMT IP interface for destination host address. |
destMgmtIpInterfaceGroup | 1-23 | <MIPI name> – The interface group name of a MGMT IP interface for destination host address. |
destSipSigPortIndex | 1-2048 | <Destination SSP Index> – The index of SIP Signaling Port for destination address. |
destSipSigPortZone | 1-23 | <Destination SSP Zone name> – The zone name of SIP Signaling Port for destination address. |
destTypeIpVersion | N/A |
|
| 0-65535, or any |
|
| 1-10000, or unlimited |
|
| N/A | Enter IP interface name to match, or "any" to match any IP interface. |
| N/A | Enter IP interface group name to match, or "any" to match any IP interface group. |
| N/A | Enter MGMT IP interface name to match, or "any" to match any MGMT IP interface. |
| N/A | Enter MGMT IP interface group name to match, or "any" to match any MGMT IP interface group. |
| 1-65535 | Use this parameter to specify the rule precedence to control which ACL rule is applied when multiple rules match a given packet. If an incoming packet matches multiple rules, the IP ACL rule with the highest precedence (lowest numerical precedence value) is applied to that packet. Each IP ACL rule must use a unique precedence value. |
| N/A | Enter IP protocol type for use as a criterion of the IP input match. Choices are 0-255, or one of the following:
These protocols are typically associated with particular logical port values. |
| N/A | The length of source IP address prefix which must match the protocol (default = 0). |
| N/A | The source IPv4 or IPv6 address to match. (default = 0.0.0.0). NOTE: When configuring a |
| 0-65535, or any | The source IP port to match. (default = 'any') |
| N/A | Administrative state of the IP access control list rule.
|
vmAppName | N/A | The virtual machine application name against which to apply this ACL rule. If no name is specified, the rule is applied to the SBC application. |

The following example CLI ipAccessControlList commands define ACL rules to allow SSReq to receive packets on ports 3090 and 3091:
- Port 3090 is used by SSReq Server to receive XML requests over UDP from a SSReq Client.
- Port 3091 is used by SSReq Server to receive XML requests over TCP from a SSREeq Client.
