In general, whenthe ip keyword appears in a command, it signifies that the command is only applicable to IPv4functionality. As more features introduce IPv6 support, the ipv6 keyword is added to signify the commandis only applicable to IPv6 functionality. The ip keyword has been removed from several commands tosignify that the command has both IPv4 and IPv6 functionality.Due to this syntax change, downgrading a NetVanta 7000 Series product configured in AOS versionR10.8.0 or higher to a previous AOS version (such as AOS R10.5.x, R10.7.x), could cause servicedisruption because the new syntax might not be recognized by the previous version. Upgrading a unit froman older AOS version to AOS version R10.8.0 or later will not cause service disruption because both theold and the new syntaxes are accepted. It is recommended that a full copy (data and voice settings) ofthe configuration be saved prior to upgrading to AOS R10.8.0 and above. This can be done from theUtilities > Configuration page in the GUI.For more information on specific commands, refer to the AOS Command Reference Guide available athttps://supportforums.adtran.com.Please note that the NetVanta 7000 series does not support IPv6 at this time. If you envision needing anyIPv6 features natively on the NetVanta 7000 series, then contact your ADTRAN representative with yourrequest. In general, we recommend using an IPv6 capable ADTRAN router with the NetVanta 7000 seriesfor any IPv6 features.Default Firewall Configuration ChangesChanges were made to the default firewall configuration to increase security of voice platforms whenconnected to the Internet. These changes can impact remote phones and SIP trunking applications, but donot impact local phones on the NetVanta 7000 Series.• In AOS versions A2.01.00 through A2.03.00.SC, the default Public access control policy (ACP) allowedSIP traffic (destined for UDP port 5060) inbound. For AOS A2.04.00.SC and above, this traffic is nolonger allowed by the factory default configuration. Instead, the installer is required to selectivelycustomize the Public ACP to allow SIP traffic from remote sites and SIP trunking providers.• Units that were shipped with AOS versions through A2.03.00.SC contain a default configuration thatallows inbound SIP traffic (destined for UDP port 5060). These configurations should be modified beforeLegacy Polycom IP 430, IP 501, IP 601, IP 4000phones3.1.8 4.1.2b
