MG-SIP128 [MG-128SIPMGG]
Note 5:
When IPv6 function is in service, Ether2 IP address can be generated by MG-SIP128 [MG-
128SIPMGG] after MG-SIP128 [MG-128SIPMGG] receives the RA message from the router. So
Ether2 IP address setting is unnecessary.
Note 6:
• “set ip_version: IPv6” is executed.
When the last IP address set for Ether2 port remains, it appears.
When the last IP address set for Ether2 port does not remain,”::” appears.
When Ether2 port fails to obtain an IP address,”::” appears.
• “set ip_version: IPv4” is executed.
When the last IP address set for Ether2 port remains, it appears.
When the last IP address set for Ether2 port does not remain,”0.0.0.0” appears.
[Conditions Specific to IPv6 Function]
(1) IPv6 and IPv4 cannot be used simultaneously.
(2) IPv6 address can be set only by “stateless address autoconfiguration” in the router. So, this function re-
quires to connect a router supporting IPv6. When two or more routers exist or two or more prefixes used
for the router in the WAN side, IP address settings may be overlapped. To avoid it, this function allows
only one router to be connected in the WAN side, and one prefix can be used per router. This function
does not support allocating fixed IP addresses manually and distributing IP addresses from DHCPv6 serv-
er.
(3) When IPv6 function is in service, IPv4 packets are discarded. When a SIP request for IPv6 packet has any
IPv4 address in its message body using SDP, MG-SIP128 [MG-128SIPMGG] responses to the request
with returning 488 Not Acceptable Here. A warning code is not added to 488 Not Acceptable Here.
(4) When IPv6 function is out of service, IPv6 packets are discarded. When a SIP request for IPv4 packet has
any IPv6 address in its message body using SDP, MG-SIP128 [MG-128SIPMGG] responses to the re-
quest with returning 488 Not Acceptable Here. A warning code is not added to 488 Not Acceptable Here.
(5) When IPv6 function is in service, be sure to set an IPv6 address for each configuration command requir-
ing IP address setting.
