IPNext 190 System Installation GuideAddPac Technology Proprietary & Documentation 132 - 57interfaceFor IPNext190 to communicate with other network devices, the IP Address must be configured.The duplex and the bandwidth for connecting with other AddPac devices are set automaticallyto the optimum value. However, the duplex for connecting with other vendor’s devices may notfit to each other, In this case, the bandwidth and duplex should be set manually.The following example shows configuring the IP address of 172.20.101.100 to the interface ofFastethernet 0/0 and then the link speed of 100Mbps and full duplex manually.Table 3-22 Configuring FastethernetStep Command Description1 IP-PBX#IP-PBX# configure terminalIP-PBX(config)#Enter APOS configuration mode2 IP-PBX(config)# interface fastethernet0/0Enter interface configuration mode3 IP-PBX (config-if)# ip address172.20.101.100 255.255.0.0Configure the IP address of 172.20.101.100 to theinterface4 IP-PBX (config-if)# no speed auto If auto negotiation does not work, set to 100/full duplexmanually (Default: auto)5 IP-PBX (config-if)# speed 1006 IP-PBX (config-if)# duplex full3-23 Configuring IPv6 InterfaceStep Command Description1 IP-PBX#IP-PBX# configure terminalIP-PBX(config)#Enter APOS command entry mode2 IP-PBX(config)# interface fastethernet 0/0 Enter interface configuration mode3 IP-PBX (config-if)# ipv6 address2001:e78:b01:19:114::50/64Set the IPv6 address of‘2001:e78:b01:19:114::50/64’ to theinterfaceTable 3-24 Configuring IPv4 InterfaceStep Command Description1 IP-PBX# show run Use shown run command to verify the
