Nokia Network Voyager Reference Guide for IPSO 6.0 - Check Point

Ethernet InterfacesEvents that can affect the status of interfaces:• If you hot-insert a device (not power down the unit first), it appears in the lists of interfacesimmediately (after a page refresh) on the configuration pages.• If you hot-pull a device, and no configuration exists for it, it disappears from the lists ofinterfaces immediately.• If you hot-pull a device, and it had a configuration, its configuration details continue to bedisplayed and can be changed even after a reboot.• Hotswapped interfaces that are fully seated in a router’s chassis are represented in theifTable (MIB-II), ipsoCardTable (IP440-IPSO-System-MIB), and the hrNetworkTable(Host-Resources-MIB).• Unwanted configurations of absent devices can be deleted, which removes the physical andlogical interfaces from all interface lists.Configuring Tunnel InterfacesTunnel interfaces are used to encapsulate protocols inside IP packets. Use tunneling to:• Send network protocols over IP networks that don’t support them.• Encapsulate and encrypt private data to send over a public IP network.Create a tunnel logical interface by specifying an encapsulation type. Use Network Voyager toset the encapsulation type. Network Voyager supports two encapsulation types, DVMRP andGRE.The tunnel logical interface name has the form:tun0cwhere (channel number) is an instantiation identifier.Ethernet InterfacesYou can configure a number of parameters for each Ethernet interface, including the following:• Enable (make active) or disable the interface.• Change the IP address for the interface.• Change the speed and duplex mode.Configuring Ethernet InterfacesTable 3 describes the configuration settings for an Ethernet interface.Nokia Network Voyager Reference Guide for IPSO 6.0 29
