Redundant Line Control function consists of the following components:
Main unit | SPARC M10 and SPARC Enterprise | |
NIC (Network Interface Cards) | LAN card installed on the main unit and cards supported by the main unit | |
HUB (NIC switching mode) | IP address information must be configured for HUB, e.g. HUB with SNMP agent | |
Operating system (OS) |
| |
Interfaces | Physical interface | Generated by each NIC. The interface name is determined by the NIC type (e.g. hmeX and qfeX). In GS/SURE linkage mode, physical interfaces are generated through redundant line control. The interface name is shaX. |
Tagged VLAN interface | Logical interface generated by NIC that supports a tagged VLAN (IEEE802.1Q). The interface name varies depending on NIC type (e.g. ce1000, fjgi2001) | |
Virtual interface | Generated through redundant line control (e.g. sha0 and sha1). Network applications can communicate using a virtual IP address assigned to the virtual interface. In NIC switching, the virtual interface name is used technically although no virtual interface is generated. A logical IP is allocated to the actual network so that the network applications enable communication through the logical IP address. | |
Other interfaces | Link aggregation interfaces (aggr0, aggr1, etc.) and virtual NICs (vnic0, vnic1, etc.) connected to a virtual bridge are available. | |
Network number | Fast switching mode and GS/SURE linkage mode | A different network number is assigned to each physical interface and a virtual interface. |
NIC switching mode | Only one number is assigned to each network. No virtual interface is generated | |
IP address | Fast switching mode | An IP address must be allocated to each physical interface and a virtual interface. If there are two or more virtual interfaces, an IP address will be allocated to each virtual interface. Both IPv4 address and IPv6 address can be used. |
NIC switching mode | An IP address must be allocated to each logical interface. If there are two or more logical interfaces, an IP address will be allocated to each logical interface. Both IPv4 address and IPv6 address can be used. | |
GS/SURE linkage mode | An IP address must be allocated to each physical interface and a virtual interface. If there are two or more virtual interfaces, an IP address will be allocated to each virtual interface. Only IPv4 can be used. | |
