Description: The interface command defines an interface and enters the interface configuration mode. The interface is not usable as a routing interface until you use the ip address and no shutdown commands. There are seven types of interfaces:
- POS interfaces support Packet Over SONET/SDH (POS) Layer 3 IP traffic.
- Gigabit Ethernet interfaces interconnect to other Gigabit Ethernet compliant devices.
- Composite link interfaces consist of groups of POS interfaces that distribute traffic between the interfaces. Interfaces associated with a composite link are called "member links". POS member links inherit the layer-3 attributes of their composite link. These attributes include ip address, default peer address, and MTU size. You can configure up to 64 composite links per Avici router. Each composite link can include up to 64 POS interfaces.
- Link aggregations consist of groups of Gigabit Ethernet interfaces that form a single Layer 2 link using the IEEE 802.3ad standard. Automatic member link activation is provided via the Link Aggregation Control Protocol (LACP). The Gigabit Ethernet interface inherits a number of the link aggregation attributes including: MAC address, IP address, and MTU. Link aggregations are identified by text names of up to 20 characters.
- The single Ethernet interface supports attachment of customer network management entities to the Avici router server. This interface provides IP host functions. The exchange of routing protocol messages does not take place on Ethernet interface 0.
- The following IP interface configuration mode options and sub-commands are not available:
- IGMP interface commands and its static-group subcommand
- OSPF interface commands and its authentication-key, cost, dead-interval, hello-interval, message-digest-key, network, priority, retransmit-interval, and transmit-delay subcommands
- PIM interface commands and its sparse-mode subcommand
- Router interface commands and its IS-IS subcommands
- A management station located several hops away can reach the interface by configuring a static route from the intermediate routers to Ethernet interface 0.
NOTE There are 4 additional internal Ethernet interfaces that support communications within the Avici router. The configurations for these interfaces cannot be modified, but their status can be viewed using the show interface ethernet internal command. The following error message is displayed if you attempt to modify these interfaces:
Interfaces 1-4 not valid with new addressing.- vlan interfaces are Gigabit Ethernet or Aggregate-link subinterfaces that provide the ability to associate elements of multiple logical LANs onto a single physical network. With VLAN enabled, a port IP address, MTU, and ARP entries associated with the configured VLANs present the Avici router physical port as a group of sub-interfaces, with each sub-interface serving a sub-network or VLAN.
- Multiple virtual loopback interfaces enable you to allow your IP connections to stay up no matter what interface is used to reach a neighbor. This feature eliminates the problems of dealing with normally configured interfaces that are dependent on the performance of hardware interfaces. IPriori supports up to 10 virtual loopback interfaces on an Avici router.
- By default, a null interface is also configured at initialization. Null interfaces are used by routing protocols to discard traffic that is not addressed to their more-specific IP address without the processing overhead of access lists. Null interfaces do not require any configuration.
To configure or delete a composite-link interface:
Use the interface composite-link identifier syntax to configure a composite link and to change the command mode to set link attributes and add individual member-links.
Use the no interface composite-link identifier command syntax to delete a composite-link interface.
NOTE If you delete a composite interface that has member-links, the member links revert to POS interfaces with no layer-3 attributes defined.
To configure a Gigabit Ethernet interface:
Use the interface gbe bay/slot/port syntax to configure a Gigabit Ethernet interface.
To configure an ethernet interface:
Use the interface ethernet 0 syntax to configure an ethernet interface for the attachment of a network management station to the server.
To configure a loopback interface:
Use the interface loopback number syntax to configure a loopback interface.
To configure a POS interface:
Use the interface pos bay/slot/port syntax to configure a POS interface.
POS interfaces may be configured to operate in loopback mode to test connections. Refer to the loopback command in this chapter for information about POS loopbacks.
Factory Default: No interfaces configured.
Command Mode: Configuration.
Example 1: In the following example:
- The interface composite-link command configures a composite-link interface.
- The ip address command assigns an IP address to the composite link.
- The peer default ip address command assigns an IP address locally when connecting to devices that can't negotiate PPP, e.g. composite-link.
- The member-link pos command associates an existing POS interface with the composite link.
