- Vxinterface - Configures a virtual interface in the cluster.
A vinterface is a VRRP (Virtual Router Redundancy Protocol) construction that allows a backup system for ethernet interfaces. It does so by updating and advertising MAC-to-IP address mappings. A VRRP virtual router defines a MAC address for an interface. The Acme Packet Net-Net OS-E and Net-Net 2600 (formerly Covergence CXC-354) loads that address onto the Ethernet interface acting as the master host. If that interface goes down, the Acme Packet Net-Net OS-E and Net-Net 2600 moves that MAC address to the next priority interface, using ARP to broadcast the MAC-to-IP mapping.
- Admin - Enables and disables this VRRP virtual interface.
- preempt (advanced) - Specifies whether the configured master vinterface should retake the mastership if it has gone down and then returned to operations. If set to true, the master resumes its position. If set to false, the backup interface retains master control.
- Group - Groups VRRP interfaces for failover purposes. If you assign a vinterface a group number of 0, it does not participate in grouping.
- preempt-delay - Specifies whether the Acme Packet Net-Net OS-E and Net-Net 2600 should wait for a period of time before restoring the master (if preempt is set to true).
- gratuitous-arp-count - Specifies the number of gratuitous ARP (Address Resolution Protocol) packets to send. The Acme Packet Net-Net OS-E and Net-Net 2600 uses gratuitous ARP to keep other devices informed of the IP-to-MAC address mapping of the current master vinterface.
- gratuitous-arp-interval - Specifies the number of seconds between gratuitous ARP packets if the count is set to greater than 1.
- gratuitous-arp-period - Specifies the number of seconds the Acme Packet Net-Net 2610 waits between completing the previous gratuitous ARP count/interval, and beginning the next. For example, if you set the count to 2, the interval to 3, and the period to 10, the Acme Packet Net-Net OS-E and Net-Net 2600 sends out a GARP, waits 3 seconds and then sends another. After 10 seconds, the Acme Packet Net-Net OS-E and Net-Net 2600 begins again. A value of 0 sets the Acme Packet Net-Net OS-E and Net-Net 2600 to only send out the first alerting GARP packets.
- host-interface - Sets the Ethernet interfaces to be used as part of the VRRP resources. Re-execute the command for each interface in the VRRP pool. The order of priority is established by your order of entry (first is highest).
You can configure two or more ethernet interfaces on a box, but the boxes must be grouped. For example, all box 2 instances must occur in a row, but groups need not be in numerical order (e.g., box 2, box 2, box 1, box 3). A box must fail fully (all interfaces) before the Acme Packet Net-Net OS-E and Net-Net 2600 seeks connectivity with the next box in the configuration.
Additionally, each Ethernet interface should only be used once, as a master or backup. Do not re-use interfaces across a vinterface!
- advertisement-timer-value - Specifies how often the master VRRP interface advertises itself to other interfaces in the pool. Do not change this value unless instructed to do so by technical support.
- heartbeat-timer-value - Sets the basis of the value used by the Acme Packet Net-Net OS-E and Net-Net 2600 to determine how long to wait before failing over to the backup interface. Do not change this value unless instructed to do so by technical support.
- ip - Configures parameters of IP on a VRRP interface.
- Vlan - Creates or edits a VLAN on a VRRP interface.
