The toggling stops as soon as one WAN bridge isĪssigned an IP address through DHCP. Requests on any one of the WAN bridges at a time, for 30 second intervals. NFVIS toggles between the two default WAN bridges sending DHCP During system initializationĪ second WAN bridge is configured with GE0-1 port attached. In zero touch deployment, NFVIS requests for IPv4 assignments through DHCP for two WAN interfaces.

This feature is supported only on ENCS 5000 series devices. If wan2-br is DHCP enabled WAN bridge, you must remove DHCP from wan2-br to apply default IPv6 is not supported for dual WAN toggle. Through the other WAN bridge is established only if static IP is applied to the second WAN bridge and static routing is configured In case connectivity fails on the WAN bridge with DHCP configurations, connectivity NFVIS does not detect connectivity failure from one WAN bridgeĪnd switchover to another WAN bridge. It is only triggeredĭuring fresh installation of NFVIS or after a factory default reset.Īctive/standby or redundant WAN bridges are not supported.

The DHCP toggle behavior is not supported during the upgrade flow. IP address through one WAN bridge, the other WAN bridge can beĬonfigured with static IP address for connectivity to NFVIS. Network is down on one of the WAN bridges.
This allowsĬonnectivity to NFVIS during initial deployment even if the With DHCP by default is supported on ENCS 5000 series platform.ĭuring NFVIS system initialization, NFVIS attempts to establishĬonnectivity through DHCP on both WAN bridges. Starting from NFVIS 3.10.1 release, a second WAN bridge configured Must begin with a letter or digit and can contain alphabets, numbers and hyphen.ĭual WAN support provides multiple links to NFVIS connectivity. Must contain minimum length of 2 and maximum length of 255. You must adhere to the following rules for hostname on NFVIS: The additional memory required for DPDK support is counted per NUMA node available on the system. System memory is allocated on socket 0 on system with multiple CPU sockets. Starting from NFVIS 4.2 release, all memory apart from the amount reserved for system is converted to HugePage memory. In case of other systems, the memoryĪllocation remains the same that is reserved for NFVIS Release 4.2.2 till NFVIS 4.8.1Īdditional memory required for DPDK support per NUMA node * indicates that the memory allocation is applicable only for Multi-NUMA node systems. Reserved for NFVIS 4.9.1 and later releases Reserved for NFVIS 4.2.2 till NFVIS 4.8.1 Reserved for NFVIS 3.12.x and 4.1.x releases Reserved for NFVIS 3.12.x and earlier releases If hyper-threading is enabled on the device, each core reflects two logical CPUs. NFVIS 3.12.x and later Releases with DPDK support
The following resources are required for a standalone Cisco Enterprise NFVIS: Table 2. The VMs are deployed using hugepage memory even when DPDK is enabled on the system. The system memory allocations are enhanced and all memory apart from the amount reserved for system is converted to HugePage
