Please refer to the Topology section for more information about feature and functions of the Topology Dashboard.


Note: UNUM automatically creates a default collector titled netvisor-collector-fabricname when the Fabric is created. View and manage the Collector selecting Manager → Manage Collector. A Syslog entry is also created at the same time. View and manage the Syslog selecting Manager → Security/Monitoring → Manage Syslogs.

Super Fabrics


A Super Fabric expands the maximum number of switches from 32 to 140 using four pods. We use the concept of Pods, with each pod containing up to a maximum of 32 switches.


Refer to the EVPN - Symmetric IRB & Super Fabrics Use Case for detailed information on the use of EVPN.


Concepts and Terminology Used in Super Fabrics


Terminology


Local – A subnet is deemed Local to a POD if it’s only configured on that POD.

Remote – A subnet is deemed Remote if it’s not LOCAL on that POD.

Stretched – A subnet is deemed Stretched if it’s present on two or more PODs.

IRB – Integrated Routing and Bridging

EVPNVXLAN Ethernet VPN

VRF – Virtual Routing and Forwarding

VNI – VXLAN Network Identifier 


Create a Super Fabric


To create a Super Fabric, drag and drop a Seed Switch for each pod on to the planning surface.
