Limitations of Simple Ring Topology
•
If one of the satellite in a simple ring setup is removed from the ICL configuration, the subtending
satellites remain in the connected state.
•
When the configuration for a new satellite is applied, then the existing conflicting nV configuration must
be removed.
•
In a simple ring or a dual head topology, the local Layer-2 xconnects having satellite interfaces from
active and standby satellites are not supported. All the satellites part of the local xconnect have to be in
active state.
•
Bundle ICL interfaces are not supported in the Simple Ring topology, but sat-ether port bundle is
supported.
•
When you activate a new image on the satellite in a simple ring topology based network, you need to
initiate install transfer followed by an install activate. For more information, see Installing a Satellite.
•
Satellite access bundles with bundles members spanning across different satellites are not supported.
For example, if there are three satellites, namely, sat 100, sat200, and sat 300, then you cannot have an
access bundle with members from sat 100, sat 200 and sat 300. This is because each of the satellite could
be active/standby to different hosts and hence leads to unpredictability in their behavior.
Layer 2 Fabric Network Architecture
In the Layer 2 Fabric network architecture, a satellite is connected to one or two hosts through one of two
Ethernet Virtual Circuits (EVC) of Layer 2 Fabric network. An EVC can be identified by two transports
VLAN IDs, such as TP-VID-S and TP-VID-H. TP-VID-S is the VLAN ID assigned by the satellite side
transport and TP-VID-H is the VLAN ID assigned by the host. The CFM based Fast Fabric Link Failure
Detection is supported only in the Layer 2 Fabric Network Architecture. The following illustrations show
different variants of Layer 2 Fabric network topology.
