Users Guide

Layer 3 VXLAN network is a VXLAN type of network that contains a list of IP addresses and an anycast IP address. Optionally,
DHCP relay addresses can also be specified. Layer 3 VXLAN network can be configured over a leaf node. Layer 3 VXLAN
network can be attached to an uplink. Each VLTi uplink interface contains an IP address that is allocated from the list of IP
addresses that are configured on the layer 3 VXLAN network.
Static routing policies
A static route is a route policy template that contains a network prefix and the next hop IP address. This policy can be attached
to one or more nodes in the fabric. When this policy is attached to the node, a static route with the specified prefix and next
hop IP address is configured in the node.
eBGP peering policies
An eBGP peering policy is a routing policy template that contains BGP remote addresses and the remote AS number. A remote
address can be an interface address or a loopback address. This policy can be attached to one or more nodes in a fabric. When
this policy is attached to the node, a BGP session is associated with the switch.
Uplink bonding options
Following are the options using which uplink bonding can be achieved:
● LACP
● Static bonding
● No bonding type configured
● Spanningtree considerations
LACP
In LACP uplink bonding, SmartFabric services wait for LACP PDUs from the remote device to configure the LACP LAG for the
uplink. Networks that are attached to the uplink are associated with the LACP LAG that is created.
Static bonding
In static bonding, SmartFabric services configure a static LAG for the uplink and the networks that are attached on the uplink
are associated with the LAG that is created.
No bonding type configured
When no bonding type is configured, network is attached to the uplink physical interface. This configuration is used specifically
by layer 3 routed uplinks.
Spanning tree considerations
For VXLAN networks, the network must be loop free. SFS does not allow configuration of the same network on multiple uplinks
to ensure that no loops are created accidentally.
For Layer 3 VLAN networks, RPVST+ is enabled on the uplink interfaces by default. It is recommended not to change the
spanning tree type or to disable it.
NOTE:
Configuration of an Ethernet – No STP uplink with members from only one switch in the SmartFabric is not
supported. It is required to have member ports from both switches in the SmartFabric.
Dynamic onboarding for integrated devices
SFS discovers and onboards the following vendor end-host devices based on specific custom originator TLVs in LLDP PDUs
sent out through the connected ports.
● iDRAC
● Isilon
● VxRail
● Trident
● VxFlex
When a new server interface is detected in an attached port, the new configuration is applied.
