Notes

	nv set interface <interface-id> link ib-subnet <subnet-name> nv unset interface <interface-id> link ib-subnet Assigns an IB interface to the specified subnet (SWID). The unset for of the command resets the interface to the default subnet (infiniband-default).
Syntax Description	interface-id	The IB interface name or range of IB interfaces
	subnet-name	The target subnet name: infiniband-default, infiniband-1…infiniband-3
Default	infiniband-default

Example	Copy Copied! `admin@nvos:~$ nv set interface sw3-4p1-2 link ib-subnet infiniband-1 admin@nvos:~$ nv config apply -y Warning: IB interface configuration is changed. In order to apply configuration the port will be restarted. Warning: IB subnet configuration is changed. The following ports will be temporarily brought down during the change: sw3p1,sw3p2`

Related Commands	nv show interface nv show interface link
Notes	Supported for IB ports only. FNM ports do not support ib-subnet configuration. When changing the subnet of an interface, the other port on the same transceiver will be temporarily brought down, even if its subnet is not changing. For example, changing the subnet of `sw1p1` will cause `sw1p2` to be temporarily restarted.

	nv show ib router routing-table Displays the IB routing table with one entry per subnet, showing the subnet name, subnet prefix, and validity status.
Syntax Description	N/A
Default	N/A
History	25.02.7002
Example	Copy Copied! `admin@nvos:~$ nv show ib router routing-table IB Subnet Subnet Prefix Valid ------------------ ------------- ----- infiniband-default 1 true infiniband-1 2 true infiniband-2 0 false infiniband-3 0 false`
Related Commands	nv change system profile ib-routing num-of-swids nv set interface link ib-subnet
Notes	For an entry to be valid, at least one port must be assigned to the subnet and in UP state, and a correctly configured SM must be running on that subnet. Valid `true` indicates the routing entry is active and traffic can be routed to/from this subnet.
