Reloading fabric switch

Note: The procedures in this section describe manual fabric switch configuration, which is only required if you have NPS deployed on your system, and Cloud Pak for Data System version is 1.0.7.3 or earlier. Starting with 1.0.7.4, this step is automated on NPS systems, provided that the NPS nodes are added to the BOM.

After all the files are updated, reload the interfaces.

Procedure

Run the following commands:

cumulus@fabsw1a:/etc/network/interfaces.d$ sudo ifreload -a 
cumulus@fabsw1a:/etc/network/interfaces.d$

There should be no output. If there is output about reserved VLAN being used: Cumulus reserves a range of VLANs for its own use. If a customer VLAN steps in this range, it is possible to move the range. The default range is 3000-3999. The minimum range is 300 VLANs. To avoid a range conflict, you can move either the front (3000) or the end (3999) to 3500. Run the following commands:

cumulus@fabsw1a:/etc/network/interfaces.d$ sudo sed -i '/resv_vlan_range/s/^#//' /etc/cumulus/switchd.conf 
cumulus@fabsw1a:/etc/network/interfaces.d$ sudo sed -i '/resv_vlan_range/s/3000/3500/' /etc/cumulus/switchd.conf 
cumulus@fabsw1a:/etc/network/interfaces.d$ grep resv_vlan_range /etc/cumulus/switchd.conf
resv_vlan_range = 3500-3999
cumulus@fabsw1a:/etc/network/interfaces.d$ sudo systemctl restart switchd
cumulus@fabsw1a:/etc/network/interfaces.d$ sudo ifreload -a
cumulus@fabsw1a:/etc/network/interfaces.d$

Then, run the commands from Step 1 again:

cumulus@fabsw1a:/etc/network/interfaces.d$ sudo ifreload -a 
cumulus@fabsw1a:/etc/network/interfaces.d$

Note: In an HA leaf pair, reload both interfaces as close together as possible.
