13. Set the VLAN tag on each server canister. If this document is used, the tag must be 101.
# Set tag
/bin/ipmitool lan set 1 vlan id 101
# Confirm tag
/bin/ipmitool lan print 1 | grep -i 'VLAN ID'
Non-IBM Cumulus switches
If you have a non-IBM Cumulus switch, use the information above as a general reference on how to
modify the switch. The key is to have a designated IBM Elastic Storage System 3200 trunk ports that are
apart of both VLANs.
Modifying existing Cumulus switches
If you are converting a switch that has already non-ESS 3200 using the switch on any port in the range 1 -
12, you need to evacuate one by one those ports. If you are not using ports in the range 1 - 12, you need
to apply the above process.
That means to move the cables on the upper ports in the range 1 - 12 to any free upper port that is not in
the range ports 1 - 12. Equally any lower cable plugged to any port in the range 1 - 12 needs to be moved
to any lower port not in the range of ports 1 - 12.
You must move one cable at the time and wait until the link LED on the destination port comes up. Once
all ports in the range 1-12 are no longer cabled, you can apply the following procedure.
If an existing Cumulus switch must be modified to support IBM Elastic Storage System 3200, the general
guidance are as follows:
1. Free up at least two ports (1 IBM Elastic Storage System 3200) on the existing switch. It is better if you
can free up a block. Ideally, the current configuration is not scattered where it is easy to convert free
ports for IBM Elastic Storage System 3200 usage.
2. Take the existing interfaces file from the switch and modify it for the chosen IBM Elastic Storage
System 3200 ports.
3. Make the modifications to the interfaces file.
auto swp10
iface swp10
bridge-pvid 102
bridge-vids 101
Any ports that you designate as IBM Elastic Storage System 3200 ports need to have this
configuration. Consult the default IBM Elastic Storage System 3200 interfaces file for more
information.
4. Copy the new interfaces file to the switch.
5. Reload and verify the interfaces.
6. Set the VLAN tags on the IBM Elastic Storage System 3200 canisters.
