Previously, Aruba switches could lose the host label cmk/device_type:switch
after a firmware upgrade. Newer firmware reports the device type in the SNMP
system description (.1.3.6.1.2.1.1.1.0) in an abbreviated form such as "Swch"
instead of the full word "Switch". Because the label was derived by searching
for the literal word "Switch", it was no longer set once host label discovery
ran against the new system description.
Device type detection now also recognizes the abbreviated form, so affected
Aruba switches are labeled cmk/device_type:switch again. Detection for the
previous, non-abbreviated system descriptions is unchanged.
To restore the label on already-monitored hosts, re-run the host label discovery for the affected switches.
