description |
The manpage for netplan doesn't indicate what the unit for mii-monitor-interval is on bond devices. It appears to be in whole seconds, but at the kernel level, the unit is milliseconds.
From my testing, it appears to be impossible to set a value for mii-monitor-interval with netplan that is <1s (e.g. I got a syntax error with a value of 0.1 for 100ms) |
[Impact]
Users of bond and bridges devices requiring tuning of the default device parameters.
[Test case]
== Configure MII monitor interval ==
1) Configure a bond device
2) Add parameters:
bonds:
mybond0:
parameters:
mii-monitor-interval: 1
3) Verify that the applied MII monitor interval is of 1ms, as opposed to 1 second (1000ms), by verifying the contents of /sys/class/net/mybond0/bonding/miimon
== Validate default behavior ==
1) Configure a bond device without parameters.
2) Verify that no special MII monitor interval is applied, the default value should be 0:
$ cat /sys/class/net/mybond0/bonding/miimon
0
[Regression potential]
MII monitor behavior is changing with this SRU. Default behavior for an unqualified value (ie. a number alone), which was also the only way to specify parameters, was to interpret the values as *seconds*. This leads to relatively slow checking of the device link status (for MII monitor), much slower than generally expected. The same applies to other time-based values such as up delay, down delay, arp interval. The interpretation for these values changes to reading them as *milliseconds* when unqualified, and a new way of qualifying the values (adding a modifier) was added. This was, people who do require "slow" checking of the MII link status will be migrated to "fast" checking right now, moving from an interval of 1 second to 1 millisecond (more checking means less false-negatives for packet passing through an interface, should reduce packet loss, at the cost of potentially flapping the interfaces (bringing down a path often if MII status is bad or slow to be returned)). Users who require the old behavior may add "s" at the end of the value to make it read as "1 second" again, or modify the value to be "1000", which will be 1000ms (1 second). We estimate the impact of this change to users to be minimal, actually requiring a 1 second interval for MII monitoring / up/down delay, and ARP interval is very uncommon and counter-intuitive as all other systems work on a millisecond basis.
