Description
- Currently, the supported range of msgTxInterval is 5 - 32768 sec.
This does not comply with the LLDP specification which states 1 - 3600 sec. See IEEE Std 802.1AB™-2016, section "9.2.5.7 msgTxInterval".
The LLDP stack shall at least support a minimum TX interval of 1 second.
The maximum interval shall be kept at 32768 seconds so that existing devices are not forced to change their behavior.
-
Currently, the supported range of msgTxHold is 2 - 10.
This does not comply with the LLDP specification which states 1 - 100. See IEEE Std 802.1AB™-2016, section "9.2.5.6 msgTxHold".
- In addition it was found that a change of msgTxInterval and/or msgTxHold does not have an immediate affect when observing the behavior on the network.
Example:
When changing msgTxInterval from 3600 seconds to 1 second, it is expected that right after setting the new value, the LLDP stack will start sending LLDP frame with a 1 second interval.
Currently, the LLDP stack applies the new value not before the TX_TIMER expires. This means that in the worst case it takes up to 3600 seconds until the new interval of 1 second gets applied.
This shall be changed so that the new value is applied right away by taking LLDP's "localChange" variable into account (see IEEE Std 802.1AB™-2016, section "9.2.5.3 localChange").
