LLT marks a high-pri link of a peer node as “troubled”, if it does not receive any packet on that link for this timer interval. Once a link is marked as “troubled”, LLT will not send any data on that link till the link is up.
- In some circumstances, when the private networks links are very slow or nodes in the cluster are very busy, increase the value.
- Increase the value for planned replacement of faulty network cable /faulty switch.
To increase the value of peertrouble run:
# lltconfig -T peertrouble:350
(3,5 sec, The default LLT peertrouble time is 2s for hi-pri links and 4s for lo-pri links.)
# cat /etc/llttab set-node b0d06u02 set-cluster 91 link ce1 /dev/ce:1 - ether - - link ce6 /dev/ce:6 - ether - - link-lowpri ce0 /dev/ce:0 - ether - - set-timer peertrouble:350 exclude 2-31
