Yesterday I had an issue with a customers new Juniper 2200 48-port POE switch.
The configuration we had set included this:
poe {
interface all;
}
This was the default configuration. However, this apparently only put POE on the first 24 of the 48 ports and set ports 25-48 as “low priority”. Consequently, they were not getting POE on these ports.
JTAC examined the configuration and added this command to enable high priority on all ports for POE:
root@# set poe management class interface all
This seemed to resolve the problem
