Due to chip supply constraints, Juniper has had to swap the PoE controller chip in some of their switches.
The different chip requires different firmware.
Today’s post concerns temperature thresholds for telecom facilities, and the rabbit hole I discovered when figuring out how to monitor temperature of Juniper equipment.
There are likely going to be other reasons why you may get an error upon committing a config such as:
CommitError(edit_path: DCD commit check failed, bad_element: None, message: error: DCD commit check process dumped core error: configuration check-out failed)
or
dcd[16947]: ../../../../../../src/junos/sbin/dcd/infra/db-param/param_access.c:dcd_param_set_iff_ptr_value:2248: insist ‘len <= iff_obj_maxlen[param_ix]’ failed
but here's one that I encountered and found a fix for.
ERSPAN is a great way to remotely troubleshoot a wired connection remotely. Even before the work-from-home era, I dreaded having to head out to a location, setup a mirror port, and connect a laptop to grab a few packets. The process of getting to the location often took longer than solving the actual issue…
DHCP Security (or Snooping) is critical in a campus environment. Unfortunately, deploying it correctly always seems to have a snag.
Have you ever come across something like CHASSISD_UI_POE_ERR: PoE port name mge-0/0/45 status 61 and wondered what the heck “status 61” means? Let’s find out!
Using a LTE as the primary WAN link for a Juniper SRX. Also, wrestling with Verizon provisioning.
Sure, you could try and follow Juniper’s instructions, but these ones are way easier!
As I install/upgrade a ton of new Juniper EX3400-48P edge switches in VCs, I’ve run into a few issues where upgrading Junos and then the PoE controller firmware results in the PoE Controller failing.
