Note: A product listed in this article has either reached hardware End of Life (EOL) OR software End of Engineering (EOE). Refer to End of Life Products & Milestones for the EOL, EOE, and End of Support (EOS) dates.
This article explains how to swap interfaces back to their expected configurations.
Note : This issue affects STRM 5000 II and NEBS appliances as well as the JSA 1500 [juniper.net] and 3500.
Ethernet interfaces were swapped. For versions 2012.2R3 and earlier, please see the following Knowledge Base article instead: KB17314 - [STRM/JSA] Interfaces are swapped [juniper.net]
After the device reboots, you will most likely see something like this scroll past:

1. Edit /etc/udev/rules.d/70-persistent-net.rules and correct as shown in the following configuration.
/etc/udev/rules.d/70-persistent-net.rules
2. Replace the MAC addresses with the corresponding values from the output above.
