■
In the ethernet-switching-options configuration, if action is not configured for the
number of MAC addresses allowed on the interface (under secure-access-port
interface interface-name mac-limit in the CLI or in the Port Security Configuration
page in the J-Web interface), and you try to commit the configuration, the commit
will fail. You must configure an action for the MAC address limit before upgrading
from Release 9.2 to Release 10.1.
■ If you have configured a tagged interface on logical interface 0 (unit 0), configure
a tagged interface on a logical interface other than unit 0 before upgrading from
Release 9.2 to Release 10.1. If you have not done this and you try to commit
the configuration, the commit will fail. Beginning with JUNOS Release 9.3 for EX
Series switches, untagged packets, BPDUs (such as in LACP and STP), and
priority-tagged packets are processed on logical interface 0 and not on logical
interface 32767. In addition, if you have not configured any untagged interfaces,
the switch creates a default logical interface 0.
■ On EX4200 switches, if you have installed advanced licenses for features such
as BGP, rename the /config/license directory to /config/.license_priv before
upgrading from Release 9.2 to Release 9.3 or later. If the switch does not have
a /config/license directory, create the /config/.license_priv directory manually
before you upgrade. If you do not rename the /config/license directory or create
the /config/.license_priv directory manually, the licenses installed will be deleted
after you upgrade from Release 9.2 to Release 9.3 or later.
Downgrading from JUNOS Release 10.1 to Release 9.2 for EX4200
Switches
When you downgrade a Virtual Chassis configuration from JUNOS Release 10.1 to
Release 9.2 for EX Series switches, member switches might not retain the mastership
priorities that had been configured previously. To restore the previously configured
mastership priorities, commit the configuration by issuing the commit command.
