You are ready to prepare the EPLD images for Installation (see the “Preparing the EPLD Images for
Installation” section on page 8-44).
EPLD Images Needed for vPCs
The virtual port channel (vPC) feature is available beginning with Cisco NX-OS Release 4.1(3). When
you enable vPC on the chassis, you must have EPLD image 186.3 (or later image) on the 32-port
10-Gigabit Ethernet types of I/O modules (N7K-M132XP-12 and N7K-M132XP-12L).
Note The EPLD upgrade operation is a disruptive operation. You should execute this operation only at a
programmed maintenance time. The system/kickstart ISSU upgrade is a nondisruptive upgrade.
Most of the N7K-M132XP-12 modules in the chassis already meet this minimum EPLD requirement,
but if you are working with an N7K-M132XP-12 module that was shipped before June 2008, you might
need to upgrade the EPLD version.
To determine the EPLD version for all N7K-M132XP-12 modules, enter the show version module
slot_number epld command. If the line FE Bridge(x) version displays a version earlier than 186.7, you
should schedule an EPLD upgrade to a version that is compatible with the target Cisco NX-OS release.
For example, if you want to run Cisco NX-OS Release 6.1(1), you should choose Release 6.1(1) EPLDs.
