Unified ISSU FPC Support on T4000 Routers

In the FPCs on T4000 routers, interface-specific and firewall filter statistics are preserved
across a unified ISSU. During the unified ISSU, counter and policer operations are disabled.
To preserve statistics across a unified ISSU on T4000 routers with FPC/PIC interfaces,
the router stores the statistics data as binary large objects. The router collects the
statistics before the unified ISSU is initialized, and restores the statistics after the unified
ISSU completes. No statistics are collected during the unified ISSU process.
To verify that statistics are preserved across the unified ISSU, you can issue CLI operational
commands such as
show interfaces statistics
Unified ISSU is supported on the following FPCs:
T4000 FPC5 (model numbers—T4000-FPC5-3D and T4000-FPC5-LSR)
Enhanced Scaling FPC4-1P (model number—T640-FPC4-1P-ES)
Enhanced Scaling FPC4 (T1600-FPC4-ES)
Enhanced Scaling FPC3 (T640-FPC3-ES)
Enhanced Scaling FPC2 (T640-FPC2-ES)
NOTE: The aforementioned FPCs are also supported on TX Matrix Plus routers
with 3D SIBs.

Unified ISSU Support on MX Series 3D Universal Edge Routers

The following sections list the Dense Port Concentrators (DPCs), Flexible PIC
Concentrators (FPCs), Modular Port Concentrators (MPCs), and Modular Interface Cards
(MICs) that are supported during a unified ISSU on MX Series routers.
