Provides guidelines and limitations for configuring FPGA profiles on switches. These requirements ensure proper feature support and system stability during upgrades and configuration changes.
-
Configure the FPGA Profile globally on the switch. All base system and expansion modules use the same FPGA Profile. If your switch has an expansion module, the profile applies to it as well.
-
You must reload the switch after changing the configured FPGA Profile to activate the profile.
-
FPGA Profile is supported in Cisco IOS XE release 17.8 and later. If you upgrade from an earlier release that does not support FPGA Profile, such as Cisco IOS XE 17.7.1, the system installs the default FPGA Profile. Any FPGA Profile-controlled features that you configured in the earlier release and that the default profile does not include will be rejected.
-
CTS IPv6 is not supported in the default profile, so CTS IPv6 configurations are rejected during bootup after the upgrade.
-
After a Cisco IOS XE upgrade where the cts-ipv6 profile is loaded, existing PRP and DLR configurations are rejected upon bootup.
-
To keep the existing profile and feature configurations after an upgrade, select the required FPGA Profile after booting the switch. Refer to the procedure in Configure an FPGA profile.
-
Do not copy running-config to startup-config or write memory.
-
Reload the switch to ensure the required feature configurations are not discarded.
