⚠️ Do NOT attempt to load this on older Sup6 or Sup7 cards. It will not boot and could corrupt the bootflash.
: Maps the IOS XE release directly to its classic Cisco IOS equivalent version, which is Cisco IOS 15.2(7)E5 . This helps administrators reference compatible command syntaxes and legacy feature sets.
The software enables high-performance Layer 2-4 switching with several integrated services: cat4500es8-universalk9.spa.03.11.05.e.152-7.e5.bin
What does loading cat4500es8-universalk9.spa.03.11.05.e.152-7.e5.bin unlock on your switch?

When deploying this image, it is imperative to verify compatibility with your currently installed line cards. Supervisor Engine 8-E requires the use of E-Series line cards (such as the WS-X47xx family). Classic Catalyst 4500 line cards are generally not supported or are unsupported in tandem with newer architectures.
