Cisco 4500 Switch Ios Download For Gns3 -

Power on the switch. Check the output:

show version
Cisco IOS Software, Linux Software (I86BI_LINUX_L2-ADVENTERPRISEK9-M), Experimental Version ...
ROM: Bootstrap program is Linux

It will not say "Catalyst 4500," but the CLI will support:

Congratulations. You are now running a 4500-class switching environment.

You cannot just boot a 4500 .bin file directly as a disk. GNS3 requires a bootloader or a combined image. A better method is using a QEMU image with IOS pre-installed. cisco 4500 switch ios download for gns3

Alternatively, use the IOL method (more reliable):

Let us assume you have obtained a legal L2 IOL image from Cisco CML. The filename is often something like: i86bi_linux_l2-adventerprisek9-ms.SSA.high_iron_20190423.bin

The 4500 image will hammer your CPU. After booting, right-click the switch → Idle-PC → Auto-calculate. This reduces CPU from 100% to ~5%. Power on the switch

Once you have your IOS image (e.g., c3745-adventerprisek9-mz.124-25d.bin), follow these steps to make it function as a switch.

By following these steps, you successfully simulate a Cisco 4500 environment for CCNP or CCIE lab practice without the need for physical hardware.

Unlike a Cisco 3725 router, you cannot just drop any .bin file into GNS3. The 4500 requires specific L2/L3 switching images that support the Layer 2 switching code GNS3 can partially interpret. It will not say "Catalyst 4500," but the CLI will support:

Warning: Many users search for a "switch image" but end up with a router image. A pure router IOS (like c7200-advipservicesk9) will not run switching commands (spanning-tree, vlan, port-security) on a 4500 platform in GNS3.
