When you see any reference related to CatOS, it pertains to an old operating system supported on Catalyst switches. The commands and syntax under that operating system are very different than a regular Cisco IOS router.
Cisco decided to unified the commands and syntax across platforms and Catalyst switch IOS was created. If you know regular Cisco router IOS, you can quickly configure a Catalyst switch running IOS without going through the learning curve. You will find some limitation on commands in switches but they are mostly due to hardware constraint.
Just to add to Edison's information, some of the chassis switches could run both Cat OS and IOS, at the same time. Cat OS controlled the L2 switch features, IOS controlled the L3 features. This existed for the reason that the L3 hardware was often an option on the chassis supervisor and so it ran its own code. At least on the 6500 series, this became known as hybrid mode. Later IOS images, on such platforms, supported both L2 and L3 directly, and became known as native mode.
Question We run asr9001 with XR 6.1.3, and we have a very long delay to
login w/ SSH 1 or 2 to the device compare to IOS device. After
investigation, the there is 1s delay between the client KEXDH_INIT and
the server (XR) KEXDH_REPLY. After debug ssh serv...
Introduction The purpose of this document is to demonstrate the Open
Shortest Path First (OSPF) behavior when the V-bit (Virtual-link bit) is
present in a non-backbone area. The V-bit is signaled in Type-1 LSA only
if the router is the endpoint of one or ...
Hi, I am seeing quite a few issues with patch install and wanted to
share my experience and workaround to this. Login to admin via CLI, then
access root with the “shell” command Issue “df –h” and you’ll probably
