I just found this a couple of days ago: http://docwiki.cisco.com/wiki/Cisco_NX-OS/IOS_Software_Default_Configuration_Differences Good summary about the default configuration differences between NX-OS and IOS. Lots of people are familiar with the settings in IOS but NX-OS is often a new experience. That document is one of the must-read documents for those who are migrating routing from good old […]

Cat6500 IOS Notes
According to SX SY ISSU Compatibility Matrix (http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/SX_SY_ISSU_Compatibility_Matrix.xlsx, link found for example in http://www.cisco.com/en/US/products/hw/switches/ps708/prod_release_notes_list.html), IOS 15.0(1)SY1 will be out still this year (or, they will decide about it this year…).

Cat6500 Sup2T CMP Note
I’ve had the Sup2T’s in the lab for a couple of days now. This is the time for trying out everything I want before deploying the system to production.

You need to reload the whole switch. Source: CSCsb07831 (Cisco login required) Apparently the standby supervisor will keep reloading if you try the switchover method, […]
IOS 12.2SX Software Releases – What to Use?
I’ve been thinking about Catalyst 6500 IOS upgrades lately. Those internal workhorses are usually not upgraded unless there are some specific reasons. Some of the Cat6500’s in my territory are running even 12.2(33)SXH releases, and SXH end-of-life announcement have already been made. That’s one reason for upgrading. One other reason is the need to get […]
Catalyst 6500 Sup2T Ethernet Module Compatibility
Many people think that Catalyst 6500 series is not actually very interesting anymore about 12 years after its introduction. However, the large installation base dictates that Cat6500 is not going to vanish any time soon. Cisco announced some new modules for Cat6500 last month. One of them is a supervisor module called Supervisor 2T (products […]
