    Upgrading Cisco Switch Firmware Slow

    I recently upgraded a Cisco 3560X switch. I upgraded from 12.2(53)SE2 to 15.0(2)SE8. I thought this would take 5 minutes max. After ten minutes I was worried. I connected a console cable and found the console reporting “Front-end Microcode IMG MGR: Programming device 0…rrrrrrwsssssssssssssssssssssspssssssssssssssssssssspsssssssss” Solution: After googling I have discovered it is quite normal to take up to 40 minutes due to an upgrade to the MCU (Micro Processing Unit).

    Cisco tdr command

    I recently discovered a really cool command on a Cisco 3560 switch. It has a TDR (Time-domain reflectometer). It basically means you can test how long the cable is, if it has a short, pair of wires open and any other problem. TDR works on 10/100/1000BaseTx. Fibre optic ports are not supported. TDR has been available after Cisco IOS Release 12.2(25)SE or later. This is a table of the different pair status results and their meanings. More info is available here from Cisco. Here is an example: Switch# test cable-diagnostics tdr interface g0/1 TDR test started on interface Gi0/1 A TDR test can take a few seconds to run on…
