Need Help Supervisor Replacement in Quad-Sup 6T VSS 6807

[jacob.fredriksson]

Hello!

I am trying to find out how to replace a failed Supervisor in a Quad-Sup 6T (the latest sup) VSS in 6807 chassis. I am only able to find documentation on how to replace a failed supervisor in Quad-Sup 2T VSS in 6500 chassis but I don't think the same procedure applies to the 6807 model.

For the 6500 models there seems to be 2 ways on doing the replacement; either insert up the new supervisor in a seperate empty chassi to boot it and upload the matching Software image or it won't join the VSS once it is installed in the production chassi. I guess this would also work on the for the Sup 6T but we don't have an empty 6807 chassi around for these kinds of things... seems very odd to me.

The other method is to physically move the CompactFlash from the broken supervisor to the new supervisor in order for it to get the matching Software version. (see http://www.cisco.com/c/en/us/support/docs/switches/catalyst-6500-virtual-switching-system-1440/117850-config-quadsupvss-00.html#anc3)

But I cannot find any documentation for how do to this on the 6807 chassi. It does not have a removable CompactFlash to store the boot images as far as I know. According to the datasheet the 6807 uses Internal Enhanced USB (eUSB) to store the boot image etc. (see http://www.cisco.com/c/en/us/products/collateral/switches/catalyst-6500-series-switches/white-paper-c11-737405.html#_Toc453974621)

Any help is much appreciated,

Thanks in advance

Hi Reza!

I have some answers for your questions:

Answer #1: I have now tested inserting a USB-stick into the 6T supervisor USB-slot and copying image between the supervisor bootdisk and the USB-stick works!

The supervisor recognized my Kingston DataTraveler 2 GB USB-stick. It is formated in the FAT32 file system.

This is the display output when the USB-stick is inserted:

Dec 15 14:21:08.765 CET: %USBFLASH-SW1-5-CHANGE: disk0 has been inserted!
Dec 15 14:21:08.765 CET: %USBFLASH-SW1-5-CHANGE: disk0 Initialization in progress. Do not remove until initialization complete.
Dec 15 14:21:10.437 CET: %CONST_DIAG-SW1-6-DONOT_REMOVE_DISK: Please do not remove disk0:, since Online-Diag is ready to test it, TestCFRW is estimated to finish after 60 seconds.
Dec 15 14:21:11.453 CET: %USBFLASH-SW1-5-CHANGE: disk0 Initialization complete.
Dec 15 14:21:31.254 CET: %DIAG-SW1-6-TEST_RUNNING: Switch 1 Module 3: Running TestCFRW{ID=42} ...
Dec 15 14:21:33.255 CET: %DIAG-SW1-6-TEST_OK: Switch 1 Module 3: TestCFRW{ID=42} has completed successfully

The USB-stick is assigned disk0:

I can check the content of the USB-stick (I had some files on it):

CSW01# dir disk0:

Directory of disk0:/
2285 drw- 0 Apr 12 2016 11:03:28 +02:00 IPERF
2305 drw- 0 Dec 28 2015 13:36:46 +01:00 USB Serial Drivers
2572 drw- 0 Dec 4 2015 12:22:20 +01:00 WiFi Scanner

If inserted the USB-stick into a standby supervisor it will be assigned ics-disk0:

It was possible to copy files between bootdisk: and disk0:

If I remove the USB-stick the following message will be displayed:

Dec 15 14:23:07.783 CET: %USBFLASH-SW1-5-CHANGE: disk0 has been removed!

Answer #2: Yes, the interface MGMT0 can be used for transferring files. I can set an IP-adress and connect my PC to it. 

Answer #3: Interface MGMT0 does NOT have the command ip vrf forwarding. It is a routed-only port, I cannot use the switchport command to change it to a switchport.

Thanks for feedback Jacob!

It stands for "Compact Flash".
