Hi All, FYI I raised a TAC case and a very helpful engineer asked me to run "fsck bootdisk:" which fixed the issue immediately - I don't think I've used that command for 15 or 20 years on a Cisco switch or router! Anyway, thanks for your replies, all sorted now.

Thanks for the replies.
I'm trying to copy the image onto the active bootdisk: and it doesn't matter what method I try, from a TFTP server, an FTP server or from the slavebootdisk: I always get the same error message on the active supervisor, e.g.

I can copy to the standby supervisor without an issue.
I could accept that the bootdisk: was indeed corrupt if it was a one off but this is affecting all my enterprise production switches (16) which is why I suspect it's something else. The switches are geographically dispersed so the SD or USB option would be very time consuming.

Hi,
I'm trying to upgrade our production 6509 supervisor 2T 10GE switches from version 15.1(1)SY4 to 15.2(1)SY5. I can copy the image to the slave supervisor with no problem but when I try to copy to the active supervisor I get the following error message:
"%Error opening bootdisk:/s2t54-ipservicesk9-mz.SPA.152-1.SY5.bin (Directory entries are corrupted, please format the disk)"
I'm having the problem with all our production switches and can't copy using TFTP, FTP or from the slavebootdisk: I'm guessing forcing a redundancy switch-over will fix the issue (haven't tried yet) but I'd rather avoid doing this. Has anyone else had this issue and know of a fix or workaround?
Thanks,
Graham

Hope you don't mind me jumping in on this thread. When you say " Upgrade and reboot the primary switch first "do you mean the configured primary or the operational primary? I have some Nexus switches (albeit N7ks) that are as follows:
vPC role : primary, operational secondary
Which one should I upgrade first?
Thanks

Hi, I’ve been doing some research into implementing storm control across an enterprise network and have come across some excellent articles. One comment to an article stated (paraphrased): “1) One very important remark everybody seems to miss, is that storm-control only works on INBOUND packets. It does not prevent a port from being overwhelmed with broadcasts from the core or distribution. [assuming only configured on access ports] 2) Watch out with storm control on trunk ports! What is a broadcast on a trunk? In any "allowed-vlan"? No, any broadcast in any vlan, even non-allowed. 2b) The storm-control "drop filter" action will block on all VLANS.” Please could someone confirm whether this is true and point me in the direction of any Cisco documentation that details this behaviour? I ask because I’m concerned that a broadcast storm on one VLAN could cause broadcast traffic to be dropped on a completely unrelated trunk. TIA

Thanks Karsten and thanks for pointing me to the Q&A - relevant section pasted below in case someone else stumbles across this thread:
Q. How many Cisco StackPower stacks can be built within one data stack? A. In theory, one switch is a stack on its own in terms of Cisco StackWise. In terms of Cisco StackPower, one switch constitutes a StackPower stack of one switch. The recommendation is to have Cisco StackPower stacks of four switch members to maximize the effect of power aggregation and redundancy. Another option is to build three Cisco StackPower stacks of three each, for a total of nine switches, matching the maximum number of switch members in a Cisco StackWise stack (also known as a data stack).

Hi, I know from the documentation that it's only possible to connect a maximum of four switches in a stack power configuration. I need to have five switches in a data stack, is it possible to configure three switches in one stack power and the other two switches in a separate stack power or will I have to have four switches with stack power and the fifth stand-alone? Hope this makes sense.
Thanks,
Graham

I know it's been a while but I wondered if you resolved your duplicate IP address problem. If not have a look here http://www.cisco.com/c/en/us/support/docs/ip/address-resolution-protocol-arp/118630-technote-ipdt-00.html and here http://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/8021x/116529-problemsolution-product-00.html
I managed to solve the issue with “ ip device tracking probe use-svi”

Thank you, that's what I thought. Now to figure out why it's showing 100% via SNMP. Edit. I've just tried that command on the CFC equiped modules and it seems to work, the output is a bit worrying though! router#remote command module 2 sh proc cpu sort CPU utilization for five seconds: 93%/92%; one minute: 97%; five minutes: 98% router#remote command module 8 sh proc cpu sort CPU utilization for five seconds: 99%/97%; one minute: 98%; five minutes: 98% router#remote command module 9 sh proc cpu sort PU utilization for five seconds: 99%/96%; one minute: 98%; five minutes: 98% The DFC modules look fine.

Hi, Is it possible to view the utilisation of individual CFC CPUs on 6500/7600 line cards via CLI? We have an SNMP based management solution that is reporting 100% CPU utilisation on a couple of ethernet modules with CFC daughter cards in a 7609 chassis but can't see any CLI commands that might verify. Thanks
