PowerConnect 6248 https certificate serial number issue

Question

Hi, We have two PowerConnect 6248 switches running firmware version 3.2.0.7. We've generated a certificate for each of them and enabled the HTTPS management interface on them with the following commands:   crypto certificate 1 generate ... ip https server   We can now manage the first switch via HTTPS with Firefox with no problems, but when trying to access the second switch, Firefox will stop with the following error message:   Your certificate contains the same serial number as another certificate issued by the certificate authority.  Please get a new certificate containing a unique serial number. (Error code: sec_error_reused_issuer_and_serial) Indeed both certificates appear to have a serial number of 1. How do we regenerate one of the two certificates with a different serial number? Thanks.

Use the following on one switch: console#configure console(config)#ip https certificate 1 And this on the other: console#configure console(config)#ip https certificate 2

Thanks for the reply, it looks like I'll have to generate certificate 2 on one switch, before I can assign it to the HTTPS management interface.

But what if we get a 3rd PowerConnect switch (which we may at some point)? Since each switch can only have two certificates, how do we avoid the conflicting serial number issue?

Thanks.

I have 4 Dell PowerConnect 6224's and have just run into the proposed problem. Any fix?
