I thought the last change date would get reset to 0 days when the SSA is reset or rebooted. Therefore you would never see a last change date further out than the uptime date.<BR /> thnks in advance<BR /> walt<BR /> Wed, 27 Jan 2016 01:53:00 GMT Walt_Witkowski 2016-01-27T01:53:00Z https://community.extremenetworks.com/t5/extremeswitching-eos/uptime-of-switch-shorter-than-last-change/m-p/17013#M424 SSA ver 07.71.02.0005 SSA uptime shows 188 days but it also shows ports with a last change of 435 days or 343 days as an example.

Rollover for this value is something like 497 days. A lengthy uptime could result in the scenario you describe. <BR /> <BR /> Regards,<BR /> Mike Thu, 28 Jan 2016 00:30:00 GMT https://community.extremenetworks.com/t5/extremeswitching-eos/uptime-of-switch-shorter-than-last-change/m-p/17014#M425 Mike_D 2016-01-28T00:30:00Z
