I'm preparing to power-off and disconnect some old Cisco 3550-48 Ethernet
switches at a Customer site. For kicks, I jumped on the units and pulled the
output of sho ver one last time. I was shocked, and felt like I
had to erect some sort of memorial to the faithful service of these devices.
They (and the UPS devices that they're attached to) were installed in early December 2003 during an IP telephony migration. The switch in the maintenance garage (the first one) did well, certainly, but the switches in the wiring closet (the second two) performed beyond my wildest dreams. Looking back at my records, I'm not seeing that any trouble tickets were ever logged relating to these switches (bad ports, etc). They appear to be fully functional.
If you're familiar with Cisco IOS and the output of sho ver
then you'll know what's noteworthy about the output below.
(I know that this is silly, but for some reason I find this very touching.)
