We have some 3560 switches that have the ipbase image on them:
I need to upgrade to the k9 image so I can utilize ssh.
My question is regarding the image selection.
On the Cisco download page are two latest releases:
12.2.46-SE(ED) release in july 07
12.2.25-SEE(ED)release in aug 08
It always makes me nervous to jump trains, but I wonder if I am being too cautious.
The only items unique to the image currenlty in the switch are IPv6 stuff and "ISL VLAN" and support for 4096 VLAN ID (don't need).
I do have the router trunked to the switch and several vlans on the trunk, so I am thinking I need the ISL VLAN component.
What is the general rule of thumb for upgrading?
Should you always try to upgrade the the highest image, or stick the the image closest to what is in the switch at the time (even if it is almost two years old)?
