I'm currently setting up a bunch of LAGs on a GS724, this branches off to 3x GS748s, and I want to give as much bandwidth to each as I can.
I've inherrited these units and this kind of setup is new to me, but I'm not daft. The difficulty I have is; the firmware version on the 24 and the 48s is vastly different. At present the 24 is running v4.2.1, the 48s are running v3.1.4. On the download pages I see v5.x.x is available for the 24 port, but v3.1 is the latest listed for the 48s.
Is this correct? Should all of these switches run the v5 firmware? I really want them all running the same for obvious reasons, but I don't want to shag them up!!
The trunk setup is so easy with the 24 port, with the 48 it all seems backwards and I'm unable to get any lag lines setup, everything I try loops and bombs the network.
The latest firmware version for the GS748Tv3 is v3.1.4 while the latest firmware version for the GS724Tv3 is v5.4.2.30.
For the GS724Tv3, I suggest you to upgrade the firmware in a ladderized manner. First, upgrade the firmware from v4.2.1 to v4.2.1.5. Then, from v4.2.1.5 to v4.2.1.8 and so on until you reach the latest firmware version which is v5.4.2.30. Be sure to perform a factory reset on the the GS724Tv3 switch/es after upgrading to the latest version then reconfigure the settings from scratch in order to start clean using the latest firmware version.
You may want to take screenshots of the settings configured on the GS724Tv3 switch/es before you proceed with upgrading the firmware. It is because the config file you saved from firmware v4.2.1.x will not be restored once the firmware has been upgraded to v5.x.x.x. You can download the firmware versions for the GS724Tv3 switch here.
