I have to draw out a VLAN map for a bunch of Powerconnect 5448s that are used to connect 3 floors together. There are two fiber connections from teh top floor to the middle floor and then two fiber connections from the bottom floor to the middle floor. No VLANs or trunks. EVerything is one subnet. 1 switch on top floor. 4 switches on middle floor. 1 switch on bottom floor. The fiber connections only go to one switch on the middle floor.
It looks like the person who configured the switches created link aggregation groups on ports 47 and 48 on the 5448s on the top floor switch (LAG1), ports 47 and 48 on the bottom floor switch (LAG1), and then ports 45 and 46 (LAG1) and 47 and 48 (LAG2) on the middle floor switch that connects the other floors. Looking at the LAG membership page though on the Powerconnect web UI, there are only 48 ports that are options. The fiber ports are also labeled 45,46,47, and 48 on the switch itself.
My question is...
When someone creates an LAG for ports 47 and 48 on the 5448 and adds fiber connections to port 47 and 48, do the Ethernet ports 47 and 48 become unusable? Does the LAG on the two fiber ports now in essence become the 47 and 48 that were previously used by Ethernet?
