Hi, It is better to have them in port channels so that it has a path to the other switch if one fails.
Sorry if this is a dumb question  - Pair of Dell S4048-ON's running VLT/VRRP have a bunch of switches dual homed. Do I still need to run port channels  for multiple vlans ? S4048-A Te1/6 - N1524 Te1/0/1 S4048-B Te1/6 - N1524 Te1/0/2  So need to send vlans 31,32,100,128,200   Do I just tag the interfaces or create port channels ?   Ta Scott
