Some notes on trunking with Foundry routers/switches

  • trunks can be 2, 4, or 8 ports
  • trunk ports must be in the same VLAN
  • trunks must be ports 1-2, 1-4, 1-8,
  • trunks can span gig modules, but still need at least two ports on each module: (e.g 1/1 - 1/2 and 2/1 - 2/2)
  • the router must be rebooted to enable and/or disable trunks
