Once you make the physical connection you will need to configure the ports. If everything resides on one VLAN, then place the port in access mode for that VLAN. If there are multiple VLAN, then place the port in Trunk mode and include each VLAN. Example: console(config-if)# switchport mode access console(config-if)# switchport access vlan 2  or  console(config-if)# switchport mode trunk console(config-if)# switchport trunk allowed vlan add 2,3,4
I simply do not have enough 10G fibre ports on my core switch (AT x908) I have one left available port which connects to local PE 5548 (with 2 x FTLX8571D3BCL) But in remote building (with 10G fibre cable between buildings) I have a stack of PE5548 (with its own HDMI stack cable) How would I go about configuring "standalone" PE 5548 with remote stack PE 5548 using 10G fibre between them?   AT x908 --> standalone PE 5548 --> 2 member stack PE 5548   Thanks   Seb
