I am setting up an EX4600/4300 virtual chassis to replace an existing cisco core stack.
I have configured several aggregate ports and have set the unit 0 interface-mode to trunk. I notice that there is also an option to set vlan-tagging on the interface such as: set interface ae0 vlan-tagging. I am not sure if this is required though. I am not using subinterfaces.
On the current cisco switches I am used to having to set "switchport trunk encapsulation dot1q" so coming from cisco I wonder if an equivalent command is needed on the juniper (ie vlan-tagging)?
Also, worth mentioning, is access switches are still Cisco. Are there other considerations for interoperability with cisco/juniper trunking? The config on all Ciscos is quite basic. Example:
interface Port-channel1
description Link to CoreStack
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1-10,100,102
switchport mode trunk
switchport nonegotiate
thanks
