ISR 4K series Routers

[vimal vikraman]

Need help to understand how many L3 ports are by default there on a ISR4321/K9 router. is it 2 GE ports with additional port with an SFP Module or is it 2 ports where 1 is RJ-45 and another one is with SFP module?

Two L3 ports - one is RJ-45 and for the other one you can choose between RJ-45 and SFP.

• Two GE ports allocated among two RJ45 and one SFP as:

– One combo port with 10/100/1000 RJ-45 Ethernet port or SFP Ethernet port (labeled GE0/0/0)

– One dedicated 10/100/1000 RJ-45 Ethernet port (labeled GE0/0/1)
