cisco 2516 router 8 years 10 months ago #24005

quick question.

I purchased a cisco 2516 router which comes with a "14 port Hub integrated with the router which enable you connect to 14 Ethernet devices without AUI transceivers"

Now when I look at the running-config it shows the following:

hub ether 0 1
link-test
auto-polarity
!
hub ether 0 2
link-test
auto-polarity
!
hub ether 0 3
link-test
auto-polarity
!
hub ether 0 4
link-test
auto-polarity


01 through 14.

how come they don't show up as an interface like ethernet0, serial0, etc.

interface Ethernet0
no ip address
no ip route-cache
no ip mroute-cache
shutdown

Can an ip address be assigned to each of these ports?

I have never heard of that type of device so I am only making assumptions.

A hub is a layer 1 (physical) device and does not understand MAC address or IP addresses. It is almost just a large "Y" connector of all the cables. It simply connects the devices together.

If the hub is the same as a normal hub, I would not think you could assign it an IP or control it in anyway for that matter.

To my knowledge, you only assign IP address to router interfaces and other devices like a switch (for management). You don't even assign IP addresses to switch ports.

Were you wanting to use the hub ports as interfaces?

Yes I was planning on using them as interfaces. They were falsely advertised as 14 ethernet interfaces. Oh well, i'll just have to use serial instead.

thanks for your help.

after reading through lots of docs it appears that the interface of Ethernet0 on the route represents all 14 "hub" ethernet ports.
