You are correct about the presented interfaces but what i am saying is the the !1 Ethernet/IEEE 802.3 interface(s)" could not be distinguished or should i assumed that it was just software issue?, because the the 16 repeater interfaces, the 2 serials, console and the AUX could physical be seen but not any AUI.
I would not assume that it is a software issue. It has been a long time since I have worked with a 2507 and my memory is not exact about it. But most of the 2500 routers had Ethernet interfaces with the AUI connector. Can you tell me whether there are any interfaces on the back of the router that are labeled Ethernet or are labeled AUI?
Well I have done some more research and I find this link which seems to indicate that the 2507 has 16 ports that act as an Ethernet hub but does not indicate that it has a regular (routed) Ethernet interface:
I have not been able so far to find anything that specifies how to configure it, but I am guessing from the context of what I am seeing that you configure Ethernet 0 with an IP address (and any other parameters that you think appropriate) as a virtual interface to provide routing for the virtual LAN that is created by the hub ports.
So plug a PC into one of the hub ports (and issue the hub 0 0 15 no shut to make sure that the ports are not shut down), configure an IP address on the PC, and configure an IP address on Ethernet 0 which is also configured as the default gateway for the PC plugged into a hub port.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
