configuring old switches (still working and in use) to be part of the newer ip sub-network and be able to connect and monitor them.

we have a mix of newer cisco switches in our network, and a batch of older switches in the network.

the old switches are mainly for routing old wiring in the building, and some provide fiber channels to other locations.  

the newer switches handle all of the PoE phones as well as routing.

the old ones were never removed because at that time, budget and time were minimal.  so it was basically put in and get it working.

---------------------

i am in the process of getting all of the switches on the same subnetwork for monitoring and maintenance.


using the Cisco Network Assistant, i can map out all of the routers and switches in the network. (except for a majority of the old ones).

over the past week i went to every old switch (about 10 now), used the console to change all of the passwords (enable and telnet) to the same thing.

I had configuration for each one ready to go, and applied it to them, but i can't "see" them with CDP, but can't connect to them for management.



Example Below:
-------------------
My PC = 10.10.8.20

Router = (10.10.8.1, 10.1.1.1)

newSwitch7 = 10.1.1.7

oldSwitch19 = 10.1.1.19

CDP tells me the link is up / working, but i can't connect to it to manage the switch..  
snapshots of the configs are below.  if you need to know anything else, just ask:

**dont worry about the details like link speeds and such
**a lot of it isn't in use, but proally has 6-8 ports still active
