Question: How to wire two 2960 switch base on a config file?

[davidnghk]

The story,

the network engineer resign, I am the new guy with normal home network knowledge, as I am not applying the network engineer position, but somehow I got his task: replacing the switch.

the site contain the network equipment can only visit once per month.

I have not yet visit the site, and the last network engineer did not left any "network diagram", and I hear the wiring to both switch already disconnected, so I have no idea the wiring to the switch.

Need help on figure out the network diagram.

the only thing I know, hear from the guard that was watching the last network engineer work:

1. two switch in that site, I hear it is for redundancy, one of them broken, one of them is good, and the good one is in my hand, and I have access to its config.

2. the two switch model are WS-C2960-8TC-S, I hear they have different IP.

3 there is two firewall, I don't know the model.

4. might be two ISP cable connect to the internet, or might be just one, not sure.

5. one server, I assume it has two NIC port.

6. I hear the "SFP Modules" in the switch might be used.

7. the config of the good switch

got this disconnected photo from the guard

seems simple, right? for each switch

• fiber cable to SFP in the switch
• RJ45 to port 0 or port 7

so the purpose of the switch is convert the fiber signal to RJ45?

there is no fail over ? or am I missing something?

[balaji.bandi]

as per the information switch action as Layer 2 switch, but the failed switch is part of stack may be ?

can you check from working switch, show switch ( post output here)

we are also same like your guess, based on the cables ?

where is this yellow cable going ? to other switch ? what port they connected ?

[davidnghk]

I already show the working switch config in my first post.

the yellow cable is the fiber cable, I guess it is to the switch.

[balaji.bandi]

Pay more attention what we asked for  - show switch ( post output here)

The yellow cable is the fiber cable, I guess it is to the switch.  - if you sure please carry on test it..what are you waiting for ?
