Sometimes you log onto a switch remotely and need to know what kind of optical interface the switches actually have plugged in. It’s pretty simple:
Switch#show interface gi1/0/25 capabilities GigabitEthernet1/0/25 Model: WS-C3750G-24TS Type: 1000BaseLX SFP Speed: 1000 Duplex: full Trunk encap. type: 802.1Q,ISL Trunk mode: on,off,desirable,nonegotiate Channel: yes Broadcast suppression: percentage(0-100) Flowcontrol: rx-(off,on,desired),tx-(none) Fast Start: yes QoS scheduling: rx-(not configurable on per port basis), tx-(4q3t) (3t: Two configurable values and one fixed.) CoS rewrite: yes ToS rewrite: yes UDLD: yes Inline power: no SPAN: source/destination PortSecure: yes Dot1x: yes
The most important things here is that you can see I have a 1000BaseLX SFP installed.

While studying for my CCNP I created a large amount of practice labs. I used these on the lab I created at work. The labs themselves fit into this topology but feel free to change it to fit yours. I’ll post a couple each day that focuses on a specific technology or procedure for 1 exam.
This is the topology I used:
Before starting an exam I’m sure to remove all old config (as well as doing a delete vlan.dat on the switches.) I also shut down all ports on the switches using the port range command and only open the ports needed for the particular lab. This prevents packets from leaking out when I’ve switched off 1 port hoping to cut a connection. Remember switches have all ports open by default, unlike routers which are admin shut by default
