`How to understand in iterface what type of sfp is plugged? How you make difference with Multimode and Single mode?
I use these commands:
show inventory
show interface status
show interface <interface name>
For example:
show interface status
Gi0/24 connected trunk a-full a-1000 1000BaseLX SFP
show inventory
PID: WS-C2960G-24TC-L , VID: V03, SN: FOC1250W0K0

NAME: "GigabitEthernet0/24", DESCR: "1000BaseLX SFP"
PID: , VID: , SN:
show interface g0/24

Maybe LX is mean the type of sfp module?
LX is for what type of sfp? Single mode?
SX is for Multimode?
