Cisco SFP Determination

So if you do a sh int G0/0/1 (or similar), you don't see something like:

Full-duplex, 1000Mb/s, link type is auto, media type is 1000BaseZX SFP?

And if you do:

sh int g0/25 capabilities

GigabitEthernet0/25
  Model:                 WS-C3560G-24TS
  Type:                  1000BaseZX 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

Your sho int ten0/25 should have worked it would look similar to one of the following:

Full-duplex, 10Gb/s, media type is 10Gbase-SR - has installed

Full-duplex, 10Gb/s  - not installed

You can also do a 'sh inv' and that will list all hardware installed and where it is located.

Thanks guys/gals

going to try your suggestions now...

Experts,

This is what I see:

Hostname#show int gig 1/0/4
GigabitEthernet1/0/4 is down, line protocol is down
  Hardware is GigabitEthernet, address is 0007.84ad.686a (bia 0007.84ad.686a)
  MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, rely 255/255, load 1/255
  Encapsulation ARPA, loopback not set
  Keepalive set (10 sec)
  Full Duplex, 1000Mbps, link type is autonegotiation, media type is missing
  output flow-control is on, input flow-control is on
  ARP type: ARPA, ARP Timeout 04:00:00
  Last input never, output never, output hang never
  Last clearing of "show interface" counters never
  Queueing strategy: fifo
  Output queue 0/40, 0 drops; input queue 0/75, 0 drops
        Available Bandwidth 1000000 kilobits/sec
  5 minute input rate 0 bits/sec, 0 packets/sec
  5 minute output rate 0 bits/sec, 0 packets/sec
     0 packets input, 0 bytes, 0 no buffer
     Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
     0 watchdog, 0 multicast, 0 pause input
     0 packets output, 0 bytes, 0 underruns
     Transmitted 0 broadcasts
     0 output errors, 0 collisions, 0 interface resets
     0 babbles, 0 late collision, 0 deferred
     0 lost carrier, 0 no carrier, 0 pause output
     0 output buffer failures, 0 output buffers swapped out

i don't have the 'capabilities' option

Experts,

Show 'inv' didn't tell if there is an SFP in gig 1/0/4

are you able to do the 'sh inv' command?

Then I'm inclined to say there isn't an SFP in that slot.  That should show everything installed.

Show 'inv' didn't tell if there is an SFP in gig 1/0/4

Could you show the output of the command?

Full Duplex, 1000Mbps, link type is autonegotiation, media type is missing

Unfortunately this is telling us the SFP is not recognized.   Could you try a different SFP in the port or try a different port?

I guess ...oops!

Cheers

Oooops is not a four letter word ;)

Thx 4 the points.
