router#sh int gigabitEthernet 8
GigabitEthernet8 is up, line protocol is up
  Hardware is PQ3_TSEC, address is XXX)
   MTU 1500 bytes, BW 1024 Kbit/sec, DLY 10 usec,
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation 802.1Q Virtual LAN, Vlan ID  1., loopback not set
  Keepalive set (10 sec)
  Full Duplex, 1Gbps, media type is LX
  output flow-control is unsupported, input flow-control is unsupported
  ARP type: ARPA, ARP Timeout 04:00:00
  Last input 00:00:00, output 00:00:00, output hang never
  Last clearing of "show interface" counters 2w2d
....

Thanks to all of you for your help!

HI there,

I don't have a 891 to test on, but the following command might work:

sh int gi8 trans det

cheers,

hmmmm maybe the 891 doesn't support DOM. As a last ditch effort, see if the following config works:

!
transceiver type all
  monitoring
!

Then see if the following command is accepted:

show interface transceiver

cheers,

Seb.

The command "Transceiver "is not supported .
i still have the problem .

it must be possible to read the values !

with a 4300 it goes ....
Router #sh hw-module subslot 0/0 transceiver 0 status   (GigabitEthernet0/0/0)

The Transceiver in slot 0 subslot 0 port 0 is enabled.

  Module temperature                        = +49.273 C

  Transceiver Tx supply voltage             = 3198.0 mVolts

  Transceiver Tx bias current               = 22550 uAmps

  Transceiver Tx power                      = -5.6 dBm

  Transceiver Rx optical power              = -7.2 dBm
