Trying it on an ASR 1006 turned out to not be as straight forward. We had to use a 'hidden command'.
*Mar 28 11:07:49.547: %TRANSCEIVER-6-REMOVED: SIP0/3: Transceiver module removed from POS0/3/0 *Mar 28 11:07:59.542: %TRANSCEIVER-6-INSERTED: SIP0/3: transceiver module inserted in POS0/3/0 *Mar 28 11:08:01.160: %ASR1000_RP_ALARM-6-INFO: CLEAR CRITICAL xcvr container 0/3/0 Transceiver Missing - Link Down *Mar 28 11:08:01.161: %ASR1000_RP_ALARM-6-INFO: ASSERT CRITICAL POS0/3/0 Physical Port Link Down *Mar 28 11:08:01.124: %TRANSCEIVER-3-NOT_SUPPORTED: SIP0/3: Detected for transceiver module in POS0/3/0, module disabled
Next the command is run:
FW-LB-Rtr(config)#service un? % Unrecognized commandThe above tells you that its hidden and won't come up under context help by typing a question mark.
FW-LB-Rtr(config)#service unsupported-transceiverYou get a warning as shown below so be careful what you do or don't do:
Warning: When Cisco determines that a fault or defect can be traced to the use of third-party transceivers installed by a customer or reseller, then, at Cisco's discretion, Cisco may withhold support under warranty or a Cisco support program. In the course of providing support for a Cisco networking product Cisco may require that the end user install Cisco transceivers if Cisco determines that removing third-party parts will assist Cisco in diagnosing the cause of a support issue. FW-LB-Rtr(config)#
and our interface came up
*Mar 28 12:28:36.354: %LINK-3-UPDOWN: SIP0/3: Interface POS0/3/0, changed state to up *Mar 28 12:28:37.372: %LINEPROTO-5-UPDOWN: Line protocol on Interface POS0/3/0, changed state to up
Please note the command is supported on some switches.
