07 Sep Cisco TAC and service unsupported-transceiver and no errdisable detect cause gbic-invalid commands

   As we all know, using 3rd party optical transceivers can help to save a lot of CAPEX. However, there can be situations when third party transceiver causes equipment malfunction then Cisco has rights to withhold equipment warranty (as we have discussed in blog “ 3rd Party Components & Vendor Warranty ”).

 

Normally when we get below type of Alarm in Cisco switches:

%PLATFORM-SFP-3-DEV_SFP_PID_NOT_SUPPORTED
PID: DWDM-10G-SFP-31.90,
Or

%PHY-4-UNSUPPORTED_TRANSCEIVER: Unsupported transceiver found in Gi1/0/0

Or

%GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port 65538 has bad crc

We can simply input below commands:
– service unsupported-transceiver,
– no errdisable detect cause gbic-invalid

 

  These commands allow switch to ignore wrong Part ID`s in the optical module coding and help to bring third party optical transceiver to life. However, there are reports from actual Cisco router and switch users that in case of trouble, it could become very difficult to use Cisco TAC (Technical Assistance Centre) because these commands are present in switch/router global configuration file.

  Here if switch/router is in critical location, which might require Cisco TAC support, we would recommend contacting us [email protected] and we will check if we have experience in your platform with required modules and we might help with matching products so that solution will works perfect without any need for below commands:
– service unsupported-transceiver,
– no errdisable detect cause gbic-invalid

 

Cheers and keep in touch
