Problem When you insert specific GBICs on a Catalyst 3850 switch you may get following error logs: %PLATFORM_PM-6-MODULE_ERRDISABLE: The inserted SFP module with interface name Gix/y/z is not supported%PM-4-ERR_DISABLE: gbic-invalid error detected on Gix/y/z, putting Gix/y/z in

err-disable state Issue has commonly been seen with GLC-SX-MMD and third party SFPs. Solution Please keep in mind the following points before considering this as a hardware issue with the SFP, sub-module (C3850-NM) or 3850 backplane. 1 . Verify compatibility between the SFP and the switch, sub-module and software version. You can refer these compatibility matrix documents. Gigabit Ethernet Transceiver Modules Compatibility Matrix 10-Gigabit Ethernet Transceiver Modules Compatibility Matrix 2 . Some SPFs need configuration and actions to be able to work in a Catalyst 3850 switch (mostly when they are manufactured by third-party). Try following actions: 3850(config)# no errdisable detect cause gbic-invalid 3850(config)# service unsupported-transceiver Remove SFP module, shutdown/no shutdown the port, insert back the SFP module. 3 . Take into consideration the following software defects: CSCut94443 - GLC-SX-MMD is not recognized after OIR CSCuj31712 - certain Vendor Sfp force ports to err-disable upon OIR It is recommended to go to stable version of code whether if you are hitting those bugs or not.

is very twitchy when it comes to compatibility with other vendors; platform_pm 6 module_errdisable like Juniper for instance, that can detect and operate on a pure Cisco SFP or GBIC. %GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: phy 4 sfp_not_supported GBIC in port Gi0/1 has bad crc %PM-4-ERR_DISABLE: gbic-invalid error detected on Gi0/1, putting Gi0/1 in err-disable state The above error is generated when you insert a non-Cisco http://www.cisco.com/c/en/us/support/docs/interfaces-modules/gbics/200296-Unsupported-GBIC-SFP-in-sub-module-of.html GBIC into a Cisco switch. After the switch detect the unsupported GBIC, it puts the interface in an error-disabled mode so that it can protect it self from errors, malfunctions and so on. The idea is most GBICs have almost the same architecture, and are supposed to work on almost all Vendors, but sometimes the IOS may http://switchpacket.blogspot.com/2013/06/getting-unsupported-gbics-to-work-on.html not support that piece of hardware; a more recent IOS version might. but in any cases, here's how to make it work using these hidden commands service unsupported-transceiver no errdisable detect cause gbic-invalid They run in the global configuration mode. As the commands imply, the first is to tell IOS to ignore the fact that the GBIC is not supported and the second command is to prevent IOS from putting the interface in Err-Disabled mode. Just make sure you don't use these commands on a production box, because it will teardown your warranty..

Hey guys, so I've been successfully able to make https://networkingnerd.net/2013/02/28/why-is-my-sfp-not-working/ a fiber etherchannel between my 3750G's upon themselves, but I'm trying to connect the 3750G (Master) in a uplink to my HP Procurve 2910al and I'm getting a error detected bad crc error: 00:10:02: %GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port 65564 has bad crc 00:10:02: %PM-4-ERR_DISABLE: gbic-invalid error detected on Gi1/0/28, putting Gi1/0/28 in err-disable state 00:10:04: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/28, changed state to down .................................................. .. here is the config on the 3750G - it's a factory reset, basic config only. anyone see something I'm missing? - at the invalid error detected bottom will be the HP Procurve. Only thing I can think of is maybe the 3750G needs a firmware update. I've tried a Netgear, Dell, and HP Gbic stick and they all give the same crc. Even brand-new Netgeat carrot sticks; i'm perplexed. --------------------------------------------- Switch# Switch#show ver Cisco IOS Software, C3750 Software (C3750-IPBASEK9-M), Version 12.2(25)SEB1, RELEASE SOFTWARE (fc1) Copyright (c) 1986-2005 by Cisco Systems, Inc.
