Type "unknown" Gi0/1

Hello

My 3550 lists its Gi0/1 interface as "unknown", but duplex and speed ont the trunk link is negotiated fine to 1000 - in the other end of the fibre there is a 1000BaseSX SFP.

Should i take any action, as it seems to work fine? (But why does it list the GBIC as unknown? What exact type og GBIC should i use for this connection, and what should the diameter of the fiber patch calbe be? 50 or 62.5?)

Best rgds

Re: Type "unknown" Gi0/1

Is it a Cisco branded GBIC?

It turned out that it was not a Cisco GBIC, but some 3rd. party product.

This explains the unknown message.

Thanx for reply!
