On the cisco side try "switchport nonegotiate" assuming their end is a cisco switch or layer 2/3 router (and not a regular router port).
Note this has NOTHING to do with speed / duplex negotiation, it has to do with the DTP (dynamic trunk protocol) Cisco uses to automatically put a port into trunk mode if two cisco devices in default configurations are connected. This (DTP) can prevent Foundry/Brocade stuff properly linking up. On Mon, Sep 11, 2017 at 12:02 PM, Derek Maxwell < [email protected]> wrote: > Hi Aaron, > > Thanks for responding.
