Hi, our ISP is Level3, we subscribe FastE 100Mbps line from them.
Level3 sets the interface to our building as 100Full no auto negotiation,
The building, facility provider has Brocade 4802 switch between Level3 demarc and our rack,
4802 interface also set to 100/Full.
With this settings on 4802, our port is negotiating to half duplex, resulting poor performance.
Why would this happen when both facility switch and level 3 switch are set 100/Full??
Is this a known 4802 bug? Or does 4802 work at all with CISCO switches?
