Various hardware switch vendors with fiber NIC modules


In Packetwise 8.6.4 and earlier versions, the PacketShaper 12000 fiber-optic NIC has trouble negotiating speeds with certain devices.  This is a short list of switches which may exhibit the fiber negotiation issue:

Cisco 2960G
Cisco 3560G
Cisco 3750E
