FDDI Management
FDDI SNAP
The FDDI SNAP frame type has an FDDI header with a Frame Control field that provides FDDI framing information, and the 802.2 LLC header with FDDI Frame Control, a SNAP LSAP identifier, and a five byte protocol identifier.
There is no FDDI equivalent for Ethernet 802.3 Raw frames or Ethernet II frames. Ethernet/FDDI bridges will automatically translate Ethernet II frames into FDDI SNAP frames, by identifying it as a SNAP frame in the LLC header, and inserting a SNAP header with the Ethernet Type field.
By default,
FDDI Frame Translation Options
The FDDI Translation window lets you select which translation methods you want enforced when translating frames from an FDDI frame format into an Ethernet frame format, and when translating Ethernet Raw frames into FDDI frames. It also lets you choose whether to allow fragmentation of IP datagrams into smaller datagrams, and enable or disable the Auto Learn Novell Frame Translation option.
To set frame translation parameters:
1.Click on the selection boxes of interest (described below), and drag to select the desired translation options.
2.Click Apply to save your new frame translation settings at the device, or click Cancel to restore the last saved options.
IP Fragmentation
The IP Fragmentation selection box lets you specify frame fragmentation parameters. FDDI traffic may need to be split, or fragmented, into two, three, or four smaller frames to be successfully transmitted on an Ethernet network. For fragmentation to be allowed, the frame must be an FDDI SNAP frame with an OUI of
