IP Frame Types
The hub supports both ETHERNET_II and ETHERNET_SNAP for its Ethernet
IP communications. The default frame type is ETHERNET_II. However, many
networks composed of FDDI, token ring, and Ethernet topologies require the
ETHERNET_SNAP frame type for routing, bridging, and switching. To
provide IP management flexibility, the 2824 hub supports both ETHERNET_II
and ETHERNET_SNAP frame types.
Although the hub supports two different Ethernet frame types, it cannot support
both simultaneously. This is because an individual IP network can only use one
frame type and different frame types require different IP networks even if they
run on the same cable.
