Table 3-7 Read-Only Transceiver Capabilities
Parameter
100hdx_cap
10fdx_cap
10hdx_cap
The parameters in Table 3-7 define the capabilities of the hardware. The
internal transceiver can support all of these capabilities. The capabilities of the
external transceiver are dependent on the device. If the external transceiver is
not capable of auto-negotiation but has the capability of all speeds and modes
(100 Mbps, 10 Mbps, half-duplex, and full-duplex), you must determine the
capabilities of the external transceiver.
Table 3-8 describes the read-only link partner capabilities.
