Description
(RXLTERL0, RXLTERL1) A count of frames received that
were at least 64 bytes in length where the length/type field
contained a length value that did not match the number of
MAC client data bytes received. The counter also
increments for frames in which the length/type field
indicated that the frame contained padding, but where the
number of MAC client data bytes received was greater than
64 bytes (minimum frame size). The exception to the this is
when the Length/Type Error Checks are disabled in the
chosen MAC, which case this counter will not increment.
(RXLTERU0, RXLTERU1) A count of frames received that
were at least 64 bytes in length where the length/type field
contained a length value that did not match the number of
MAC client data bytes received. The counter also
increments for frames in which the length/type field
indicated that the frame contained padding, but where the
number of MAC client data bytes received was greater than
64 bytes (minimum frame size). The exception to the this is
when the Length/Type Error Checks are disabled in the
chosen MAC, which case this counter will not increment.
(RXVLANFL0, RXVLANFL1) A count of error-free VLAN
frames received. This counter will only increment when the
receiver is configured for VLAN operation
RXVLANFU0, RXVLANFU1) A count of error-free VLAN
frames received. This counter will only increment when the
receiver is configured for VLAN operation
(RXPFL0, RXPFL1) A count of error-free frames received
that:
Contained the MAC Control type identifier 88-08 in the
length/type field
Contained a destination address that matched either the
MAC Control multicast address or the configured source
address of the MAC
Contained the PAUSE opcode
Were acted upon by the MAC
(RXPFU0, RXPFU1) A count of error-free frames received
that:
Contained the MAC Control type identifier 88-08 in the
length/type field
Contained a destination address that matched either the
MAC Control multicast address or the configured source
address of the MAC
Contained the PAUSE opcode
Were acted upon by the MAC
(RXUOPFL0, RXUOPFL1) A count of error-free frames
received that contained the MAC Control type identifier 88-
08 in the length/type field but were received with an opcode
other than the PAUSE opcode.
(RXUOPFU0, RXUOPFU1) A count of error-free frames
received that contained the MAC Control type identifier 88-
08 in the length/type field but were received with an opcode
other than the PAUSE opcode.
