COUNTER MEANING
ALGM_ERR This is the number of frames received with alignment errors (odd number of nibbles).
SINGLE_COL A count of successfully transmitted frames for which transmission is inhibited by exactly one
collision.
MUL_COL A count of successfully transmitted frames for which transmission was inhibited by more than
one collision.
LATE_COL The number of times that a collision was detected on a particular interface later than 512 bit-
times into the transmission of a packet.
EXC_COL A count of frames for which transmission failed due to excessive collisions. Excessive collision
is defined as the number of maximum collisions before the retransmission count is reset.
MACRX_ERR This counter contains the number of frames received that were less than 64 bytes. These
frames are discarded.
CS_ERR The number of times that the carrier sense condition was lost or never asserted when
attempting to transmit a frame on a particular interface.
FTL_ERR This counter contains the number of frames received that were more than maximum length
(1536 bytes). These frames are discarded.
FCS_ERR Frame Check Sequence Errors.
OTO A count of data and padding octets of frames that are successfully transmitted.
ORO A count of data and padding octets of frames that are successfully received.
BCF A count of frames that are successfully received and are directed to the broadcast group
address.
RXPAUS The number of received PAUSE packets.
TXPAUS The number of PAUSE packets transmitted.
TXBCNT This counter indicates the number of valid data frames that have been transferred over the
transmit channel.
RXBCNT This counter indicates the number of valid data frames that have been transferred over the
receive channel.
TX_DEF A count of frames for which the first transmission attempt was delayed because the Ethernet
media was busy.
12.3.2 Clear Ethernet Counters
vdsl enet clear chan-id
This command clears the Ethernet Counters of VES-1000 Series switch and the VDSL modem (if connected to the
VES-1000 Series switch).
