rxicmp_err_frms
Number of good IP datagrams whose ICMP payload has a checksum error
rxipv4_gd_octets
Number of bytes received in good IPv4 datagrams encapsulating TCP, UDP, or ICMP data
rxipv4_hdrerr_octets
Number of bytes received in IPv4 datagrams with header errors (checksum, length, version mismatch).
The value in the Length field of IPv4 header is used to update this counter
rxipv4_nopay_octets
Number of bytes received in IPv4 datagrams that did not have a TCP, UDP, or ICMP payload. The value in
the IPv4 headers Length field is used to update this counter
rxipv4_frag_octets
Number of bytes received in fragmented IPv4 datagrams. The value in the IPv4 headers Length field is
used to update this counter
rxipv4_udsbl_octets
Number of bytes received in a UDP segment that had the UDP checksum disabled. This counter does not
count IP Header bytes
rxipv6_gd_octets
Number of bytes received in good IPv6 datagrams encapsulating TCP, UDP or ICMPv6 data
rxipv6_hdrerr_octets
Number of bytes received in IPv6 datagrams with header errors (length, version mismatch). The value in
the IPv6 headers Length field is used to update this counter
rxipv6_nopay_octets
Number of bytes received in IPv6 datagrams that did not have a TCP, UDP, or ICMP payload. The value in
the IPv6 headers Length field is used to update this counter
rxudp_gd_octets
Number of bytes received in a good UDP segment. This counter does not count IP header bytes
rxudp_err_octets
Number of bytes received in a UDP segment that had checksum errors
rxtcp_gd_octets
Number of bytes received in a good TCP segment
rxtcperroctets
