options.
The sum (integer) of the values in the

command on PROCESS
ztsaTcpIpProcess:
ZSTATS-IP-BAD-XSUM
ZSTATS-IP-TOO-SHORT
ZSTATS-IP-TOO-SMALL
ZSTATS-IP-BAD-HDR-LEN
ZSTATS-IP-BAD-LEN
ipForwDatagrams

read-only
Counter
The number of input
datagrams that
required forwarding.
The value (integer) of the ZSTATS-IP-FWD

PROCESS ztsaTcpIpProcess:
ZSTATS-IP-BAD-XSUM
ZSTATS-IP-TOO-SHORT
