debug ip tcp sack
Displays information about TCP Selective-ACK packets.
EXAMPLE:
ProCurveRS# debug ip tcp sack
After you enter this command, messages such as the following appear at the destination specified for debugging
output. You can turn off these messages with the no debug ip tcp sack command.
TCP: process ACK, tcp state tcp_syn_recd

Possible values: N/A
Default value: N/A
debug ip tcp transactions
Displays information about TCP transactions, including state changes and packet retransmissions.
EXAMPLE:
ProCurveRS# debug ip tcp transactions
After you enter this command, messages such as the following appear at the destination specified for debugging
output. You can turn off these messages with the no debug ip tcp transactions command.
TCP: 1.1.1.1:23 -> 1.1.1.2:2537: state change LISTEN -> SYN-RECEIVED

TCP: retransmitted segment
TCP: 1.1.1.1:23 -> 1.1.1.2:2537: state change ESTABLISHED -> FIN-WAIT-1
TCP: retransmitted segment
TCP: 1.1.1.1:23 -> 1.1.1.2:2537: state change FIN-WAIT-1 -> FIN-WAIT-2
TCP: 1.1.1.1:23 -> 1.1.1.2:2537: state change FIN-WAIT-2 -> TIME-WAIT
