Table A-1. Port Settings (Continued)

Parameter	Value	Alias	Description
Task_Management_	0–	TMTO	Timeout value for various firmware operations.
Timeout	65535		For example, timeout value is used for PDUs
			created and transmitted that are not related to
			IOCB and Task Management commands.
TCP_DHCP	on, off	TCPDHCP	When on, the HBA uses DHCP to get its IP
			address, gateway IP address, and subnet mask.
TCP_Nagle	on, off	TCPN	When on, uses Nagle algorithm.
TCP_Time_Stamp	on, off	TCPTMS	When on, puts a timestamp in every transmitted
			TCP segment. Receiver ACKs with timestamp
			so transmitter can calculate RTT and retrans-
			missions. When off, RTT calculated on one out-
			standing segment at a time.
TCP_Timer_Scalea	—	n/a	Each TCP timer is a number of local timer ticks.
			This is a scale factor that adjusts the interval
			between timer ticks on each connection allowing
			faster timeouts on small networks.
TCP_Window_Scale	0–14	WINSCALE	TCP window scale.
VLAN_Enable	on, off	VLAN	When on, VLAN filtering is enabled for the HBA
			(IPv4 traffic only).
VLAN_ID	0–4095	VLANID	When the VLAN_Enable parameter is on, this
			12-bit ID (appended to inbound Ethernet
			frames) must match the ID configured for that
			interface. (IPv4 traffic only).
VLAN_User_Priority	0–7	VLANUPRIOR	When the VLAN_Enable parameter is on, this
			16-bit field is appended to outbound Ethernet
			frames for the TCP connection. (IPv4 traffic
			only).
ZIO	2–16	ZIO	Number of completions the firmware posts to the
			completion queue before interrupting the host
			driver to say there are items in the queue. Valid
			only when FW_ZIO_Enable_Mode is on.
