LAN_FLAGS is a dynamic bitmask system parameter used to enable features in the local area networks port drivers and support code. The default value for LAN_FLAGS is 0.

Bit Definitions

Bit Description
0 The default of zero indicates that ATM devices run in SONET mode. If set to 1, this bit indicates ATM devices run in SDH mode.
1 If set, this bit enables a subset of the ATM trace and debug messages in the LAN port drivers and support code.
2 If set, this bit enables all ATM trace and debug messages in the LAN port drivers and support code.
3 If set, this bit runs UNI 3.0 over all ATM adapters. (Auto-sensing of the ATM UNI version is enabled if both bit 3 and bit 4 are off (0).)
4 If set, this bit runs UNI 3.1 over all ATM adapters. (Auto-sensing of the ATM UNI version is enabled if both bit 3 and bit 4 are off (0).)
5 If set, disables auto-negotiation over all Gigabit Ethernet Adapters.
6 If set, enables the use of jumbo frames over all Gigabit Ethernet Adapters.
7 Reserved
8 If set, disables the use of flow control over all LAN adapters that support flow control.
9 Reserved
10 Reserved
11 If set, disables the logging of error log entries by LAN drivers.
0 If set, enables a fast timeout on transmit requests, usually between 1 and 1.2 seconds instead of 3 to 4 seconds, for most LAN drivers.
0 If set, transmits that are given to the LAN device and never completed by the device (transmit timeout condition) are completed with error status (SS$_ABORT) rather than success status (SS$_NORMAL).
