Provides a list of definitions and control objects over any 10BASE-T, 100BASE-TX, or 1000BASE-X Cabletron interface that supports auto-negotiation as described by the aforementioned standards.

OBJECT-TYPE

Defines a particular entry containing objects pertaining to definition and control over interfaces supporting Auto-Negotiation.

OBJECT-TYPE

This object controls whether Auto-Negotiation is enabled for the specified port. If Auto-Negotiation is disabled the port will revert to the speed, duplex and flow control settings specified by their associated leaves in the ctEtherManualConfig and ctFlowControl groups.

OBJECT-TYPE

This object indicates whether the remote end of the link is operating Auto-Negotiation signalling or not.

OBJECT-TYPE

This object indicates whether Auto-Negotiation signalling is in progress or has completed.

OBJECT-TYPE

This indicates the technology ability of the local hardware. The value is a sum. This sum initially takes the value zero. Then, for each technology, T, that the port supports, 2 raised to (T - 1) is added to the sum. For example, a port that supports 1000BASE-TFD (T = 18) and 1000BASE-T (T = 17) would return a value of 196608 ((2 ^ (18 - 1)) + (2 ^ (17 - 1))). For ports supporting Auto-Negotiation, values should be calculated as follows: T Technology Description -- ----------- ------------------------------------------------ 1 global Reserved for future use. 2 other None of the following. 3 unknown Initializing, true state or type not yet known 4 10BASE-T 10BASE-T Half Duplex 5 10BASE-TFD 10BASE-T Full Duplex 6 100BASE-T4 100BASE-T4 Half Duplex 7 100BASE-TX 100BASE-TX Half Duplex 8 100BASE-TXFD 100BASE-TX Full Duplex 9 FDX PAUSE Full Duplex Flow Control 10 FDX APAUSE Full Duplex Asymmetric Flow Control 11 FDX SPAUSE Full Duplex Symmetric Flow Control 12 FDX BPAUSE Full Duplex Asymmetric and Symmetric Flow Control 13 100BASE-T2 100BASE-T2 Half Duplex 14 100BASE-T2FD 100BASE-T2 Full Duplex 15 1000BASE-X 1000BASE-X Half Duplex 16 1000BASE-XFD 1000BASE-X Full Duplex 17 1000BASE-T 1000BASE-T Half Duplex 18 1000BASE-TFD 1000BASE-T Full Duplex 19 Rem Fault1 Remote Fault Bit 1 20 Rem Fault2 Remote Fault Bit 2 21 ISO Ethernet IEEE Std 802.9 ISLAN-16T

OBJECT-TYPE

Indicates the advertised ability of the local hardware, but only becomes active on ports that have auto-negotiation enabled. The value is a sum. This sum initially takes the value zero. Then, for each technology, T, that the port is advertising, 2 raised to (T - 1) is added to the sum. For example, a port that advertises 1000BASE-TFD (T = 18) and 1000BASE-T (T = 17) would return a value of 196608 ((2 ^ (18 - 1)) + (2 ^ (17 - 1))). Values for T are limited to technologies supported by the hardware as specified by ctAutoNegLocalTechnologyAbility. For ports supporting Auto-Negotiation, values should be calculated as follows: T Technology Description -- ----------- ------------------------------------------------ 1 global Reserved for future use. 2 other None of the following. 3 unknown Initializing, true state or type not yet known 4 10BASE-T 10BASE-T Half Duplex 5 10BASE-TFD 10BASE-T Full Duplex 6 100BASE-T4 100BASE-T4 Half Duplex 7 100BASE-TX 100BASE-TX Half Duplex 8 100BASE-TXFD 100BASE-TX Full Duplex 9 FDX PAUSE Full Duplex Flow Control 10 FDX APAUSE Full Duplex Asymmetric Flow Control 11 FDX SPAUSE Full Duplex Symmetric Flow Control 12 FDX BPAUSE Full Duplex Asymmetric and Symmetric Flow Control 13 100BASE-T2 100BASE-T2 Half Duplex 14 100BASE-T2FD 100BASE-T2 Full Duplex 15 1000BASE-X 1000BASE-X Half Duplex 16 1000BASE-XFD 1000BASE-X Full Duplex 17 1000BASE-T 1000BASE-T Half Duplex 18 1000BASE-TFD 1000BASE-T Full Duplex 19 Rem Fault1 Remote Fault Bit 1 20 Rem Fault2 Remote Fault Bit 2 21 ISO Ethernet IEEE Std 802.9 ISLAN-16T A successful set operation will result in immediate link re-negotiation if Auto-Negotiation is enabled on this port, as specified by ctAutoNegAdminStatus. A set of this object to a value containing bits that are not supported by the hardware will be successful, but, the port will only advertise values which are the logical AND of the set value and ctAutoNegLocalTechnologyAbility. Note: this re-negotiation will in every case cause temporary link loss during the link re-negotiation. If set to a value that is incompatible with ctAutoNegLocalTechnologyAbility, link negotiation will not be successful and will cause permanent link loss.

OBJECT-TYPE

Indicates the advertised ability of the remote hardware, or link partner. The value is a sum. This sum initially takes the value zero. Then, for each technology, T, that the link partner supports, 2 raised to (T - 1) is added to the sum. For example, a link partner advertising 1000BASE-TFD (T = 18) and 1000BASE-T (T = 17) would return a value of 196608 ((2 ^ (18 - 1)) + (2 ^ (17 - 1))).

The value of enabled(1) indicates that back pressure should be enabled on this port if the port is in half duplex. The value of disable(2) indicates that back pressure should be disabled on this port.

OBJECT-TYPE

The current operational status of back pressure on this port.

OBJECT-TYPE

This indicates the frame based modes of full duplex flow control for this port. The value is a sum. This sum initially takes the value zero. Then, for each mode, M, that the port supports, 2 raised to (M - 1) is added to the sum. For example, a port that supports Symmetric (M= 2), AsymmetricRX (M = 3) and AsymmetricTx (M = 4) would return a value of 14 ((2 ^ (2 - 1)) + (2 ^ (3 - 1)) + (2 ^ (4 - 1))). Speed values should be calculated as follows: M Mode Description -- ------------ ------------------------------------------------ 1 Other None of the following 2 Symmetric Receive and Transmit Pause Frames 3 AsymmetricRx Receive Pause Frames 4 AsymmetricTx Transmit Pause Frames

OBJECT-TYPE

The administrative status requested by management for frame based flow control on this port. For 10 Mb and 100 Mb ports the value of symmetric(1) indicates that if Auto-Negotiation is supported for this port, that the FDX PAUSE bit in the ctAutoNegLocalTechnologyAbility will be set, further indicating that the port supports full duplex flow control. For 1000 Mb the value of symmetric(1) indicates that if Auto-Negotiation is supported for this port, that the FDX SPAUSE bit in the ctAutoNegLocalTechnologyAbility will be set, further indicating that the port supports symmetric frame based flow control. In all cases a set of symmetric(1) will cause the port to interpret received PAUSE frames and allow the port to transmit PAUSE frames when necessary. A set of a value of symmetric(1) is limited to those ports that support symmetric frame based flow control as specified by ctEtherSupportedPauseModes. The value of asymmetricRx(2) indicates that if Auto-Negotiation is supported for this port, that the FDX BPAUSE bit in the ctAutoNegLocalTechnologyAbility will be set, further indicating that the port supports asymmetric receive frame based flow control. In all cases a set of asymmetricRx(2) will cause the port to interpret received PAUSE frames and disallow the port to transmit PAUSE frames. A set of a value of asymmetricRx(2) is limited to those ports that support asymmetricRx frame based flow control as specified by ctEtherSupportedPauseModes. The value of asymmetricTx(3) indicates that if Auto-Negotiation is supported for this port, that the FDX APAUSE bit in the ctAutoNegLocalTechnologyAbility will be set, further indicating that the port supports asymmetric transmit frame based flow control. In all cases a set of asymmetricTx(3) will cause the port to ignore PAUSE frames and allow the port to transmit PAUSE frames when necessary. A set of a value of asymmetricTx(3) is limited to those ports that support asymmetricTx frame based flow control as specified by ctEtherSupportedPauseModes. The value of disabled(4) indicates that if Auto-Negotiation is supported for this port, that the FDX PAUSE, FDX APAUSE, FDX SPAUSE and FDX BPAUSE bits in the ctAutoNegLocalTechnologyAbility will be cleared, further indicating that the port does not support frame based flow control. In all cases a set of disable(2) will cause the port to ignore received PAUSE frames and to disallow the port to transmit PAUSE frames. The value of autonegotiate(5) indicates that if Auto-Negotiation is supported for this port, and the hardware supports the ability to advertise PAUSE capability, that the maximum flow control capabilities of the hardware are to be reflected in the PAUSE bits of ctAutoNegLocalTechnologyAbility. The ports flow control operational state will be determined by the results of Auto-Negotiation. If Auto-Negotiation is not supported for this port, a set of autonegotiate(5) will fail. In all cases frame based flow control is only used for ports that are in full duplex.

OBJECT-TYPE

The current operational status of full duplex flow control on this port. A value of unknown(5) will be returned for any port which has a Pause Frame Admin Status of autonegotiate(5), as specified by ctFlowCtlPauseAdminStatus, but is in an unknown Auto-Negotiation state.

OBJECT-TYPE

Defines a particular entry containing objects pertaining to definition and control over Cabletron Ethernet interfaces.

OBJECT-TYPE

This indicates the supported speeds for the port. The value is a sum. This sum initially takes the value zero. Then, for each speed, S, that the port supports, 2 raised to (S - 1) is added to the sum. For example, a port that supports 10 Mb (S = 1) and 100 Mb (S = 2) would return a value of 3 ((2 ^ (1 - 1)) + (2 ^ (2 - 1))). Speed values should be calculated as follows: S Speed Description -- ----------- ------------------------------------------------ 1 10 Mb Ethernet 2 100 Mb Fast Ethernet 3 1000 Mb Gigabit Ethernet

OBJECT-TYPE

The administrative status requested by management for the speed of this port. The value of tenmegabit(2) indicates that if Auto-Negotiation is disabled for this port, that the port will operate at a speed of 10 megabits per second, provided that the port supports that speed, as specified by ctEtherSupportedSpeed. The value of hundredmegabit(3) indicates that if Auto-Negotiation is disabled for this port, that the port will operate at a speed of 100 megabits per second, provided that the port supports that speed, as specified by ctEtherSupportedSpeed. The value of gigabit(4) indicates that if Auto-Negotiation is disabled for this port, that the port will operate at a speed of 1000 megabits per second, provided that the port supports that speed, as specified by ctEtherSupportedSpeed. In all cases, if the value specified does not indicate a speed that the port supports the set will fail.
