Index
|
A unique value, greater than zero, for each interface. The values are assigned contiguously, starting from 1. This is a read-only field.
|
Descr
|
A textual string containing information about the interface. This string should include the name of the manufacturer, the product name, and the version of the interface hardware/software. This is a read-only field.
|
Type
|
The type of interface, which is determined by the physical/link protocol or protocols immediately below the network layer in the protocol stack. The 1600 Series switch supports the following types: other (1), ethernetCsmacd (6), gigabitEthernet (117), l2vlan (135), and ipForward (142). This is a read-only field.
|
Mtu
|
The size of the largest packet which can be sent or received on the interface, specified in octets. For interfaces that are used for transmitting network datagrams, this is the size of the of the largest network datagram that can be sent on the interface. This is a read-only field.
|
Speed
|
An estimate of the interface's current bandwidth in bits per second. For interfaces that do not vary in bandwidth or for those where no accurate estimation can be made, this object should contain the nominal bandwidth. If the bandwidth of the interface is greater than the maximum value that can be reported by this object, then this object should report its maximum value (4, 294, 967, 295) and ifHighSpeed must be used to report the interface's speed. For a sub-layer for which bandwidth has no meaning, this object is 0. This is a read-only field.
|
PhysAddr
|
The interface's address at its protocol sub-layer. For example, for an 802.x interface, this object normally contains a MAC address. The interface's media-specific MIB must define the bit and byte ordering and the format of the value of this object. For interfaces that do not have such an address (for example, a serial line), this object should contain an octet string of zero length. This is a read-only field.
|
AdminStatus
|
The desired state of the interface. The testing state indicates that no operational packets can be passed. When a managed system initializes, all interfaces start with AdminStatus in the down state. As a result of either explicit management action or per configuration information retained by the managed system, AdminStatus is then changed to either the up or testing state (or remains in the down state). This is a read-write field.
|
OperStatus
|
The current operational state of the interface. The testing state indicates that no operational packets can be passed. If AdminStatus is down, then OperStatus is down. If AdminStatus is changed to up, then OperStatus is changed to up if the interface is ready to transmit and receive network traffic. OperStatus should change to dormant if the interface is waiting for external actions (such as a serial line is waiting for an incoming connection). OperStatus should remain in the down state if there is a fault that prevents it from going to the up state. It should remain in the noPresent state if the interface has missing (usually hardware) components. This is a read-only field.
|
LastChange
|
The value of sysUpTime at the time the interface entered its current operational state. If the current state was entered prior to the last-reinitialization of the local network management subsystem, then this object is 0. This is a read-only field.
|
LinkTrap
|
Indicates whether link up or link down traps should be generated on this interface. By default, the value is enabled. This is a read-write field.
