‘Token Ring NIC’ - returned for the NIC, for Token Ring
‘DDS Network Interface’ - returned for the DDS inter-
face
‘DDS DTE RS-232/V.35 Port’ - returned for DTE Port
ifType: (read-only)
The type of interface, distinguished according to the physi-
cal/link protocol(s) immediately ‘below' the network layer
in the protocol stack.

ifMtu: (read-only)
The size of the largest datagram which can be sent/received
on the interface, specified in octets. For interfaces that are
used for transmitting network datagrams, this is the size of
the largest network datagram that can be sent on the inter-
face.
296 - returned for the SLIP Interface
1500 - returned for the NIC interface (if Ethernet)
2000 - returned for the NIC interface (if Token Ring)
0 - returned for the DDS and Port 1 interfaces
ifSpeed: (read-only)
An estimate of the interface's current bandwidth in bits per
second. For interfaces which do not vary in bandwidth or
for those where no accurate estimation can be made, this
object should contain the nominal bandwidth
9600 - returned for the SLIP Interface at 9600 baud
19200 - returned for the SLIP Interface at 19200 baud
38400 - returned for the SLIP Interface at 38400 baud
56000 - returned for the SLIP Interface at 56000 baud
10000000 - returned for the NIC (if Ethernet)
4000000 - returned for the NIC (if Token Ring at 4 Mbps)
16000000 - returned for the NIC (if Token Ring at 16
Mbps)
ifPhysAddress: (read-only)
The interface's address at the protocol layer immediately
‘below' the network layer in the protocol stack. For inter-
faces which do not have such an address (e.g., a serial line),
this object should contain an octet string of zero length. One
exception is the NIC interface which returns the physical
address of the unit
ifAdminStatus: (read-write)
The desired state of the interface. The testing(3) state indi-
cates that no operational packets can be passed. For the
PRISM 4151, you do not have write permission.
up(1) - Ready to pass packets
down(2)
testing(3) - In test mode
ifOperStatus: (read-only)
The current operational state of the interface. The testing(3)
state indicates that no operational packets can be passed.
up(1) - Ready to pass packets. This value is returned if
the interface is active, and does not have a testing status.
down(2) - Returned if the interface is not enabled
testing(3) - In test mode. This value is returned for the
DDS and DTE interfaces if the interface has a test loop or
BERT active.
IfLastChange: (read-only)
The value of sysUpTime at the time the interface entered its
current operational state. If the current state was entered
prior to the last re-initialization of the local network man-
agement subsystem, then this object contains a zero value.
