Use the command-line interface
at\smib=mib-2.interfaces.iftable.ifentry.ifmtu
The size of the largest datagram (in octets) which can be sent on the interface. SNAIP and SYNC
ports always return 0. IPSec tunnel interfaces will return the underlying interface if it can be
located, otherwise 0 is returned. PPP interfaces will return the negotiated MTU if the link is
connected, otherwise 0 is returned.
For example:
mib-2.interfaces.iftable.ifentry.ifmtu.21 = 1504
at\smib=mib-2.interfaces.iftable.ifentry.ifspeed
This variable displays an estimate of the interface's current bandwidth in bits per second. SNAIP
and SYNC ports will always return 0. PPP ports will always return 64000.
For example:
mib-2.interfaces.iftable.ifentry.ifspeed.1 = 64000
at\smib=mib-2.interfaces.iftable.ifentry.ifphysaddress
The interface's address at the protocol layer immediately below the network layer in the
protocol stack. For interfaces without such an address, a zero-length octet string is returned. For
PPP, SNAIP and SYNC ports, a zero-length string is returned.
at\smib=mib-2.interfaces.iftable.ifentry.ifadminstatus
The desired state of the interface. The testing state (3) indicates no operational packets can be
passed.
at\smib=mib-2.interfaces.iftable.ifentry.ifoperstatus
The current operational state of the interface. The testing state (3) indicates no operational
packets can be passed.
at\smib=mib-2.interfaces.iftable.ifentry.ifinoctets
The total number of octets received on this interface, including framing characters.
at\smib=mib-2.interfaces.iftable.ifentry.ifinucastpkts
The number of subnetwork-unicast packets delivered by this interface to a higher-layer
protocol.
at\smib=mib-2.interfaces.iftable.ifentry.ifinnucastpkts
The number of non-unicast (such as broadcast or multicast) packets delivered by this interface
to a higher-layer protocol.
at\smib=mib-2.interfaces.iftable.ifentry.ifinerrors
The number of inbound packets received by this interface that contained errors preventing them
from being delivered to a higher-level protocol.
