Interfaces 17.14.2
The Interfaces hierarchy consists of the ifnumber variable and the iftable node:
at\smib=mib-2.interfaces.ifnumber
The total number of interfaces on the unit. This includes Ethernet, PPP and virtual interfaces (i.e.
IPSec tunnels) and SYNC ports.
mib-2.interfaces.ifnumber = 52
at\smib=mib-2.interfaces.iftable
The iftable node contains ifentry nodes for each interface. For each table entry, an index specifier
must be appended to the end of each variable (e.g. for PPP0, 1 must be appended).
at\smib=mib-2.interfaces.iftable.ifentry
at\smib=mib-2.interfaces.iftable.ifentry.ifindex
The unique index number of the interface.
at\smib=mib-2.interfaces.iftable.ifentry.ifdescr
This variable displays information about the interface. This information is displayed in the format
-
, where:
can be one of PPP, ETH, TUN (for IPSec tunnels), SNAIP (for SNAIP
links) or SYNC, and
is the instance.
For example:
mib-2.interfaces.iftable.ifentry.ifdescr.1 = PPP-0
at\smib=mib-2.interfaces.iftable.ifentry.iftype
The type of interface, as described by the physical/link protocol below the network layer in the
pro tocol stack. Values can be one of the following:
PPP 23
ETH 6
IPSec Tunnel 131
SNAIP 17
SYNC port 118
For example:
mib-2.interfaces.iftable.ifentry.iftype.1 = 23
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
con nected, 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 proto-
col stack. For interfaces without such an address, a zero-length octet string is returned. For PPP,
SNAIP and SYNC ports, a 0 length string is returned.
