Interfaces hierarchy of smib commands
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 router. This includes Ethernet, PPP and virtual interfaces
(such as 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 (such as 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 <interface type>-<instance>, where:
<interface type> can be one of PPP, ETH, TUN (for IPSec tunnels), SNAIP (for SNAIP links) or
SYNC, and
<instance> 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
protocol 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
