Possible values are:


multipleNet, singleNet
                

This object determines the mode the IP protocol layer
operates in.  When in multipleNet mode, the system will
accept different network addresses for each of its
interfaces.  Routing may be disabled (via ipForwarding),
but the system will still be in routing mode, i.e., it
will keep all of its assigned addresses and it may
still participate in routing update protocols (if
configured).  When in singleNet mode, the IP address
assigned to interfaces 1 is applied to all interfaces.
ipForwarding can only be disabled, and all RIP parameters,
other than those related to listening, will be ignored.
Note, when the value of this object is changed, the new
IP address must also be set in the same PDU.  This is
required to ensure connectivity remains.

When this object transitions from multipleNet mode to singleNet
mode,
1)  ipForwarding is automatically set to not-forwarding,

2)  all RIP-IP parameters will be ignored except those
related to listening on interface 1.  These parameters
will be applied to all interfaces.

3)  an IP address must be configured, in the same request,
for interface 1.

the agent removes all other IP addresses, and the
IP address assigned to interface 1 will apply to
all interfaces.

When this object transitions back to multipleNet mode,

1)  an IP address must be assigned, in the same request,
to one of the ports,

that IP address will apply only to that port
to which it is assigned.

The IP address for interface 1 will no longer apply
to all interfaces.

2)  ipForwarding will stay at not-forwarding, and

3)  all previously ignored RIP-IP parameters will take
effect.  In order to actively route packets,
ipForwarding will need to be set to forwarding.

During this transition, there is the danger that no IP address
will have been configured for the interface that receives the
SNMP requests, in which case, the device will no longer be
manageable.  For this reason, it is suggested that the IP
addresses for the interface that receives the SNMP requests
be set in the same PDU that sets this object.    

Possible values are:


enabled, disabled
                

When the system is in singleNet mode (ie, it is
in a bridge state), this parameter controls whether
or not ARP request and replies are allowed to be
sent or received over a non-forwarding bridged port.
If this is set enabled(1), then ARP requests and replies
are allowed over non-forwarding ports.  If this is
set disabled(2), they are not allowed.

This object corresponds to the UI parameter: -arp OverBlocked.    

Possible values are:


enabled, disabled
                

This allows the RARP client function to be
enabled or disabled.  If enabled, this system
will send RARP requests.  If disabled, the system
will not send RARP requests.

This object corresponds to the UI parameter: -arp RarpCONTrol.    

Possible values are:


enabled, disabled
                

This allows the RARP server function to be
enabled or disabled.  If enabled, this system
will respond to RARP requests.  If disabled,
this system will not respond.

This object corresponds to the UI parameter: -arp RarpCONTrol.    

This table contains ARP configuration information.    

Each entry in this table contains port-specific
ARP configuration information.    

Possible values are:


proxy, noProxy
                

This object applies to ARP requests for networks or
subnetworks that are in the IP routing table.  When
this is the case, this system will respond to the
request with the MAC address of this system's
interface if the value of this object is proxy (1).
Otherwise, no ARP response is sent.

This object corresponds to the UI parameter: -arp control    

This object determines the amount of time, in hours,
an entry can stay in the ARP table.  When the
specified time elapses, the entry is deleted.  When
one sixteenth of the time elapses, ARP considers
this entry aged.  When a packet is destined for
an entry that has become aged, the system sends
an ARP request, using a unicast address, to the
destination to verify whether it is still operational.

This object corresponds to the UI parameter: -arp HoldTime.    

Possible values are:


ethernet, snap, both, auto, ethAuto, 
snapAuto, bothAuto

This parameter specifies the Ethernet header format
used for ARP requests.  If this is set to ethernet (1),
ARP sends requests with an Ethernet Version 2 header.
If this is set to snap (2), ARP sends requests with the
IEEE 802.2 and 802.3 headers, including the Snap extension.
If this is set to both (3), ARP sends two request packets,
one with Ethernet format and one with the Snap extensions.
If this is set to auto(128), the default request format is
based on the media type of the interface with which this
parameter is associated.

When GETting the value of this object, the first three
enumerations (ethernet, snap, and both) are returned if
this parmeter was explicitly set to one of these values.
If this parameter was set to auto(128), either ethAuto(129),
snapAuto(130), or bothAuto(131) will be returned, depending
on which header format is the most appropriate (which
is based on the media type of the associated interface).

This object corresponds to the UI parameter: -arp RequestFormat.    

The value of this object reflects the IP address
that is assigned to the boundary router that is
attached to this port.  This address is used when
a RARP request is received from that boundary router.

For those ports that are not attached to a boundary
router, this object will have no meaning and no
affect on the system.    

Possible values are:


enabled, disabled
                

This object specifies whether inverse arp is
enabled on this port.  Note, this affects only
Frame Relay ports.    

This table contains a set of IP network address
to SMDS Group Address pairings.    

Each entry in this table contains a single
IP network address to SMDS Group Address
mapping.  This is used in applications running
IP over SMDS.    

This is an IP network address for which there is
a corresponding SMDS Group Address.    

This is the SMDS Group Address that corresponds
to the IP network address identified by
a3IPsmdsGaIpNet.    

This object is used to add and delete entries
in this table.  See the notes describing
RowStatus at the beginning of this MIB.    

This table contains a set of X25 configuration
parameters relating to routing IP over x25 networks.    

Each entry contains a set of x25 configuration
parameters relating to routing IP over a specific port.    

The port number to which this table entry applies.    

The protocol ID that is included in all outgoing IP
packets sent over the x25 port associated with this
table entry.    

DEPRECATED
The maximum number of packets that can be queued
for a specific DTE address when the virtual circuit
or the x25 port is congested.

NOTE: this object is no longer supported by NETBuilders
running sw version 8.0 and greater.    

DEPRECATED
The maximum number of virtual circuits that can
be established concurrently for IP routing.
NOTE: this object is no longer supported by NETBuilders
running sw version 8.0 and greater.    

DEPRECATED
The maximum amount of time, in minutes, that can elapse
when there is no activity on the x25 virtual circuit
before it is cleared.  This applies to the first virtual
circuit established for a particular DTE address.  IF
more than one virtual circuit is established for the same
DTE address, all are cleared (except for the first one
established) when the first virtual circuit is not
experiencing congestion.

NOTE: this object is no longer supported by NETBuilders
running sw version 8.0 and greater.    

This object specifies the X25 User ProfileID to be used for
selecting a Virtual Circuit to send IP Packets. Range
is 0..255. If the value specified is 0 then use the DTE Profile
ID    

Possible values are:


high, medium, low, default, unknown
                

This object, which is used by the Multiple Priority Queue
feature, specifies into which queue IP packets are placed.
If this object has the value default(4), then IP packets are
placed in the system default queue as specified by
a3ComDefaultPriority.    

Possible values are:


fwdSubnetBcast, noFwdSubnetBcast
                

This table contains ICMP configuration information.    

Each entry in this table contains port-specific
ICMP configuration information.    

Possible values are:


redirect, noRedirect
                

This object controls whether ICMP issues ReDirect packets
on this port.    

Possible values are:


destUnreachable, noDestUnreachable
                

This object controls whether ICMP issues Destination
Unreachable packets on this port.    

Possible values are:


timeExceed, noTimeExceed
                

This object controls whether ICMP issues Time
Exceeded packets on this port.    

Possible values are:

When set to 2, this object can be used to remove
all dynamically learned entries from the IP routing table.
When set to 3, this object can be used to remove dynamically
learned entries from the Address Resolution Table.    

Possible values are:


relay, discard
                

This object is used to control the relaying of packets
that contain the Loose or Strict source route option.
If this object is set to relay (1), those packets are
relayed.  If this object is set to discard (2), those
packets are discarded.    

Possible values are:


split, noSplit
                

This object is used to control load splitting.  If
split (1), is specified, the traffic load is distributed
among a set of least-equal-cost paths.  These paths
are selected on a round-robin basis.  If a path is
unreachable, it is not considered a candidate for load
splitting.    

Possible values are:


info, noInfo
                

This object determines whether this system replies to
ICMP Information request packets.  If this object is
set to info (1), replies are sent.  Otherwise, no replies
are sent.    

Possible values are:


mask, noMask
                

This object determines whether this system replies
to ICMP Address Mask request packets.  If this object
is set to mask (1), replies are sent.  Otherwise, no
replies are sent.    

This table is an extension of the ipNetToMediaTable
from mibII.  Currently, this table contains objects
for controlling MAC header formats and for controlling
proxy ARP for each entry.    

Each entry in this table corresponds to an entry in the
ipNetToMediaTable.  Additional columnar objects are defined
in this table that are not in the original table.    

The interface on which this entry's equivalence
is effective.    

The IpAddress corresponding to the media-dependent
physical address.    

Possible values are:


other, ethernet, ieee, snap
                

The header format to be used when sending packets to
the destination specified by this table entry.  This
parameter only applies to networks that support MAC
addresses.  Entries that correspond to other network
types have the value other (1).    

Possible values are:


proxy, noProxy
                

If this object is set to proxy (1), the system will
respond to ARP requests for the IP address of this
entry.  If this object is set to noProxy (2), no
response will be sent.    

This table contains the IP addresses assigned to each
IP port.    

Each entry contains a single IP address and
parameters relating to routing IP over a specific port.    

Possible values are:


primary, secondary
                

When multiple IP addresses are configured for a single
interface, this object is used to determine which address
is the 'primary' address.  'Primary' addresses are used
as the source IP address in packets sent from that
interface.  When there is only one address configured for
an interface, it will be the 'primary' address.  If there
is an existing 'primary' address when this object is set
to primary (1), the existing 'primary' address will be
set to 'secondary' automatically.    

The subnet mask associated with the IP address
of this entry.  The value of the mask is an IP
address with all the network bits set to 1 and
all the host bits set to 0.

If this is not specified, the system will select
a mask based on the IP address class.    

The value of the least-significant bit in the
IP broadcast address used for sending datagrams
on the logical interface associated with the IP
address of this entry.    

The size of the largest IP datagram which is
supported by the logical interface associated
with the IP address of this entry.

If this is not specified, the system will select
a value based on the interface type.    

This object is used to add and delete entries
in this table.  See the notes describing
RowStatus at the beginning of this MIB.    

Each entry in this table corresponds to a single
entry in the ipForwardTable.  An additional columnar
object has been defined to indicate whether a dynamically
learned route may take precendence of a particular
static route.    

The destination IP address of this route.  This is
identical to ipForwardDest.    

Possible values are:


other, local, netmgmt, icmp, egp, ggp, 
hello, rip, is-is, es-is, ciscoIgrp, 
bbnSpfIgp, ospf, bgp, idpr

The routing mechanism via which this route was learned.    

The general set of conditions that would cause
the  selection  of  one multipath route (set of
next hops for a given destination) is  referred
to as 'policy'.

Unless the mechanism indicated by ipForwardPro-
to specifies otherwise, the policy specifier is
the IP TOS Field.  The encoding of IP TOS is as
specified  by  rfc1354.  Zero indicates the default
path if no more  specific policy applies.  Currently,
zero is the only TOS value supported by 3Com.    

On remote routes, the address of the next system
en route.  Otherwise, 0.0.0.0    

Possible values are:


override, noOverride
                

This object is used to identify those static routes
that may be overridden by dynamically learned routes.
For those entries in this table that represent dynamically
learned routes, this object will have the value
noOverride (2) at all times.
