--The tables in this MIB allow a subset of the functionality --provided by the RowStatus textual convention. In particular --row creation is allowed using only the createAndGo method.

--That is, when adding entries to this table, this object --must be set to createAndGo(4). The instance identifier --for this object will define the values of the columns

--that make up the index.

--In the same PDU, the appropriate remaining columns --of that row must be set as well. The agent --will immediately set the value of this object to --active(1) if the row is correct. If not, the agent

--will refuse the SET request and return an --error code.

--To modify an existing entry, it must be removed --an another entry with the desired changes added.

a3ComBrgCtl OBJECT-TYPE SYNTAX INTEGER { bridging (1), noBridging (2) } ACCESS read-write STATUS mandatory DESCRIPTION



"This object determines whether bridging is performed by this system. If this is set to noBridging (2), all functions associated with bridging are disabled, including Spanning Tree, Learning, and Source Routing." REFERENCE

a3ComBrgAgeCtl OBJECT-TYPE SYNTAX INTEGER { aging (1), noAging (2) } ACCESS read-write STATUS mandatory DESCRIPTION "This object determines whether nodes that have not transmitted packets for a specified amount of time are deleted from the forwarding table. If this object is set to aging (1), entries in the forwarding table are removed after dot1dTpAgingTime seconds. This is useful in environments where nodes may be moved from one network to another. Setting this object

to noAging (2), however, improves performance." REFERENCE"NETBuilder Ref. Guide, Bridge Service parameter: CONTrol"

a3ComBrgFwallCtl OBJECT-TYPE SYNTAX INTEGER { firewall (1), noFirewall (2) } ACCESS read-write STATUS mandatory

DESCRIPTION "This object is important when the system is performing both bridging and routing. When this is set to firewall (1), the bridge discards unicast packets of a protocol that is being routed (other than the unicast packets addressed to the bridge itself). If this is set to noFirewall, the bridge forwards

those packets." REFERENCE

The AppleTalk packets require encapsulation over FDDI networks. If AppleTalk packets are to be translated

the same way as other Ethernet packets are translated, this parameter must be disabled (2).

If this object is enabled, the original format of both AT-1 (Ethernet) and AT-2 (SNAP) packets are preserved when bridging between Ethernets

over an FDDI backbone. If this is disabled, AT-2 packets are converted to Ethernet format before going across the FDDI backbone." REFERENCE

contains the value of the time interval over which the number of broadcast packets per second are calculated.

If that number exceeds the value of a3ComBrgBroadCastLimit for a particular port, the bridge will stop forwarding all broadcast packets on that port for the rest of the time interval."
