| l2ForwardFilterId |
.1.3.6.1.4.1.52.2501.1.2.4.1.1 |
|
A filter number which is used to get the next row from the
L2 Forwarding table. A zero implies no filter. When a number
is used, the index(s) specified in the first GET_NEXT
is used as a filter for future GET_NEXT's using the same
FilterId.
|
| l2ForwardDstMacAddr |
.1.3.6.1.4.1.52.2501.1.2.4.1.2 |
|
The destination MAC address which has been learned.
|
| l2ForwardSrcMacAddr |
.1.3.6.1.4.1.52.2501.1.2.4.1.3 |
|
The source MAC address, which is present in case
of a Flow, that has been learned by the switch.
|

|
| l2ForwardDstPort |
.1.3.6.1.4.1.52.2501.1.2.4.1.5 |
|
The physical port number in the shelf/Chassis to which the
frame will be forwarded.
A zero implies that the frame destined to this destination
MAC address will be forwarded to multiple ports. This
implies a Multicast or unknown Unicast frame.
|
| l2ForwardInPorts |
.1.3.6.1.4.1.52.2501.1.2.4.1.6 |
|
The set of physical ports to which this entry is contained in
the L2 tables. Each octet within the value of this
object specifies a set of eight ports.
The first octet specifying ports 1 through 8,
the second octet specifying ports 9 through 16, etc.
Within each octet, the least
significant bit represents the lowest numbered
port and the most significant bit represents the
highest numbered port. Thus, each port of the
bridge is represented by a single bit within the
value of this object. If that bit has a value of
'1' then that port is included in the set of
ports; the port is not included if its bit has a
value of '0'. (Note that the setting of the bit
corresponding to the port from which a frame is
received is irrelevant.) The default value of
this object is a string of zeroes of appropriate
length. The maximum number of ports/card-module
is sysHwModuleNumPorts.

The source MAC address, which is present in case
of a Flow, that has been learned by the switch.
|
| l2PriorityVlanId |
.1.3.6.1.4.1.52.2501.1.2.5.1.5 |
|
The VLAN the destination MAC address belongs to.
|
| l2PriorityInPorts |
.1.3.6.1.4.1.52.2501.1.2.5.1.6 |
|
The set of physical ports which allow this source MAC address.
Each octet within the value of this object specifies
a set of eight ports, with the first octet specifying
ports 1 through 8, the second octet specifying ports 9
through 16, etc. Within each octet, the least
significant bit represents the lowest numbered
port, and the most significant bit represents the
highest numbered port. Thus, each port of the
bridge is represented by a single bit within the
value of this object. If that bit has a value of
'1' then that port is included in the set of
ports; the port is not included if its bit has a
value of '0'. (Note that the setting of the bit
corresponding to the port from which a frame is
received is irrelevant.) The default value of
this object is a string of zeroes of appropriate
length. The maximum number of ports per Module/Card
is sysHwModuleNumPorts.
|
| l2Priority |
.1.3.6.1.4.1.52.2501.1.2.5.1.7 |
|
The priority for this L2 flow. There are four
priority levels: low, medium, high and control.
The highest priority class is reserved for router control traffic,
which leaves three classes, high, medium, and low for normal
data flows. Buffered traffic in higher priority classes is sent ahead
of pending traffic in lower priority classes, which allows latency
and throughput demands to be maintained for the higher priority traffic.
To prevent low priority traffic from waiting indefinitely as higher
priority traffic fills the wire, a weighted fair queuing mechanism provides
adjustable minimum bandwidth guarantees at each output port, thereby ensuring
that some traffic from each priority class always gets through.

| l2FilterIndex |
.1.3.6.1.4.1.52.2501.1.2.6.1.1 |

static-entry
Based on the restrictions and the presence of
source, destination MAC address they can be of
three types :
source-static-entry - All frames with a source
address equal to srcMAC, coming through any of
the inPorts will be allowed/disallowed to go
to any port that is a member of the outPorts
list.
destination-static-entry - All frames with a
destination address equal to dstMAC, coming
through any of the inPorts will be allowed/
disallowed/forced to go to any port that is a
member of the outPorts list.
flow-static-entry - All frames with a source
address equal to srcMAC and a destination address
equal to dstMAC, coming through any of the inPorts
list will be allowed/disallowed to go to any port
that is a member of the outPorts list.
address-filter
Based on the restrictions and the presence of
source, destination MAC address they can be of
three types :
source-address-filter - All frames with a source
address equal to srcMAC, coming through any of
the inPorts will be filtered out.
destination-address-filter - All frames with a
destination address equal to dstMAC, coming through
any of the inPorts will be filtered out.
flow-filter - All frames with a source address equal
to srcMAC and a destination address equal to dstMAC,
coming through any of the inPorts list will be
filtered out.

bridge is represented by a single bit within the
value of this object. If that bit has a value of
'1' then that port is included in the set of
ports; the port is not included if its bit has a
value of '0'. (Note that the setting of the bit
corresponding to the port from which a frame is
received is irrelevant.) The default value of
this object is a string of zeroes of appropriate
length. The maximum number of ports/card-module

|
When the number of MAC entries on a physical port's L2 table reaches
the l2PortDemandAgeHiBound (95% full), a number of MAC entries
based on l2PortDemandAgeLowBound percentage will be removed
(aged-out) from the table.
|

The l2PortDemandAgeLowBound value determines how many MAC
entries need to be aged-out. See l2PortDemandAgeHiBound. Default
value is 85%.
Example: if - L2 table capacity = 10,000 entries
- l2PortDemandAgeHiBound = 95%
- l2PortDemandAgeLowBound = 85%
When the L2 table reaches 95% capacity (9500 MAC entries),
10% of the entries will be aged-out.

significant value but is not presently increasing,
it indicates that the problem has been occurring
but is not persistent.

it is for a protocol being processed by the local
bridging function, including bridge management
frames.
|
| l2PortOutFrames |
.1.3.6.1.4.1.52.2501.1.2.8.1.13 |

other(1) : none of the following. This would
include the case where some other
MIB object (not the corresponding
instance of dot1dTpFdbPort, nor an
entry in the dot1dStaticTable) is
being used to determine if and how
frames addressed to the value of
the corresponding instance of
dot1dTpFdbAddress are being
forwarded.

(e.g., it was learned but has since
aged-out), but has not yet been
flushed from the table.
learned(3) : the value of the corresponding
instance of dot1dTpFdbPort was
learned, and is being used.
self(4) : the value of the corresponding
instance of dot1dTpFdbAddress
represents one of the bridge's
addresses. The corresponding
instance of dot1dTpFdbPort
indicates which of the bridge's
ports has this address.

instance of dot1dTpFdbAddress is
also the value of an existing
instance of dot1dStaticAddress.
