CTRON-SSR-L2-MIB
AI MIB Summary
The CTRON-SSR-L2-MIB was designed to monitor Layer 2 processing subsystem metrics and configure filter tables on Ctron SSR platforms, but it is now deprecated in favor of standard RMON I (RFC 1757) and the ctron-ssr-policy MIB for equivalent functionality.
This module defines a schema to access SSR Layer 2 processing subsystem. This mib is no longer supported on ssr platforms. features of this mib now exist in standard mibs. RMON I RFC 1757 provides Layer 2 information and ctron-ssr-policy mib to program filter tables.

l2Group OBJECT IDENTIFIER .1.3.6.1.4.1.52.2501.1.2 |
l2LearnedEntryDiscardsThe total number of Forwarding Database entries, which have been or would have been learned, but have been discarded due to a lack of space to store them in the Forwarding Database. If this counter is increasing, it indicates that the Forwarding Database is regularly becoming full (a condition which has unpleasant performance effects on the subnetwork). If this counter has a significant value but is not presently increasing, it indicates that the problem has been occurring but is not persistent.roobsolete Counter32 .1.3.6.1.4.1.52.2501.1.2.1 |
l2LearnedMacEntriesThe total number of MAC entries. The total number is equal to the number of unique VLAN id and MAC address pairs on the switch.roobsolete Counter32 .1.3.6.1.4.1.52.2501.1.2.2 |
l2LearnedFlowEntriesThe total number of Flow entries. The total number is equal to the number of unique VLAN id, source MAC address and destination MAC address 3-tuple on the switch.roobsolete Counter32 .1.3.6.1.4.1.52.2501.1.2.3 |
l2ForwardTableA list of L2 flow entries.obsolete SEQUENCE OF L2ForwardEntry .1.3.6.1.4.1.52.2501.1.2.4 |

l2ForwardFilterIdA 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.roobsolete INTEGER .1.3.6.1.4.1.52.2501.1.2.4.1.1 |
l2ForwardDstMacAddrThe destination MAC address which has been learned.roobsolete PhysAddress (SNMPv2-TC) .1.3.6.1.4.1.52.2501.1.2.4.1.2 |

l2ForwardDstPortThe 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.roobsolete INTEGER .1.3.6.1.4.1.52.2501.1.2.4.1.5 |
l2ForwardInPortsThe 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.

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.

l2PriorityThe 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.rwobsolete Enumeration .1.3.6.1.4.1.52.2501.1.2.5.1.7 |
