Description: Manages MAC address table, static entries, and aging on Ciena CES Carrier Ethernet switches.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CIENA-CES-MAC-MIB?

CIENA-CES-MAC-MIB is a Ciena-specific MIB for Carrier Ethernet Switching (CES) platforms that manages the switch's MAC address forwarding table, including dynamically learned and statically configured MAC entries and aging-time behavior. It exposes Layer-2 forwarding and configuration data — which MAC addresses are learned on which ports/VLANs, static MAC assignments, and aging timers — rather than classic hardware environmental data. For status monitoring it is mainly useful for verifying Layer-2 forwarding health: confirming expected MAC addresses appear on expected ports, catching MAC flapping or table overflow, and validating static entries persist as configured, rather than reporting CPU, temperature, or power-supply status directly. It builds on concepts similar to the IETF BRIDGE-MIB and standard interface indexing, though implemented as a Ciena-proprietary table. It is deployed in carrier Ethernet access and aggregation networks running Ciena CES switches where operators need to track MAC learning behavior and static forwarding entries. Engineers can download the CIENA-CES-MAC-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CIENA-CES-MAC-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

No specific object names were available in this excerpt, but based on the module description an administrator would poll the MAC address table (learned and static entries) to confirm a given client's MAC address appears on the expected port, verify statically pinned MAC entries have not been overwritten, and check the configured aging timeout to tune how quickly stale entries are flushed. A MAC address repeatedly appearing and disappearing on different ports would indicate a MAC-flapping or network-loop condition worth investigating.

What Can Be Monitored

MAC address forwarding table entries
static MAC address assignments
MAC address aging timer
port/VLAN mapping for learned MAC addresses

OID symbolic	OID numeric	Type	Access	Description
cienaCesMacMIB	1.3.6.1.4.1.1271.2.1.26			The MIB module defines the managed objects for the MAC tables available on the Ciena specific products.
cienaCesMacMIBObjects	1.3.6.1.4.1.1271.2.1.26.1
cienaCesMacScan	1.3.6.1.4.1.1271.2.1.26.1.1

I32 cienaCesMacScanAttrVs	1.3.6.1.4.1.1271.2.1.26.1.1.1.1	Integer32	read-write	The virtual switch (VS) attribute allows the user to display MAC scan table entries that are associated with the specified VS. Setting to -1 will enable all VSs to be included in the MAC scan table.
I32 cienaCesMacScanAttrRlan	1.3.6.1.4.1.1271.2.1.26.1.1.1.2	Integer32	read-write	The RLAN attribute allows the user to display MAC scan table entries that are associated with the specified RLAN. If the RLAN attribute is set to -1, then all RLANs will be shown (default value).
MAC cienaCesMacScanAttrMac	1.3.6.1.4.1.1271.2.1.26.1.1.1.3	MacAddress	read-write	The MAC and mask attributes allow the user to construct MAC scan table entries that match all or part of the specified MAC and mask attributes. The MAC scan table will only contain entries that have bits set, matching the specified MAC address and mask. This will allow the user to specify that certain bits in the MAC address must be 1's or 0's. A mask of ff:ff:ff:ff:ff:ff will be implied only when the specified MAC address will be included in the MAC table. A MAC attribute of 00:00:00:00:00:00 allowing all MACs to be included in the table (provided the other attributes match allowing the table entry to be returned).
MAC cienaCesMacScanAttrMask	1.3.6.1.4.1.1271.2.1.26.1.1.1.4	MacAddress	read-write	Refer to cienaCesMacScanAttrMac description.
