a3ComBrCentralMacCtl

Module: A3COM-PORTPATH-R6-MIB

OID (symbolic): A3COM-PORTPATH-R6-MIB::a3ComBrCentralMacCtl

OID (numeric): 1.3.6.1.4.1.43.2.17.2.1.17

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This object is used to enable or disable the Boundary Routing Central MAC feature. If this feature is enabled, (ie, if this object has the value centralMac(1)), the Central Node (in a Boundary Routing environment) will use a special internally saved MAC address as its source MAC address on this port. This will allow certain protocols (such as TCP/IP and IPX) running on the Leaf Nodes to switch to another Central Node without losing sessions.

Note, in order for this feature to operate properly, it must be enabled on all the Central Nodes attached to the same Leaf Node. Also note, this feature only applies to Central Nodes (in a Boundary Routing environment) and doesn't apply to the Leaf Nodes.

Note, when this parameter is enabled/disabled, the port itself must be disabled and then re-enabled for the new value to take effect. This is done by setting the corresponding instance of ifAdminStatus to up(1).

What is a3ComBrCentralMacCtl?

This enum enables/disables the Boundary Routing Central MAC feature, allowing the central node to use a saved MAC address. When enabled, leaf nodes can switch to alternate central nodes without session loss. Setting centralMac(1) activates the feature for seamless failover.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.2.17.2.1.17
snmpwalk -v2c -c public <target> A3COM-PORTPATH-R6-MIB::a3ComBrCentralMacCtl

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.43.2.17.2.1.17.1
snmpget -v2c -c public <target> A3COM-PORTPATH-R6-MIB::a3ComBrCentralMacCtl.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.43.2.17.2.1.17.1 i <value>
