s5EnMsTopStatus

Module: S5-ETH-MULTISEG-TOPOLOGY-MIB

OID (symbolic): S5-ETH-MULTISEG-TOPOLOGY-MIB::s5EnMsTopStatus

OID (numeric): 1.3.6.1.4.1.45.1.6.13.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Indicates if the agent is participating in multi-segment topology. The values are: topOn(1)....topology is on topOff(2)...topology is off When the value is topOff(2) the status of topology table entries is undefined. However, the agent should make its best attempt when the value is changed to topOff(2) to remove all existing instances of topology MIB objects. The agent must save the setting of this object in nonvolatile memory (i.e., save across reboots).

What is s5EnMsTopStatus?

Turns SONMP multi-segment topology discovery on or off for this device; when set to topOff(2) the topology tables become undefined and the agent tries to clear them, and the setting is saved across reboots.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.45.1.6.13.1.2
snmpwalk -v2c -c public <target> S5-ETH-MULTISEG-TOPOLOGY-MIB::s5EnMsTopStatus

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.45.1.6.13.1.2.1
snmpget -v2c -c public <target> S5-ETH-MULTISEG-TOPOLOGY-MIB::s5EnMsTopStatus.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.45.1.6.13.1.2.1 i <value>
