efdmimRingTopology

Module: EFDMIM-MIB

OID (symbolic): EFDMIM-MIB::efdmimRingTopology

OID (numeric): 1.3.6.1.4.1.52.1.6.4.1.1.1.6

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: A bit-mapped representation of the current state of the node.

if this state: Add 2**n where n= Wrapped Node: 0 Unattached Concentrator: 1 A-A twisted ring: 2 B-B twisted ring: 3 Rooted Station: 4 SRF supported 5

Wrapped Node: set when the node's cf-state is Wrap-A, Wrap-B, Wrap-S, or Wrap- AB. Unattached Concentrator: set when a concentrator has no active A, B, or S ports. A-A Twisted ring: A twisted ring has occurred because this node's A port has been connected to another port. B-B Twisted ring: A twisted ring has occurred because this node's B port has been connected to another B port. Rooted Station: This is a station who's A, B and S ports are NOT active in tree mode. If any A, B, or S ports are active in TREE mode, this is FALSE. SRF supported: This node adheres to the status reporting frame protocol.

What is efdmimRingTopology?

Reports a bit-mapped summary of this node's current ring state, flagging conditions like a wrapped node, an unattached concentrator, an A-A or B-B twisted ring, a rooted station, or SRF protocol support, which an admin decodes to diagnose ring topology problems.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.1.6.4.1.1.1.6
snmpwalk -v2c -c public <target> EFDMIM-MIB::efdmimRingTopology

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.1.6.4.1.1.1.6.1
snmpget -v2c -c public <target> EFDMIM-MIB::efdmimRingTopology.1
