atmIfVptVccVcdSegSwitchSideLoopback

Module: Nortel-Magellan-Passport-AtmCoreMIB

OID (symbolic): Nortel-Magellan-Passport-AtmCoreMIB::atmIfVptVccVcdSegSwitchSideLoopback

OID (numeric): 1.3.6.1.4.1.562.2.4.1.114.9.20.2.100.1.20

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This attribute specifies whether switch-side segment loopback insertion should be performed on this connection.

When sameAsInterface is selected, the switch-side segment loopback for the connection is based on the segSwitchSideLoopback attribute of the connection's parent AtmIf componentif the ATM interface has switch-side segment loopback insertion turned on, then switch-side segment loopback insertion is also on for the connection.

When on or off is selected, switch-side segment loopback insertion is turned on or off respectively for the connection regardless of the provisioning of the parent AtmIf component.

Note that switch-side segment loopback insertion is not possible if the connectionPointType attribute of the Vcc or Vpc component is connectingPoint or connectionEndPoint. Switch-side segment loopback insertion is also not possible if the distributionType of the Vcc is pointToMultipoint In such cases, the associated segSwitchSideLoopbackState attribute indicates notApplicable and switch-side segment loopback insertion is not performed. Switch- side segment loopback is never possible on a Vpt.

Examples
