jnxMIMstCistPortPriority

jnxMIMstCistPortEntry 3

Contains the four most significant bits of the Port Identifier of the spanning-tree instance that can be modified by setting the CistPortPriority value. The values that are set for Port Priority must be in multiples of 16.

Indicates the port identifier of the port on the designated bridge for this port's segment.

jnxMIMstCistPortAdminP2P

jnxMIMstCistPortEntry 7

Indicates the administrative point-to-point status of the LAN segment attached to this port.

  • A value of forceTrue(0) indicates that this port must be treated as if it were connected to a point-to-point link.
  • A value of forceFalse(1) indicates that this port should be treated as having a shared media connection.
  • A value of auto(2) indicates that this port is considered to have a point-to-point link if it is an aggregator and all of its members are aggregatable, or if the MAC entity is configured for full duplex operation, either through autonegotiation or by management.

jnxMIMstCistPortOperP2P

jnxMIMstCistPortEntry 8

Indicates the operational point-to-point status of the LAN segment that is attached to this port. It indicates whether a port is considered to have a point-to-point connection or not. The value is determined by management or by autodetection, as described in the jnxMIMstCistPortAdminP2P object.

jnxMIMstCistPortAdminEdgeStatus

jnxMIMstCistPortEntry 9

jnxMIMstCistPortOperEdgeStatus

jnxMIMstCistPortEntry 10
