Circuits Filter


Use the Circuits Filter dialog box to filter the circuits that appear on the Circuits tab based on circuit type, status, protection, size, and other parameters.

Item

Description

Name

Allows you to filter circuits based on the complete or partial circuit name. If blank, the circuit name is not used to filter circuits.

Direction

Filters circuits based on circuit direction. Valid entries are:

  • Any: Direction is not used to filter circuits.

  • 1-way: Displays only one-way circuits.

  • 2-way: Displays only two-way circuits.

OCHNC Dir

Filters DWDM OCHNCs by direction:

  • East to West: Displays only east-to-west optical OCHNCs.

  • West to East: Displays only west-to-east OCHNCs.

OCHNC Wlen

Filters DWDM OCHNCs by wavelength. For example, choosing 1530.33 displays OCHNCs provisioned on the 1530.33-nm wavelength.

Status

Filters circuits by their status. Valid entries are:

  • Any: Displays circuits in any status.

  • DISCOVERED: Displays only circuits that have a complete path from source to destination.

  • DISCOVERED_TL1: Displays only TL1-created or TL1-like CTC-created circuits.

  • PARTIAL: Displays only circuits missing a connection or span to form a complete path.

  • PARTIAL_TL1: Displays only TL1-created circuit or a TL1-like CTC-created circuits that are missing a cross-connect or span to form a complete path.

See Circuit Statuses for more information about circuit statuses. (While other statuses are described in that table, filtering is only supported for DISCOVERED, DISCOVERED_TL1, PARTIAL, and PARTIAL_TL1 circuits.)

State

Filters circuits by circuit service state. Valid entries are:

  • locked: Displays only locked circuits.

  • unlocked: Displays only unlocked circuits.

  • locked[PARTIAL]: Displays only circuits with cross-connects that are not all in the unlocked-enabled service state.

See Circuit States for more information about circuit states.

Protection

Filters circuits by their protection. Valid entries are:

  • Any: Protection is not used to filter circuits.

  • 1+1: Displays only circuits that are protected by a 1+1 protection group.

  • 2F-MS-SPRing: Displays only circuits that protected by two-fiber MS-SPRings.

  • 2F-PCA: Displays only circuits that are routed on a PCA path on a two-fiber MS-SPRing. (PCA circuits are not protected.)

  • 4F-MS-SPRing: Displays only circuits are protected by a four-fiber MS-SPRing.

  • 4F-PCA: Displays only circuits that are routed on a PCA path on a four-fiber MS-SPRing. (PCA circuits are not protected.)

  • DRI: Displays only circuits that are protected by a MS-SPRing or SNCP DRI.

  • MS-SPRing: Displays only circuits that are protected by a both a two-fiber and a four-fiber MS-SPRing.

  • N/A: Displays only circuits with connections on the same node that are not protected.

  • PCA: Displays only circuits that are routed on a PCA path on both two-fiber and four-fiber MS-SPRings. (PCA circuits are unprotected.)

  • Protected: Displays only circuits that are protected by diverse SDH topologies, for example, MS-SPRing and SNCP, or SNCP and 1+1 protection.

  • SNCP: Displays only circuits that are protected by an SNCP.

  • Splitter: Displays only circuits that have their source and destination on MXPP_MR_2.5G and TXPP_MR_2.5G cards. These cards provides splitter (line-level) protection.

  • Unknown: Displays only circuits with sources and destinations on different nodes if communication is down between the nodes. This protection type appears if not all circuit components are known.

  • Unprot: Displays only circuits with sources and destinations on different nodes that were created as fully protected circuits but are no longer protected due to a system change, such as a traffic switch.

  • Y-Cable: Displays only circuits that are protected by a transponder or muxponder card Y-cable protection group.

Slot

Filters circuits based on the source or destination slot.

Port

Filters circuits based on the source or destination port.

Type

Filters circuits based on their type. Valid entries are:

  • Any: Type is not used to filter circuits.

  • VC_HO_PATH_CIRCUIT: Displays only specific VC4 circuits.

  • VC_LO_PATH_CIRCUIT: Displays only low-order path circuits.

  • VC_LO_PATH_TUNNEL: Displays only low-order path tunnels.

  • VC_LO_PATH_AGGREGATION: Displays only aggregation points.

  • VC_HO_PATH_VCAT_CIRCUIT: Displays only VC4 VCAT circuits.

  • VC_LO_PATH_VCAT_CIRCUIT: Displays only low-order path VCAT circuits.

  • OCHNC: Displays only OCHNCs.

Size

Filters circuits based on size. The sizes you can use to filter circuits include:

  • VC12

  • VC3

  • VC4

  • VC4-2c, VC4-3c, VC4-4c, VC4-6c, VC4-8c, VC4-12c, VC4-16c, VC4-64c

  • 2.5 Gb/s FEC, 2.5 Gb/s No FEC

  • Multi-rate

  • Equipment non-specific

  • 10 Gb/s FEC (forward error correction), 10 Gb/s No FEC

The check boxes shown depend on the Type field entry. If you chose Any, all sizes are available. If you chose VC_HO_PATH_CIRCUIT, only VC4 sizes are available. If you chose VC_LO_PATH_CIRCUIT, only VC12 and VC3 sizes are available. If you chose VC_LO_PATH_TUNNEL or VC_LO_PATH_AGGREGATION, only VC4 is available. If you chose VC_HO_PATH_VCAT_CIRCUIT, only VC4 and VC4-4c sizes are available. If you choose VC_LO_PATH_VCAT_CIRCUIT, only VC3 is available. If you chose OCHNC as the circuit type, Equipped non-specific, 10 Gb/s FEC, 10 Gb/s No FEC, multi-rate, 2.5 Gb/s FEC, and 2.5 Gb/s No FEC are available.
