Chapter 9 Using Cisco ANA PathTracer in MPLS Networks

Using Cisco ANA PathTracer for MPLS TE Tunnels

Viewing MPLS TE Tunnel Information

Layer 2 and Layer 3 Cisco ANA PathTracer information is displayed in the Cisco ANA PathTracer windows when a path is traced over MPLS TE tunnels. To view Layer 2 path information, choose the Layer 2 tab and choose Show All from the View menu. The path information is displayed in the active tab.

Note Selecting a device or link on the map automatically highlights the related parameters in the table.

Layer 2 properties that may be displayed in the Layer 2 tab relating specifically to MPLS TE tunnels include:

MPLS TE Properties—The MPLS TE data set in an MPLS interface, mainly bandwidth allocation levels and signaling protocol.

Tunnel Oper Status—The operational state of the tunnel, either up or down. If the Tunnel Oper status is up, the Tunnel Admin Status must also be up (see the Tunnel Admin Status properties for additional information).

Tunnel Bandwidth Kbps—Tunnel configured bandwidth in Kb/s.

Tunnel Description—A textual description of the tunnel.

Tunnel Name—The interface name.

Tunnel Admin Status—The operational state of the tunnel, either up or down, however;

If the Tunnel Oper status is up, the Tunnel Admin Status must also be up.

If the Tunnel Admin status is down, the Tunnel Oper Status must also be down.

Tunnel Lockdown—If enabled, the tunnel cannot be rerouted.

Tunnel LSP ID—LSP identification number.

Tunnel Auto Route—If enabled, destinations behind the tunnel are routed through the tunnel.

Tunnel Hold Priority—The tunnel’s priority after path setup, when other tunnels try to remove it and claim its resources.

Tunnel Setup Priority—The tunnel’s priority upon path setup.

Tunnel Path Option—The tunnel’s path can be either dynamic, in which case the tunnel is routed along the ordinary routing decisions after taking into account the constraints the tunnel imposes (attributes, priority, bandwidth) or explicit, in which case the route is explicitly plotted with included and excluded links.

Tunnel Out Label—The TE tunnel’s MPLS label distinguishing the LSP selection in the adjacent (next) device.

Tunnel Affinity—The tunnel’s preferential bits for specific links.

Tunnel Destination AddressThe IP address of the device in which the tunnel ends.

Tunnel Peak Rate Kbps—Flow specification measured for this tunnel (in Kbps).

Tunnel Out Interface—The interface through which the tunnel exits the device.

Tunnel Burst Kbps—Tunnel burst rate (in Kb/s).

Tunnel Average Rate Kbps—Tunnel average rate (in Kb/s).

Tunnel Affinity Mask—Dictates which bits from the tunnel’s affinity should be compared to the link’s attribute bits.
