6.2.18 STP (Spanning Tree Protocol)
If STP is enabled between switches, the STP port information is used as follows: bridge ID, designated
bridge, and port identifier are compared with the relevant remote information. If a match is found, a link
is created.
bridge, and port identifier are compared with the relevant remote information. If a match is found, a link
is created.
This STP discovery technique will only work when compatible STP protocols are running on both ports.
6.2.19 MPLS-TE Information
MPLS-TE type
The MPLS-TE tunnel source IP, destination IP and the tunnel ID information from the tunnel head (taken
from the MPLS TE Tunnel) are compared with destination IP, source IP and the tunnel ID on the tail
(taken from the MPLS TE Tunnel Segment of the LSE).
from the MPLS TE Tunnel) are compared with destination IP, source IP and the tunnel ID on the tail
(taken from the MPLS TE Tunnel Segment of the LSE).
P2MP MPLS-TE type
The MPLS-TE tunnel source IP, destination IP list and the tunnel ID information from the tunnel head
(taken from the MPLS TE Tunnel) are compared with destination IP, source IP and the tunnel ID on the
tail (taken from the MPLS TE Tunnel Segment of the LSE). The destination IP on the MPLS TE Tunnel
Segment of the LSE is contained in destination IP list of MPLS-TE tunnel.
(taken from the MPLS TE Tunnel) are compared with destination IP, source IP and the tunnel ID on the
tail (taken from the MPLS TE Tunnel Segment of the LSE). The destination IP on the MPLS TE Tunnel
Segment of the LSE is contained in destination IP list of MPLS-TE tunnel.
6.2.20 MPLS-TP Information
The local router ID, remote router ID and the tunnel ID of one MPLS-TP tunnel edge are compared to the
remote router ID, local router ID and tunnel ID of another MPLS-TP tunnel edge.
remote router ID, local router ID and tunnel ID of another MPLS-TP tunnel edge.
The information is taken from the MPLS TP Tunnel EP.
6.2.21 UCS Internal Connectivity
For UCS devices, links between different components of a device (Fabric Interconnects, IO Modules, and
Blade Servers) are created based on peer information available via HTTP management. This information
is shown also in the UCS Manager application. For example, FIC ports connected to the ports of an IO
Module are shown in the “Peer” column of the “Fabric Ports” table under the corresponding IO Module
node, and under Fabric Port nodes in UCS Manager.

6.2.22 WWN
WWN (World Wide Name) is a unique identifier of a Fiber Channel port. Fiber Channel switches of a
fabric store a shared database of fabric ports that contains WWNs of each connected port (extension or
node) and its peer. This information is used to discover pairs of connected ports in the network. WWN
