Ethernet fabric traceroute
NOTE
All nodes in the VCS cluster must have the NETCONF interface availability for L2TraceRoute and must
be running Network OS 3.0.0 or later.
Traceroute diagnostics enables you to determine the connectivity, path, and reachability of the
Ethernet fabric between a source port and a destination port within an individual VCS fabric. You
can perform traceroute diagnostics from any RBridge where the source MAC address is learned in
the VCS cluster and that RBridge becomes the starting node for the traceroute packet. Once
configured, the traceroute request identifies the Equal Cost Multi-Path (ECMP) path a packet takes
from the source address to a destination address. Traceroute performs a hop-by-hop inspection
between two-end device MAC addresses to identify the traffic loss and any points of congestion in
the path.
Tracing Ethernet fabric routes
1. Select Monitor > Diagnostics > Ethernet Fabric Traceroute.
The Ethernet Fabrics Traceroute for Ethernet_Fabric dialog box displays (see Figure 225 ).

2. Select a source address from the Source list or enter a MAC address or IP address.
This list contains all the discovered port MAC addresses (host or device) connected to the VCS
cluster.
If you enter a MAC address, the MAC address must have been learned from one member of the
VCS cluster and must be in xxxx.xxxx.xxxx format. If you enter an IP address, it must be in
xxx.xxx.xxx.xxx format and the associated MAC address must have been learned from one
member of the VCS cluster.
3. Select a destination address from the Destination list or enter a MAC address or IP address.
This list contains all the discovered port MAC addresses (host or device) connected to the VCS
cluster.
If you enter a MAC address, the MAC address must have been learned from one member of the
VCS cluster and must be in xxxx.xxxx.xxxx format. If you enter an IP address, it must be in
xxx.xxx.xxx.xxx format and the associated MAC address must have been learned from one
member of the VCS cluster.
