Monitoring the Physical Path
You can monitor the physical path that a packet takes from a source device to a destination device by using
one of these privileged EXEC commands:
Table 17: Monitoring the Physical Path
PurposeCommand
Displays the Layer 2 path taken by the packets from
the specified source MAC address to the specified
destination MAC address.
tracetroute mac [interface interface-id]
{source-mac-address} [interface interface-id]
{destination-mac-address} [vlan vlan-id] [detail]
Displays the Layer 2 path taken by the packets from
the specified source IP address or hostname to the
specified destination IP address or hostname.
tracetroute mac ip {source-ip-address |
source-hostname}{destination-ip-address |
destination-hostname} [detail]
Executing IP Traceroute
Though other protocol keywords are available with the traceroute privileged EXEC command, they are not
supported in this release.
Note
PurposeCommand
Traces the path that
packets take through the
network.

Device# traceroute ip 192.51.100.1
Redirecting Debug and Error Message Output
By default, the network server sends the output from debug commands and system error messages to the
console. If you use this default, you can use a virtual terminal connection to monitor debug output instead of
connecting to the console port or the Ethernet management port.
Possible destinations include the console, virtual terminals, internal buffer, and UNIX hosts running a syslog
server. The syslog format is compatible with 4.3 Berkeley Standard Distribution (BSD) UNIX and its
derivatives.
